     You should read the following summary together with the more detailed
information concerning our company and the common stock being registered
appearing elsewhere in this prospectus. Because this is only a summary, you
should read the rest of this prospectus before you invest in our common stock.
Read this entire prospectus carefully, especially the risks described under
"Risk Factors."


                                    SCANSOFT


     We are a leading provider of software that allows users to convert speech,
documents and images into information used within digital applications. Our
products and technologies automate manual processes and help enterprises,
professionals and consumers increase productivity, reduce costs and save time.
Our products are built upon speech and digital capture technologies, and are
sold as solutions into the financial, legal, healthcare, government,
telecommunications and automotive industries. Our speech technologies transform
speech into text and text into speech, and enable the voice control of hardware
and software applications. Our digital capture technologies transform text and
images into digital documents and information.



     Our software is delivered as independent applications or as technology
included by others into larger integrated systems, such as enabling voice
control within customer service call centers or enabling document conversion
capabilities within networked digital copiers. Our speech solutions
automatically create documents from speech, transform text into synthesized
speech, and enable seamless interaction with hardware and software systems
simply by speaking. Our digital capture solutions eliminate the need to manually
reproduce documents, automate the integration of documents into business
systems, and enable the use of electronic documents and forms within XML,
Internet, mobile and other business applications. Our products and technologies
deliver a measurable return on investment to our customers.



     Our technologies are based on complex mathematical formulas, which require
large amounts of linguistic and image data, acoustic models and recognition
techniques. A significant investment in capital and time would be necessary to
replicate our current capabilities, and we continue to build upon our leadership
position. Our speech technology has industry-leading recognition accuracy,
provides natural sounding synthesized speech in 20 languages, and supports a
broad range of hardware platforms and operating systems. Our digital capture
technology is recognized as the most accurate in the industry, with rates as
high as 99.8%, and supports more than 100 languages. Our technologies are
covered by more than 300 patents or patent applications.



     We have established relationships with more than 2,000 resellers, including
leading system vendors, independent software vendors, value-added resellers and
distributors, through which we market and distribute our products and solutions.
In speech, companies such as Cisco, Dictaphone, Lucent, GSL and Microsoft embed
our technologies into telecommunications systems, as well as automotive, PC or
multimedia applications. In digital capture, companies such as Brother, Canon,
Hewlett-Packard, Visioneer and Xerox include our technology in digital copiers,
printers and scanners, as well as multifunction devices that combine these
capabilities. In addition, companies such as Corel, Kofax, Lockheed Martin,
Microsoft and Symantec embed our digital capture technology into their
commercial software applications. Each of these listed companies is one of our
five largest revenue producing OEM customers, in their respective category, for
the year ended December 31, 2002. We also maintain an extensive network of
value-added resellers to address the needs of specific markets, such as
financial, legal, healthcare and government. We sell our applications to
enterprises, professionals and consumers through major independent distributors
that deliver our products to computer superstores, consumer electronic stores,
mail order houses, office superstores and eCommerce Web sites.



     ScanSoft, Inc. was incorporated as Visioneer, Inc. in March 1992 and
through December 1998, developed and sold scanner hardware and software
products. On January 6, 1999, Visioneer sold the hardware business and the
Visioneer brand name to Primax Electronics, Ltd., and on March 2, 1999,
Visioneer acquired ScanSoft, in a cash election merger, from Xerox Corporation.
The corporate entity


                                        1


"Visioneer" survived the merger, but changed its name to "ScanSoft, Inc." In
addition, Visioneer changed the ticker symbol for its common stock that trades
on the Nasdaq National Market, to "SSFT."


     On August 11, 2003, we acquired all of the outstanding stock of SpeechWorks
International, Inc. ("SpeechWorks"), a leading provider of software products and
professional services that enable enterprises, telecommunications carriers and
government organizations to offer automated, speech-activated services over any
telephone, in exchange for 0.860 of a share of our common stock for each
outstanding share of SpeechWorks stock. This transaction resulted in the
issuance of approximately 32.5 million shares of our common stock, representing
approximately 33% of our outstanding common stock after the completion of the
acquisition.



     The acquisition of SpeechWorks enhances our ability to promote our products
and comprehensively address the needs of the system integrators in the United
States telephony markets. The addition of SpeechWorks' professional services
organization will enable us to support major accounts, channel partners and
telecommunications firms, as well as deliver complete solutions. In addition,
the acquisition enhances our strengths in key vertical markets, including
multiple deployments in travel/hospitality, financial services and government,
thereby expanding our market share in these key markets and expertise in
developing applications and solutions for these industries.



     The intellectual property we acquired from SpeechWorks represents a
complete portfolio of technologies for distributed conversational user interface
applications. These technologies include SpeechWorks 6.5 and OpenSpeech,
recognition engines running on servers for network based applications, and
Speechify, a server based text-to-speech product for telephony applications. In
addition, SpeechWorks has a number of recognition and synthesis technologies for
embedded speech applications, which run in automobiles, mobile telephones and
other devices with processing power or memory limitations.



     The acquisition of Speechworks also augments our speech research and
development capabilities by adding an experienced application development team.
The SpeechWorks team has significant accumulated expertise in developing tools
and techniques to produce telephony call center applications.


     We maintain executive offices and principal facilities at 9 Centennial
Drive, Peabody, MA 01960. Our telephone number is (978) 977-2000. We maintain a
web site at www.ScanSoft.com.

                                  RISK FACTORS

     You should carefully consider the risks described below before making your
decision to invest in our common stock. The risks and uncertainties described
below are not the only ones facing us. Additional risks and uncertainties not
presently known to us or that we do not currently believe are important to an
investor may also harm our business operations. If any of the events,
contingencies, circumstances or conditions described in the following risks
actually occur, our business, financial condition or our results of operations
could be seriously harmed. If that happens, the trading price of our common
stock could decline and you may lose part or all of the value of any shares held
by you.

RISKS RELATING TO OUR BUSINESS

  OUR QUARTERLY OPERATING RESULTS ARE SUBJECT TO FLUCTUATIONS AND SEASONALITY.
  IF WE FAIL TO MEET THE EXPECTATIONS OF SECURITIES ANALYSTS OR INVESTORS, OUR
  SHARE PRICE MAY DECREASE SIGNIFICANTLY.

     Our revenue and operating results have fluctuated in the past and may not
meet the expectations of securities analysts or investors in the future. If this
occurs, the price of our common stock would likely decline. Factors that may
cause fluctuations in our operating results include the following:

     - slowing sales by our distribution and fulfillment partners to their
       customers, which may place pressure on these partners to reduce purchases
       of our products;

     - volume, timing and fulfillment of customer orders;

     - customers delaying their purchase decisions in anticipation of new
       versions of products;

     - customers delaying, canceling or limiting their purchases as result of
       the threat or results of terrorism or military actions taken by the
       United States or its allies;

     - introduction of new products by us or our competitors;

     - seasonality;

     - reduction in the prices of our products in response to competition or
       market conditions;

     - returns and allowance charges in excess of recorded amounts;

     - timing of significant marketing and sales promotions;

     - increased expenditures incurred pursuing new product or market
       opportunities;

     - inability to adjust our operating expenses to compensate for shortfalls
       in revenue against forecast;

     - demand for products; and

     - general economic trends as they affect retail and corporate sales.

     Due to the foregoing factors, among others, our revenue and operating
results are difficult to forecast. Our expense levels are based in significant
part on our expectations of future revenue. Therefore, our failure to meet
revenue expectations would seriously harm our business, operating results,
financial condition and cash flows. Further, an unanticipated decline in revenue
for a particular quarter may disproportionately affect our profitability because
a relatively small amount of our expenses are intended to vary with our revenue
in the short term.

  WE HAVE A HISTORY OF LOSSES. WE MAY INCUR LOSSES IN THE FUTURE.


     We sustained recurring losses from operations in each reporting period
through December 31, 2001. We reported a net loss of $(2.6) million and net
income of $0.1 million in the quarters ended June 30, 2003 and March 31, 2003
and net income of $6.3 million for the fiscal year ended December 31, 2002,
respectively. If we are unable to return to profitability, the market price for
our stock may decline, perhaps substantially.


                                        3



  OUR BUSINESS COULD BE HARMED IF WE DO NOT SUCCESSFULLY MANAGE THE INTEGRATION
  OF THE BUSINESSES THAT WE ACQUIRE, INCLUDING OUR RECENTLY COMPLETED
  ACQUISITION OF SPEECHWORKS.



     As part of our business strategy, we have in the past acquired, and expect
to continue to acquire, other businesses and technologies. Our recent
acquisitions of the speech and language technology operations of Lernout &
Hauspie Speech Products N.V. and certain of its affiliates, including L&H
Holdings USA, Inc. (collectively, L&H) and the Speech Processing Telephony and
Voice Control business units from Philips required substantial integration and
management efforts. Our recently completed acquisition of SpeechWorks
International, Inc., will pose similar, and potentially greater, challenges.
Acquisitions of this nature involve a number of risks, including:



     - difficulty in transitioning and integrating the operations and personnel
       of the acquired businesses;



     - potential disruption of our ongoing business and distraction of
       management;



     - potential difficulty in successfully implementing, upgrading and
       deploying in a timely and effective manner new operational information
       systems and upgrades of our finance, accounting and product distribution
       systems;



     - difficulty in incorporating acquired technology and rights into our
       products and technology;



     - unanticipated expenses and delays in completing acquired development
       projects and technology integration;



     - management of geographically remote units both in the United States and
       internationally;



     - impairment of relationships with partners and customers;



     - entering markets or types of businesses in which we have limited
       experience; and



     - potential loss of key employees of the acquired company.



     As a result of these and other risks, we may not realize anticipated
benefits from our acquisitions. Any failure to achieve these benefits or failure
to successfully integrate acquired businesses and technologies could seriously
harm our business. The size of the SpeechWorks acquisition significantly
increases both the scope and consequences of our integration risks.



  OUR OPERATING RESULTS COULD BE ADVERSELY AFFECTED AS A RESULT OF PURCHASE
  ACCOUNTING TREATMENT, AND THE CORRESPONDING IMPACT OF AMORTIZATION OF OTHER
  INTANGIBLES RELATING TO OUR RECENTLY COMPLETED ACQUISITION OF SPEECHWORKS, IF
  THE RESULTS OF THE COMBINED COMPANY DO NOT OFFSET THESE ADDITIONAL EXPENSES.



     Under accounting principles generally accepted in the United States of
America, ScanSoft will account for the acquisition of SpeechWorks using the
purchase method of accounting. Under purchase accounting, ScanSoft will record
the market value of its common stock issued in connection with the acquisition
and the amount of direct transaction costs as the cost of acquiring SpeechWorks.
ScanSoft will allocate that cost to the individual assets acquired and
liabilities assumed, including various identifiable intangible assets such as
acquired technology, acquired trade names, and acquired customer relationships
and assumed above-market lease liabilities based on their respective fair
values. Intangible assets generally will be amortized over a four to ten year
period. The amount of purchase price allocated to goodwill will be approximately
$119 million and the amount allocated to identifiable intangible assets will be
approximately $14 million. Goodwill is not subject to amortization but is
subject to at least an annual impairment analysis, which may result in an
impairment charge if the carrying value exceeds its implied fair value. If other
identifiable intangible assets were amortized in equal quarterly amounts over a
six-year period following completion of the acquisition of SpeechWorks, the
accounting charge attributable to these items would be approximately $0.6
million per quarter and $2.3 million per fiscal year. As a result, purchase
accounting treatment of the acquisition could decrease net income for ScanSoft
in the foreseeable future, which could have a material and adverse effect on the
market value of ScanSoft common stock.


                                        4



  THE COMBINED COMPANY WILL BE MANAGED BY A MANAGEMENT TEAM CONSISTING OF
  CURRENT SCANSOFT AND SPEECHWORKS EXECUTIVES, AND THIS MANAGEMENT TEAM MAY
  UNDERTAKE A STRATEGY AND BUSINESS DIRECTION WHICH IS DIFFERENT FROM THAT WHICH
  WOULD BE UNDERTAKEN BY SCANSOFT'S CURRENT MANAGEMENT TEAM.



     The new management team of the combined company will consist of certain
current ScanSoft and SpeechWorks executives. The manner in which the new
management team conducts the business of the combined company, and the direction
in which the new management team moves the business, may differ from the manner
and direction in which the current management of either ScanSoft or SpeechWorks
would direct the combined or separate companies on a stand-alone basis. Such
control by the new management team, together with the effects of future market
factors and conditions, could ultimately evolve into an integration and business
strategy that, when implemented, differs from the strategy and business
direction currently recommended by ScanSoft's or SpeechWorks' current respective
management and board of directors. The new management team, and any change in
business or direction, may not improve, and could adversely impact, the combined
company's financial condition and results of operations.



  A LARGE PART OF OUR REVENUE IS DEPENDENT ON CONTINUED DEMAND FOR OUR PRODUCTS
  FROM OEM PARTNERS. A SIGNIFICANT REDUCTION IN OEM REVENUE WOULD SERIOUSLY HARM
  OUR BUSINESS, RESULTS OF OPERATIONS, FINANCIAL CONDITION AND STOCK PRICE.


     Many of our technologies are licensed to partners that incorporate our
technologies into solutions that they sell to their customers. The commercial
success of these licensed products depends to a substantial degree on the
efforts of these licensees in developing and marketing products incorporating
our technologies. The integration of our technologies into their products takes
significant time, effort and investment, and products incorporating our
technologies may not be successfully implemented or marketed by our licensees.


     OEM revenue represented 34% and 35% of our consolidated revenue for the
year ended December 31, 2002 and for the six months ended June 30, 2003,
respectively. A select few of our OEM partners account for a majority of our OEM
revenues. Our partners are not required to continue to bundle or embed our
software, and they may choose the software products of our competitors in
addition to, or in place of, our products. A significant reduction in OEM
revenue would seriously harm our business, results of operations, financial
condition and our stock price.


  SPEECH TECHNOLOGIES MAY NOT ACHIEVE WIDESPREAD ACCEPTANCE BY BUSINESSES, WHICH
  COULD LIMIT OUR ABILITY TO GROW OUR SPEECH BUSINESS.

     The market for speech technologies is relatively new and rapidly evolving.
Our ability to increase revenue in the future depends in large measure on
acceptance by both our customers and the end users of speech technologies in
general and our products in particular. The continued development of the market
for our current and future speech solutions will also depend on the following
factors:

     - widespread deployment and acceptance of speech technologies;

     - consumer demand for speech-enabled applications;

     - development by third-party vendors of applications using speech
       technologies; and

     - continuous improvement in speech technology.


     Sales of our speech products would be harmed if the market for speech
software does not continue to develop or develops more slowly than we expect,
and, consequently, our business could be harmed.


  WE HAVE GROWN AND MAY CONTINUE TO GROW THROUGH ACQUISITIONS, WHICH MAY RESULT
  IN SIGNIFICANT INTANGIBLE ASSETS, DILUTION OF OUR EXISTING STOCKHOLDERS, USE
  OF CASH AND OTHER RISKS.


     We have made several significant acquisitions over the last two years,
including the purchase of certain businesses and intellectual property from
Philips and the recently completed acquisition of SpeechWorks on August 11,
2003, and may acquire additional complementary assets, technologies or

                                        5



businesses in the future. Our past acquisitions have given rise to, and future
acquisitions may result in, substantial levels of intangible assets that will be
amortized or subject to impairment analyses in future years, and our future
results will be adversely affected if we do not achieve benefits from these
acquisitions commensurate with amortization and potential impairment charges.
For example, our acquisition of Caere Corporation included a substantial
write-off of acquired in-process research and development costs, and this also
may occur as a result of other acquisitions.



     In connection with the Caere and the L&H acquisitions, we issued 19.0
million and 7.4 million shares of our common stock respectively, and in
connection with the SpeechWorks acquisition, we issued 32.5 million shares of
our common stock. We may continue to issue equity securities for future
acquisitions and working capital purposes that could dilute our existing
stockholders. In connection with the L&H acquisition, we issued a promissory
note for $3.5 million. Under the terms of the Philips acquisition, we paid 3.1
million euros in cash at closing, subject to adjustment in accordance with the
provisions of the purchase agreement, as amended, and agreed to pay an
additional 1.0 million euros in cash prior to December 31, 2003, issued a 5.0
million euro note due December 31, 2003 and bearing 5.0% interest per annum and
issued a $27.5 million three-year, zero-interest subordinated debenture,
convertible at any time at Philips' option into shares of our common stock at
$6.00 per share. Future acquisitions may also require us to expend significant
funds or incur debt. If we expend funds or incur additional debt, our ability to
obtain financing for working capital or other purposes could decrease.



  SALES OF OUR DOCUMENT AND PDF CONVERSION PRODUCTS AND OUR DIGITAL PAPER
  MANAGEMENT PRODUCTS REPRESENTED APPROXIMATELY 51% AND 42%, RESPECTIVELY, OF
  OUR REVENUE FOR THE YEAR ENDED DECEMBER 31, 2002 AND FOR THE SIX MONTHS ENDED
  JUNE 30, 2003. ANY REDUCTION IN REVENUE FROM THESE PRODUCT AREAS COULD
  SERIOUSLY HARM OUR BUSINESS.



     Historically, a few product areas have generated a substantial portion of
our revenues. For the year ended December 31, 2002, our document and PDF
conversion products represented approximately 39% of our revenue and our digital
paper management products represented approximately 12% of our revenue. For the
six months ended June 30, 2003, our document and PDF conversion products
represented approximately 25% of our revenue, and our digital paper management
products represented approximately 17% of our revenue. A significant reduction
in the revenue contribution from these product areas could seriously harm our
business, results of operations, financial condition, cash flows and stock
price.


  THE PROTECTION OF OUR PROPRIETARY TECHNOLOGY AND INTELLECTUAL PROPERTY IS KEY
  TO OUR SUCCESS.

     We rely heavily on our proprietary technology, trade secrets and other
intellectual property. Unauthorized parties may attempt to copy aspects of our
products or to obtain and use information that we regard as proprietary.
Policing unauthorized use of our products is difficult and we may not be able to
protect our technology from unauthorized use. Additionally, our competitors may
independently develop technologies that are substantially the same as or
superior to our technologies. In addition, the laws of some foreign countries do
not protect our proprietary rights to the same extent as the laws of the United
States. Although the source code for our proprietary software is protected both
as a trade secret and as a copyrighted work, litigation may be necessary to
enforce our intellectual property rights, to protect our trade secrets, to
determine the validity and scope of the proprietary rights of others, or to
defend against claims of infringement or invalidity. Litigation, regardless of
the outcome, can be very expensive and can divert management efforts.

  THIRD PARTIES HAVE CLAIMED AND MAY CLAIM IN THE FUTURE THAT WE ARE INFRINGING
  THEIR INTELLECTUAL PROPERTY. WE COULD BE EXPOSED TO SIGNIFICANT LITIGATION OR
  LICENSING EXPENSES OR BE PREVENTED FROM SELLING OUR PRODUCTS IF SUCH CLAIMS
  ARE SUCCESSFUL.


     Like other technology companies, from time to time, we are subject to
claims that we or our customers may be infringing or contributing to the
infringement of the intellectual property rights of others. We may be unaware of
intellectual property rights of others that may cover some of our technologies
and products. If it appears necessary or desirable, we may seek licenses for
these intellectual

                                        6



property rights. However, we may not be able to obtain licenses from some or all
claimants, the terms of any offered licenses may not be acceptable to us, and we
may not be able to resolve disputes without litigation. Any litigation regarding
intellectual property could be costly and time-consuming and could divert the
attention of our management and key personnel from our business operations. In
the event of a claim of intellectual property infringement, we may be required
to enter into costly royalty or license agreements. Third parties claiming
intellectual property infringement may be able to obtain injunctive or other
equitable relief that could effectively block our ability to develop and sell
our products.



     On August 11, 2003, we acquired all of the outstanding stock of SpeechWorks
International, Inc. ("SpeechWorks"), a leading provider of software products and
professional services that enable enterprises, carriers and government
organizations to offer automated, speech-activated services over any telephone,
in exchange for 0.860 of a share of our common stock for each outstanding share
of SpeechWorks stock. On July 15, 2003, Elliott Davis filed an action against
SpeechWorks in the United States District Court for the Western District for New
York (Buffalo) claiming patent infringement. Damages are sought in an
unspecified amount. In the lawsuit, Davis alleges that SpeechWorks is infringing
United States Patent No. 4,802,231 entitled "Pattern Recognition Error Reduction
System" (the " '231 Patent"). The '231 Patent generally discloses techniques for
a pattern recognition system and method wherein errors are reduced by creating
independent error templates which correspond to patterns which tend to be
erroneously matched and linked error templates which are linked to specified
reference templates which are stored for comparison. Although SpeechWorks has
several products in the speech recognition technology field, we believe that the
products do not infringe the '231 Patent because SpeechWorks does not use the
claimed techniques. We filed an Answer and Counterclaim to Davis's Complaint on
August 25, 2003. We believe this claim has no merit, and we intend to defend the
action vigorously.



     On November 27, 2002, AllVoice Computing plc filed an action against us in
the United States District Court for the Southern District of Texas claiming
patent infringement. Damages are sought in an unspecified amount. In the
lawsuit, AllVoice alleges that we are infringing United States Patent No.
5,799,273 entitled "Automated Proofreading Using Interface Linking Recognized
Words to Their Audio Data While Text Is Being Changed" (the " '273 Patent"). The
'273 Patent generally discloses techniques for manipulating audio data
associated with text generated by a speech recognition engine. Although we have
several products in the speech recognition technology field, we believe that
these products do not infringe the '273 Patent because, in addition to other
defenses, our products do not use the claimed techniques. We filed an Answer on
December 23, 2002. We believe this claim has no merit, and we intend to defend
the action vigorously.



     On December 28, 2001, we were sued for patent infringement by the
Massachusetts Institute of Technology and Electronics For Imaging, Inc. We were
one of more than 200 defendants named in this suit. Damages are sought in an
unspecified amount. We filed an Answer and Counterclaim on June 28, 2002. We
believe this claim has no merit, and we intend to defend this action vigorously.



     On August 16, 2001, we were sued by Horst Froessl for patent infringement.
Damages are sought in an unspecified amount. We filed an Answer and Counterclaim
on September 19, 2001. We believe this claim has no merit, and we intend to
defend the action vigorously.



     We believe that the final outcome of the current litigation matters
described above will not have a significant adverse effect on our financial
position and results of operations and we believe that we will not be required
to expend a significant amount of resources defending such claims. However,
should we not prevail in these litigation matters of if we are required to
expend a significant amount of resources defending such claims, our operating
results, financial position and cash flows could be adversely impacted. If any
third parties are successful in intellectual property infringement claims
against us, we may be subject to significant damages or injunctions and our
operating results and financial position could be harmed.


                                        7



  THE MARKETS IN WHICH WE OPERATE ARE HIGHLY COMPETITIVE AND RAPIDLY CHANGING.
  WE MAY BE UNABLE TO COMPETE SUCCESSFULLY AGAINST NEW ENTRANTS AND ESTABLISHED
  COMPANIES WITH GREATER RESOURCES.



     There are a number of companies that develop or may develop products that
compete in our targeted markets; however, there is no one company that competes
with us in all of our product areas. The individual markets in which we compete
are highly competitive, and are rapidly changing. Within digital capture, we
compete directly with ABBYY, I.R.I.S. and NewSoft. Within speech, we compete
with AT&T, IBM and Nuance Communications, among others. Vendors such as Adobe
and Microsoft offer solutions that can be considered alternatives to some of our
solutions. In addition, a number of smaller companies produce technologies or
products that are in some markets competitive with our solutions. Current and
potential competitors have established, or may establish, cooperative
relationships among themselves or with third parties to increase the ability of
their technologies to address the needs of our prospective customers.


     The competition in these markets could adversely affect our operating
results by reducing the volume of the products we sell or the prices we can
charge. Some of our current or potential competitors have significantly greater
financial, technical and marketing resources than we do. These competitors may
be able to respond more rapidly than we can to new or emerging technologies or
changes in customer requirements. They may also devote greater resources to the
development, promotion and sale of their products than we do. The price and
performance of our products and technologies may not be superior relative to the
products of our competitors. As a result, we may lose competitive position,
which loss could result in lower prices, fewer customer orders, reduced revenue,
reduced gross margins and loss of market share. Our products and technologies
may not achieve market acceptance or sell at favorable prices, which could hurt
our revenue, results of operations and the price of our common stock.

     Some of our customers, such as Microsoft, have developed or acquired
products or technologies that compete with our products and technologies. These
customers may give higher priority to the sale of these competitive products or
technologies. To the extent they do so, market acceptance and penetration of our
products, and therefore our revenue, may be adversely affected.

     Our success will depend substantially upon our ability to enhance our
products and technologies and to develop and introduce, on a timely and
cost-effective basis, new products and features that meet changing customer
requirements and incorporate technological advancements. If we are unable to
develop new products and enhance functionalities or technologies to adapt to
these changes, or are unable to realize synergies among our acquired products
and technologies, our business will suffer.

  OUR SOFTWARE PRODUCTS MAY HAVE BUGS, WHICH COULD RESULT IN DELAYED OR LOST
  REVENUE, EXPENSIVE CORRECTION, LIABILITY TO OUR CLIENTS AND CLAIMS AGAINST US.

     Complex software products such as ours may contain errors, defects or other
software bugs. Defects in the solutions or products that we develop and sell to
our customers could require expensive corrections and result in delayed or lost
revenue, adverse client reaction and negative publicity about us or our products
and services. Customers who are not satisfied with any of our products could
bring claims against us for damages, which, even if unsuccessful, would likely
be time-consuming to defend, and could result in costly litigation and payment
of damages. Such claims could harm our financial results and competitive
position.

  WE RELY ON A SMALL NUMBER OF DISTRIBUTION AND FULFILLMENT PARTNERS, INCLUDING
  1450, DIGITAL RIVER, INGRAM MICRO AND TECH DATA, TO DISTRIBUTE MANY OF OUR
  PRODUCTS. ANY DISRUPTION IN THESE CHANNELS COULD HARM OUR RESULTS OF
  OPERATIONS.


     Our products are sold through, and a substantial portion of our revenue is
derived from, a network of over 2000 channel partners, including value-added
resellers, computer superstores, consumer electronic stores, mail order houses,
office superstores and eCommerce Web sites. We rely on a small number of
distribution and fulfillment partners, including 1450, Digital River, Ingram
Micro and Tech Data to serve this network of channel partners. For the year
ended December 31, 2002, two distribution and fulfillment partners, Ingram Micro
and Digital River, accounted for 25% and 17% of our consolidated revenue,

                                        8



respectively. During the six-month period ended June 30, 2003, Ingram Micro and
Digital River accounted for 22% and 15% of our consolidated revenue,
respectively. A disruption in these distribution and fulfillment partner
relationships could negatively affect our results of operations in the short
term. Any disruption for which we are unable to compensate could have a more
sustained impact on our results of operations.


  A SIGNIFICANT PORTION OF OUR ACCOUNTS RECEIVABLE IS CONCENTRATED AMONG OUR
  THREE LARGEST DISTRIBUTION AND FULFILLMENT PARTNERS, INGRAM MICRO, INC., TECH
  DATA CORPORATION, AND DIGITAL RIVER, INC.


     Our products are sold through, and a substantial portion of our accounts
receivable is derived from, three distribution and fulfillment partners. At June
30, 2003, Ingram Micro, Tech Data and Digital River represented 10%, 3% and 8%
of our net accounts receivable, respectively. At December 31, 2002, Ingram
Micro, Tech Data and Digital River represented 16%, 11% and 9%, of our net
accounts receivable, respectively. In addition, although we perform ongoing
credit evaluations of our distribution and fulfillment partners' financial
condition and maintain reserves for potential credit losses, we do not require
collateral. While, to date, such losses have been within our expectations, we
cannot assure you that these actions will be sufficient to meet future
contingencies. If any of these distribution and fulfillment partners were unable
to pay us in a timely fashion or if we were to experience significant credit
losses in excess of our reserves, our results of operations, cash flows and
financial condition would be seriously harmed.


  A SIGNIFICANT PORTION OF OUR REVENUE IS DERIVED FROM SALES IN EUROPE AND ASIA.
  OUR RESULTS COULD BE HARMED BY ECONOMIC, POLITICAL, REGULATORY AND OTHER RISKS
  ASSOCIATED WITH THESE AND OTHER INTERNATIONAL REGIONS.


     Since we sell our products worldwide, our business is subject to risks
associated with doing business internationally. We anticipate that revenue from
international operations will represent an increasing portion of our total
revenue. Reported international revenue for the year ended December 31, 2002 and
June 30, 2003, represented 27% and 28% of our consolidated revenue for those
periods, respectively. Most of these international revenues are produced by
sales in Europe and Asia. A number of our OEM partners distribute their products
throughout the world and do not provide us with the geographical dispersion of
their products. However, based on an estimate that factors our OEM partners'
geographical revenue mix to our revenue generated from these OEM partners,
international revenue would have represented approximately 33% and 36% of our
consolidated revenue for the year ended December 31, 2002 and June 30, 2003,
respectively.



     Therefore, in addition to risks to our business based on a potential
downturn in the world economy, a region-specific downturn affecting countries in
Western Europe and/or Asia could have a negative effect on our future results of
operations.



     In addition, some of our products are developed and manufactured outside
the United States. A significant portion of the development and manufacturing of
our speech products are completed in Belgium, and a significant portion of our
digital capture research and development is conducted in Hungary. In addition,
in connection with the Philips acquisition, we have added an additional research
and development location in Germany. Our future results could be harmed by a
variety of factors associated with international sales and operations,
including:



     - changes in a specific country's or region's political or economic
       conditions.



     - trade protection measures and import or export licensing requirements
       imposed by the United States or by other countries;



     - negative consequences from changes in applicable tax laws;



     - difficulties in staffing and managing operations in multiple locations in
       many countries;



     - difficulties in collecting trade accounts receivable in other countries;
       and



     - less effective protection of intellectual property.

                                        9



  WE ARE EXPOSED TO FLUCTUATIONS IN FOREIGN CURRENCY EXCHANGE RATES.


     Because we have international subsidiaries and distributors that operate
and sell our products outside the United States, we are exposed to the risk of
changes in foreign currency exchange rates or declining economic conditions in
these countries. We generally do not engage in hedging transactions to manage
our exposure to currency fluctuations. However, in connection with the Philips
acquisition, on January 30, 2003, we entered into a forward hedge in the amount
of $5.3 million to meet our obligation to pay a 5.0 million euro promissory note
issued to Philips as part of the acquisition. Our exposure to currency rate
fluctuations could affect our results of operations and cash flows.

  IF WE ARE UNABLE TO ATTRACT AND RETAIN TECHNICAL AND OPERATIONAL PERSONNEL,
  OUR BUSINESS COULD BE HARMED.

     If any of our key employees were to leave, we could face substantial
difficulty in hiring qualified successors and could experience a loss in
productivity while any successor obtains the necessary training and experience.
Our employment relationships are generally at-will and we have had key employees
leave in the past. We cannot assure you that one or more key employees will not
leave in the future. We intend to continue to hire additional highly qualified
personnel, including software engineers and operational personnel, but we may
not be able to attract, assimilate or retain qualified personnel in the future.
Any failure to attract, integrate, motivate and retain these employees could
harm our business.


  WE HAVE IMPLEMENTED ANTI-TAKEOVER PROVISIONS, WHICH COULD DISCOURAGE OR
  PREVENT A TAKEOVER, EVEN IF AN ACQUISITION WOULD BE BENEFICIAL TO OUR
  STOCKHOLDERS.



     Provisions of our amended and restated certificate of incorporation, bylaws
and Delaware law could make it more difficult for a third party to acquire us,
even if doing so would be beneficial to our stockholders. These provisions
include:



     - a preferred shares rights agreement;



     - authorized "blank check" preferred stock;



     - prohibiting cumulative voting in the election of directors;



     - limiting the ability of stockholders to call special meetings of
       stockholders;



     - requiring that all stockholder actions be taken at meetings of our
       stockholders; and



     - establishing advance notice for nominations of directors and for
       stockholder proposals.


                                        10


RISKS RELATING TO THIS OFFERING

 FUTURE SALES OF OUR COMMON STOCK BY CERTAIN OF OUR STOCKHOLDERS COULD CAUSE OUR
 STOCK PRICE TO DECREASE.

     Upon the effectiveness of this registration statement, the 9,000,000 shares
registered hereby will be freely tradable. If the Registering Stockholders were
to sell a significant portion of their shares, or investors become concerned
about the possibility of substantial sales, the market price of our common stock
could decrease.

  THE STOCKHOLDINGS OF OUR TWO LARGEST STOCKHOLDERS MAY ENABLE THEM TO INFLUENCE
  MATTERS REQUIRING STOCKHOLDER APPROVAL.


     As of September 30, 2003, Xerox beneficially owned approximately 12.0% of
our outstanding common stock, including warrants exercisable for up to 525,732
shares of our common stock and 3,562,238 shares of our outstanding Series B
Preferred Stock, each of which is convertible into one share of our common
stock. The number of shares of common stock issuable upon exercise of the Xerox
warrant may increase in accordance with a formula defined in the warrant
agreement. The State of Wisconsin Investment Board (SWIB) is our second largest
stockholder, owning approximately 11.5% of our common stock as of September 30,
2003. Because of their large holdings of our capital stock relative to other
stockholders, Xerox and SWIB, acting individually or together, could have a
strong influence over matters requiring approval by our stockholders.


  THE MARKET PRICE OF OUR COMMON STOCK HAS BEEN AND MAY CONTINUE TO BE SUBJECT
  TO WIDE FLUCTUATIONS.


     Our stock price historically has been and may continue to be volatile.
Various factors contribute to the volatility of our stock price, including, for
example, quarterly variations in our financial results, new product
introductions by us or our competitors and general economic and market
conditions. While we cannot predict the individual effect that these factors may
have on the market price of our common stock, these factors, either individually
or in the aggregate, could result in significant volatility in our stock price
during any given period of time. Moreover, companies that have experienced
volatility in the market price of their stock often are subject to securities
class action litigation. If we were the subject of such litigation, it could
result in substantial costs and divert management's attention and resources.

                              SELLING STOCKHOLDERS

XEROX CORPORATION


     The shares of common stock to be sold by Xerox pursuant to this prospectus
were issued in connection with our acquisition of ScanSoft (then an indirect
wholly owned subsidiary of Xerox) in March 1999. In the ScanSoft acquisition,
Xerox also was issued 3,562,238 shares of non-voting Series B Preferred Stock
and a ten-year warrant, which at December 31, 2002 was exercisable for the
purchase of up to 525,732 shares of our common stock. At September 30, 2003,
Xerox owned approximately 12% of our outstanding common stock and all of our
outstanding Series B Preferred Stock.



     In addition to its share holdings in us, we have entered into multiple
non-exclusive agreements with Xerox in which we grant Xerox the royalty-bearing
right to copy and distribute certain versions of our software programs with
Xerox's multifunction peripherals. Xerox accounted for 5%, 11% and 12% of total
net revenues during each of the years ended December 31, 2002, 2001 and 2000,
respectively, amounting to $5.1 million, $7.2 million and $6.0 million,
respectively. As of December 31, 2002 and 2001, Xerox owed us $1.5 million and
$1.8 million, respectively, pursuant to these agreements, which are included in
accounts receivable. We believe that the terms of our agreements with Xerox are
no more favorable than those with unrelated parties. Additionally, Herve J.
Gallaire, Senior Vice President and Chief Technology Officer of Xerox, served as
one of our directors from June 27, 2001 until September 25, 2002.


     Other than as described above, Xerox has not had any position, office, or
other material relationship within the past three years with us or any of our
predecessors or affiliates.

(1) This prospectus and the Registration Statement of which it is a part also
    shall cover any additional shares of common stock which become issuable in
    connection with the shares registered for sale hereby by reason of any stock
    dividend, stock split, recapitalization or other similar transaction
    effected without the receipt of consideration which results in an increase
    in the number of outstanding shares of our common stock.

(2) The number presented assumes the sale of all of the shares covered by this
    prospectus and that each party acquires no additional shares of common
    stock.


(3) Based upon 99,102,000 shares outstanding as of September 30, 2003, Xerox
    currently owns approximately 12.0% of our outstanding common stock and after
    the sale of all of the shares registered hereby would own approximately 7.4%
    of our outstanding common stock. All shares are owned of record by Xerox
    Imaging Systems, Inc., a wholly-owned subsidiary of Xerox Corporation.



(4) Based upon 99,102,000 shares outstanding as of September 30, 2003, SWIB
    currently owns approximately 11.5% of our outstanding common stock and after

                              PLAN OF DISTRIBUTION

     We are registering all of the Shares on behalf of the Registering
Stockholders. All of the Shares were issued by us in private placement
transactions. We will receive no proceeds from this offering. The Registering
Stockholders may sell or distribute the Shares, from time to time depending on
market conditions and other factors, through underwriters, dealers, brokers or
other agents, or directly to one or more purchasers. We are paying substantially
all expenses incidental to their registration. The Registering Stockholders will
act independently of us in making decisions with respect to the timing, manner
and size of each sale. The sales may be made on one or more exchanges or in the
over-the-counter market or otherwise, at prices and at terms then prevailing or
at prices related to the then current market price, or in negotiated
transactions. The Registering Stockholders may effect such transactions by
selling the shares to or through broker-dealers. The Shares may be sold by one
or more of, or a combination of, the following:

     - a block trade in which the broker-dealer so engaged will attempt to sell
       the shares as agent but may position and resell a portion of the block as
       principal to facilitate the transaction,

     - purchases by a broker-dealer as principal and resale by such
       broker-dealer for its account pursuant to this prospectus,

     - an exchange distribution in accordance with the rules of such exchange,

     - ordinary brokerage transactions and transactions in which the broker
       solicits purchasers, and

     - in privately negotiated transactions.

     To the extent required, this prospectus may be amended or supplemented from
time to time to describe a specific plan of distribution. In effecting sales,
broker-dealers engaged by the Registering Stockholders may arrange for other
broker-dealers to participate in the re-sales. In connection with distributions
of such shares or otherwise, the Registering Stockholders may enter into hedging
transactions with broker-dealers or other financial institutions. In connection
with such transactions, broker-dealers or other financial institutions may
engage in short sales of our common stock in the course of hedging the positions
they assume with the Registering Stockholders. The Registering Stockholders may
also sell our common stock short and redeliver the shares to close out such
short positions. The Registering Stockholders may also enter into option or
other transactions with broker-dealers or other financial institutions which
require the delivery to such broker-dealer or other financial institution of the
shares offered hereby, which shares such broker-dealer or other financial
institution may resell pursuant to this prospectus (as supplemented or amended
to reflect such transaction). The Registering Stockholders may also pledge such
shares to a broker-dealer or other financial institution, and, upon a default,
such broker-dealer or other financial institution may effect sales of such
pledged shares pursuant to this prospectus (as supplemented or amended to
reflect such transaction). In addition, any such shares that qualify for sale
pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this
prospectus.

     In effecting sales, brokers, dealers or agents engaged by the Registering
Stockholders may arrange for other brokers or dealers to participate. Brokers,
dealers or agents may receive commissions, discounts or concessions from the
Registering Stockholders in amounts to be negotiated prior to the sale. Such
brokers or dealers and any other participating brokers or dealers may be deemed
to be "underwriters" within the meaning of the Securities Act of 1933 in
connection with such sales, and any such commissions, discounts or concessions
may be deemed to be underwriting discounts or commissions under the Securities
Act of 1933. We will pay all reasonable expenses incident to the registration of
the Shares other than any commissions and discounts of underwriters, dealers or
agents.

     In order to comply with the securities laws of certain states, if
applicable, the Shares being registered hereby must be sold in such
jurisdictions only through registered or licensed brokers or dealers. In
addition, in certain states such Shares may not be sold unless they have been
registered or qualified for sale in the applicable state or an exemption from
the registration or qualification requirement is available and there has been
compliance thereof.

                                        15


     We have agreed to indemnify the Registering Stockholders and persons
controlling the Registering Stockholders against certain liabilities, including
liabilities under the Securities Act of 1933. The Registering Stockholders have
agreed to indemnify us and certain related persons against certain liabilities,
including liabilities under the Securities Act of 1933.

     We have agreed with the Registering Stockholders to keep this Registration
Statement effective until the earlier of (i) the date on which the Shares may be
resold by the Registering Stockholders without registration and without regard
to any volume limitations by reason of Rule 144(k) under the Securities Act or
any other rule of similar effect or (ii) when all of the Shares have been sold
pursuant to the Registration Statement.

                                 LEGAL MATTERS


     The validity of the shares registered hereby will be passed upon by Wilson
Sonsini Goodrich & Rosati, Professional Corporation, Palo Alto, California.
Katharine A. Martin, one of our directors, is a member of Wilson, Sonsini,
Goodrich & Rosati. Aggregate fees and costs billed to us during the year ended
December 31, 2002 by Wilson Sonsini Goodrich & Rosati, our primary outside
corporate and securities counsel, were approximately $935,000. We believe that
the services performed by Wilson Sonsini Goodrich & Rosati were provided on
terms no more favorable than those with unrelated parties.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS


     Our Certificate of Incorporation eliminates the liability of our directors
to us for monetary damages for breach of fiduciary duty as a director to the
fullest extent permissible under Delaware law, as such law exists currently or
as it may be amended in the future. Under Delaware law, such provision may not
eliminate or limit director monetary liability for: (a) breaches of the
director's duty of loyalty to us or our stockholders; (b) acts or omissions not
in good faith or involving intentional misconduct or knowing violations of law;
(c) the payment of unlawful dividends or unlawful stock repurchases or
redemptions; or (d) transactions in which the director received an improper
personal benefit. Such limitation of liability provisions also may not limit a
director's liability for violation of, or otherwise relieve us or our directors
from the necessity of complying with, federal or state securities laws, or
affect the availability of non-monetary remedies such as injunctive relief or
rescission.

     Our Bylaws provide that we shall indemnify our directors and officers and
may indemnify our employees and other agents to the fullest extent permitted by
law. We believe that indemnification under our Bylaws covers at least negligence
and gross negligence on the part of indemnified parties. Our Bylaws also permit
us to secure insurance on behalf of any officer, director, employee or other
agent for any liability arising out of his or her actions in such capacity,
regardless of whether we would have the power to indemnify him or her against
such liability under the General Corporation Law of Delaware. We currently have
secured such insurance on behalf of our officers and directors.


     We have entered into agreements to indemnify our directors and officers, in
addition to indemnification provided for in our Bylaws. Subject to certain
conditions, these agreements, among other things, indemnify our directors and
officers for certain expenses (including attorney's fees), judgments, fines and
settlement amounts incurred by any such person in any action or proceeding,
including any action by or in the right of ScanSoft, arising out of such
person's services as a director or officer of our company, any of our
subsidiaries or any other company or enterprise to which the person provides
services at our request.

ITEM 17.  UNDERTAKINGS

     (a) The undersigned Registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement:

             (i) To include any prospectus required by Section 10(a) (3) of the
        Securities Act of 1933, as amended (the "Securities Act");


             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of this Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in this Registration Statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes
        in volume and price represent no more than a 20% change in the maximum
        aggregate offering price set forth in the "Calculation of Registration
        Fee" table in the effective registration statement; and



             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in this Registration Statement
        or any material change to such information in this Registration
        Statement.



        provided, however, that the undertakings set forth in clauses (i) and
        (ii) above shall not apply if the information required to be included in
        a post-effective amendment by these clauses is contained in periodic
        reports filed by the registrant pursuant to Section 13 or Section 15(d)
        of the Exchange Act that are incorporated by reference in this
        Registration Statement.


                                       II-3


          (2) That, for the purpose of determining any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be a
     new registration statement relating to the securities offered herein, and
     the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of this offering.


     (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.



     (c) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.


                                       II-4


                                   SIGNATURES


     Pursuant to the requirements of the Securities Act, Registrant duly
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing a Form S-3 and has duly caused this Post-Effective
Amendment No. 2 on Form S-3 to Form S-1 to be signed on its behalf by the
undersigned, thereunto duly authorized, in the City of Peabody, State of
Massachusetts, on the 16th day of October, 2003.
