     This Amendment No. 2 to Schedule 13D ("Amendment No. 2") amends the
Schedule 13D originally filed on April 19, 2004 ("Original 13D") as amended by
Amendment No. 1 to Schedule 13D ("Amendment No. 1") filed on May 5, 2005 (as so
amended, the "Amended 13D"), each filed on behalf of Warburg Pincus Private
Equity VIII, L.P., a Delaware limited partnership ("WP VIII"), Warburg Pincus &
Co., a New York general partnership ("WP"), Warburg Pincus LLC, a New York
limited liability company ("WP LLC") and, with respect to Amendment No. 1 and
this Amendment No. 2, Warburg Pincus Partners LLC (f/k/a E.M. Warburg Pincus &
Co., LLC), a New York limited liability company ("WPP LLC" and, together with WP
VIII, WP and WP LLC, the "Reporting Persons"). This Amendment No. 2 relates to
the common stock, par value $0.001 per share, of ScanSoft, Inc., a Delaware
corporation formerly known as Visioneer, Inc. (the "Company"). The holdings of
the Reporting Persons reported in this Amendment No. 2 include the holdings of
Warburg Pincus Netherlands Private Equity VIII, C.V. I ("WPNPE I") and Warburg
Pincus Germany Private Equity VIII K.G. ("WPGPE" and together with WP VIII and
WPNPE I, the "Investors"), which shares the Reporting Persons may be deemed to
beneficially own.

Item 3.  Source and Amount of Funds or Other Consideration.

     Item 3 of the Amended 13D is hereby amended and restated in its entirety as
follows:

     The total amount of funds used by each Investor to purchase the securities
of the Company as described herein was furnished from the working capital of
such Investor. The total amount of funds used by the Investors to purchase the
securities of the Company as described herein was $155,120,066.94.




Item 4.  Purpose of Transaction.

         Item 4 of the Amended 13D is hereby amended by deleting all paragraphs
after the ninth paragraph thereof and inserting the following in place thereof:

     Pursuant to a Securities Purchase Agreement, dated May 5, 2005 (the
"Securities Purchase Agreement"), by and among WP VIII, WPNPE I, WPGPE
(hereinafter, collective referred to as the Warburg Pincus Entities") and the
Company, the Warburg Pincus Entities agreed to acquire from the Company (a) an
aggregate of 3,537,736 shares of Common Stock at a price per share equal to
$4.24, and for an aggregate purchase price of $15,000,000.64; and (b) warrants
to purchase an aggregate of 863,236 shares of Common Stock with an exercise
price of $5.00 (the "Securities Purchase Warrants"), and for an aggregate
purchase price of $107,904.50. Each of the Securities Purchase Warrants expires
at the earlier to occur of the fourth anniversary of the issuance of the
Securities Purchase Warrants or a "Change of Control" of the Company (as defined
in the Securities Purchase Warrants).

     Pursuant to an Amended and Restated Stockholders Agreement, dated as of May
9, 2005 (the "Stockholders Agreement"), by and between the Company and the
Investors, among other things, the holders of a majority in interest of the
Common Stock held by the Investors are entitled to designate two directors (the
"Warburg Pincus Designees") to the Company's Board of Directors (subject to
certain conditions). Under the Stockholders Agreement, any time that a Warburg
Pincus Designee is entitled to serve as a director of the Company, the Company
is obligated to take such actions as may be necessary to cause such Warburg
Pincus Designee to be appointed or elected to its Board of Directors.

                                       -2-


     Neither the Series B Preferred Stock, the Adjustable Warrant, the March 15
Warrants, the Securities Purchase Warrants nor the shares of Common Stock
issuable upon the conversion or exercise (as applicable) thereof are registered
under the Securities Act of 1933, as amended (the "Securities Act").
Accordingly, under the Stockholders Agreement, subject to certain conditions,
the Investors have the right to cause the Company to effect a registration under
the Securities Act with respect to any such shares of Common Stock, as well as
certain other shares of Common Stock that they may then hold.

     The Warburg Pincus Entities and the Company have entered into a Voting
Agreement, dated as of May 9, 2005 (the "Voting Agreement"), pursuant to which
the Warburg Pincus Entities have agreed that they will vote all of the shares of
Common Stock beneficially owned by them in favor of adoption of that certain
Agreement and Plan of Merger, dated as of May 9, 2005 (the "Merger Agreement"),
by and among the Company, Nova Acquisition Corporation ("Sub 1"), Nova
Acquisition LLC ("Sub 2") and Nova Inc. ("Nova"). Pursuant to the Merger
Agreement, upon satisfaction of the conditions set forth therein, Sub 1 will be
merged with and into Nova (the "First Step Merger"), with Nova as the surviving
corporation in the First Step Merger (the "Interim Surviving Corporation").
Thereafter, the Interim Surviving Corporation will be merged with and in to Sub
2 (the "Second Step Merger" and, taken together with the First Step Merger, the
"Merger"). Pursuant to the Voting Agreement, the Warburg Pincus Entities
appointed the Board of Directors of Nova as their attorney-in-fact and proxy,
with full power of substitution, to vote the shares of Common Stock beneficially
owned by them in favor of adoption of the Merger Agreement and against certain
other corporate actions.

                                      -3-


     Pursuant to a Stock Purchase Agreement, dated as of May 5, 2005 (the "Stock
Purchase Agreement"), by and among Warburg Pincus Entities and the Company, the
Warburg Pincus Entities agreed to acquire from the Company (a) an aggregate of
14,150,943 shares of Common Stock at a price per share equal to $4.24, and for
an aggregate purchase price of $59,999,998.32; and (b) warrants to purchase an
aggregate of 3,177,570 shares of Common Stock with an exercise price of $5.00
(the "Stock Purchase Warrants"). Each of the Stock Purchase Warrants expires
upon the earlier to occur of the fourth anniversary of the issuance of the Stock
Purchase Warrants or a "Change of Control" of the Company (as defined in the
Stock Purchase Warrants). On September 15, 2005, the transactions contemplated
by the Merger Agreement and the Stock Purchase Agreement were consummated and
the Company issued to the Investors the Stock Purchase Warrants and an aggregate
of 14,150,943 shares of Common Stock.

     The foregoing descriptions of the Securities Purchase Agreement, the
Securities Purchase Warrants, the Restated Stockholders Agreement and the Stock
Purchase Agreement are qualified in their entirety by reference to the
Securities Purchase Agreement, the Securities Purchase Warrants, the Restated
Stockholders Agreement, the Stock Purchase Agreement and the Commitment Letter,

securities of the Company, engage in discussions with the Company concerning
further acquisitions of securities of the Company or otherwise invest in the
Company or one or more of its subsidiaries. The Reporting Persons intend to
review their investment in the Company on a continuing basis and, depending upon
the price and availability of the Company's securities, subsequent developments
concerning the Company, the Company's business and prospects, other investment
and business opportunities available to the Reporting Persons, general stock
market and economic conditions, tax considerations and other factors considered
relevant, may decide at any time to increase or decrease the size of their
investment in the Company or to sell any or all of the securities of the Company
that they hold.

     Except as set for the above in this Item 4, none of the Reporting Persons
nor, to the best of their knowledge, any person listed in Schedule I to the
Original 13D, has any plans or proposals which relate to or would result in: (a)
the acquisition by any person of additional securities of the Company, or the
disposition of securities of the Company; (b) an extraordinary corporate
transaction, such as a merger, reorganization or

                                      -5-



liquidation, involving the Company or any of its subsidiaries; (c) a sale or
transfer of a material amount of assets of the Company or any of its
subsidiaries; (d) any change in the present Board of Directors or management of
the Company, including any plans or proposals to change the number or term of
directors or to fill any existing vacancies on the Board of Directors; (e) any
material change in the present capitalization or dividend policy of the Company;
(f) any other material change in the Company's business or corporate structure;
(g) changes in the Company's Charter, By-laws or instruments corresponding
thereto or other actions which may impede the acquisition of control of the
Company by any person; (h) causing a class of securities of the Company to be
de-listed from a national securities exchange or to cease to be authorized to be
quoted in an inter-dealer quotation system of a registered national securities
association; (i) a class of equity securities of the Company becoming eligible
for termination of registration pursuant to Section 12(g)(4) of the Exchange
Act; or (j) any action similar to any of those enumerated above.
