MEMORANDUM

TO:      SPEECHWORKS US EMPLOYEES

FROM:    SPEECHWORKS INTERNATIONAL, INC.

DATE:    MAY 30, 2003

SUBJECT: INFORMATION ABOUT YOUR OPTIONS AND RESULTING SHARES

First, thank you for your patience regarding your options. We know this is an
important topic for each of you. This memo outlines, among other things, the
option acceleration process for non-officer US employees under the terms of the
merger agreement with ScanSoft, Inc. PLEASE READ THIS MEMO CAREFULLY AND NOTE
THAT THE EXERCISE OF OPTIONS, AS MORE FULLY DESCRIBED BELOW, IS TIME SENSITIVE.
PLEASE NOTE THAT THIS MEMO DOES NOT DISCUSS ALL TAX CONSIDERATIONS THAT MAY BE
RELEVANT TO A PARTICULAR OPTIONHOLDER AND THEREFORE WE URGE YOU TO CONSULT YOUR
OWN TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES TO YOU OF THE MERGER,
INCLUDING ANY APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES.

SUMMARY OF OPTION TREATMENT

[ ]  You will have the benefit of 100% acceleration of all of your SpeechWorks
     options, regardless of the original vesting schedules and strike prices.

[ ]  Your options will become vested as of the second business day following the
     effective filing date of a Form S-4 Registration Statement (to be filed by
     ScanSoft) relating to the proposed merger with ScanSoft. We currently
     anticipate that the Registration Statement will be filed sometime in early
     June 2003.

[ ]  The reason we are treating options in this manner is that the acceleration
     of options under the terms of the merger agreement and the termination of
     any unexercised



     options following the closing will, among other things, eliminate the
     option overhang and ongoing compensation expense that would result from
     SpeechWorks options remaining outstanding and becoming ScanSoft options
     after the merger.

[ ]  You do not need to wait until your options are accelerated following the
     filing of the Registration Statement on Form S-4 to exercise options--under
     the terms of your option grant, you may exercise some or all of your
     currently vested options immediately. Whether or not options are
     "in-the-money" or "out-of-the-money" may vary day-to-day as the stock price
     changes.

[ ]  IF YOU DO NOT EXERCISE YOUR OPTIONS BY THE CLOSING OF THE MERGER
     (REGARDLESS OF WHETHER THEY ARE "IN-THE-MONEY" OR "OUT-OF-THE-MONEY"), THEY
     WILL TERMINATE. We currently anticipate that the merger will close sometime
     in August 2003, subject to the satisfaction or waiver of specified closing
     conditions.

[ ]  You should use your E*Trade account to track your options as described
     below.

EXERCISING OPTIONS; SELLING OR HOLDING SHARES

[ ]  You can exercise options through E*Trade in one of three ways: 1) a Cash
     Transaction by mailing a check to or wiring funds to your brokerage account
     at E*Trade; this leaves all your shares in your account; 2) a Sell-to-Cover
     Transaction is a cashless means of selling just the number of shares needed
     to cover your exercise price and any withholding taxes (if applicable),
     with the net number of shares remaining in your account; or 3) a
     Same-Day-Sale is a cashless means of exercising your options and selling
     all the resulting shares.

[ ]  You may sell any or all of your SpeechWorks shares - either right away in a
     same-day sale, at some later date for those remaining after a cash
     transaction or a sell-to-cover exercise, or those you already own outright
     from earlier exercises or purchases. On the other hand, YOU DO NOT HAVE TO
     SELL YOUR SHARES. Any SpeechWorks shares that you do not sell will be
     converted tax free (except for any cash received instead of a fractional
     share) into shares of ScanSoft common stock upon the closing of the merger.
     Please refer to the final joint proxy statement/prospectus for a more
     detailed description of the treatment of SpeechWorks common stock following
     the closing of the merger.

[ ]  There are tax implications of exercising options and of selling shares of
     SpeechWorks common stock. The number of shares you elect to sell or hold is
     up to you and should be based on your own personal investment goals and
     strategy, as well as your financial resources available to pay the option
     exercise price and any associated tax liabilities. You should consult with
     your own tax or financial advisor to determine the particular financial
     impact on you.

[ ]  We cannot determine the number of options that SpeechWorks employees, as
     well as officers and directors, will exercise and, with respect to shares
     of SpeechWorks common stock issued upon exercise, sell, prior to the
     closing of the merger. We expect, however, that all optionholders will
     exercise their in-the-money options prior to the closing of the merger and
     that many optionholders, including executive officers and directors, will
     elect to sell at least the portion of the shares issued upon exercise as is
     necessary to, among other things, pay the exercise price and any associated
     tax liabilities.

                                      -2-



[ ]  We suggest that you consider exercising your options now and determine
     whether to sell or hold the shares of SpeechWorks common stock that you
     receive upon exercise of the options. We do not believe it would be
     advantageous if all SpeechWorks optionholders waited until immediately
     prior to the closing of the merger to exercise their options and to sell
     shares in the marketplace in order to pay the exercise price and any tax
     liabilities associated with the exercise or to diversify.

PROCESS AND LOGISTICS

[ ]  You each have an E*Trade OptionsLink account and a linked Brokerage
     Account.

[ ]  If you have never accessed your OptionsLink account, you will receive an
     e-mail from E*Trade providing you with a direct link to your account, along
     with instructions for activation. If you are new to OptionsLink, please use
     that e-mail as your prompt to visit and activate your account.

[ ]  If you have any questions or problems, contact the E*Trade OptionsLink
     Customer Service department at 1-800-838-0908. To use this number you must
     have a user ID and a password. The easiest way to set that user ID and
     password is through the on-line activation process, so please visit the
     website via the link E*Trade e-mail to you before calling customer service.

[ ]  When you access your account, you will be able to see details of each grant
     you have received, including grant date and strike price.

[ ]  Options that are accelerated will appear in your E*Trade account as vested
     within a week or so after the acceleration date.

[ ]  You can initiate "sell-to-cover," "same day sale" and "exercise and hold"
     and certain other types of transactions on-line.

                        FREQUENTLY ASKED QUESTIONS (FAQS)

PLEASE NOTE THAT THIS MEMO DOES NOT DISCUSS ALL TAX CONSIDERATIONS THAT MAY BE
RELEVANT TO A PARTICULAR OPTIONHOLDER AND THEREFORE WE URGE YOU TO CONSULT YOUR
OWN TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES TO YOU OF THE MERGER,
INCLUDING ANY APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES.

     1. WHY ARE SPEECHWORKS OPTIONS BEING ACCELERATED AND THEN CANCELLED?

The acceleration of SpeechWorks options under the terms of the merger agreement
and the termination of any unexercised options following the closing will, among
other things, eliminate the option overhang and ongoing compensation expense
that would result from SpeechWorks options remaining outstanding as ScanSoft
options after the merger. You will have the benefit of 100% acceleration of all
of your SpeechWorks options, regardless of the original vesting schedules and
strike prices. However, to the extent not exercised prior to the closing of the
merger, each outstanding SpeechWorks option will be terminated and canceled upon
the closing of the merger.

In assessing the impact of this merger, you should consider the totality of the
transaction. Certain perceived negatives (e.g., terminating any out-of-the-money
options or
                                      -3-



unexercised in-the-money options) are balanced by other positives (e.g., 100%
acceleration).

We will describe in greater detail in the joint proxy statement/prospectus
(which forms a part of the Registration Statement on Form S-4 that is to be
filed by ScanSoft) the considerations we took into account in reaching our
decision to approve the terms of the merger, including the treatment of options.
We encourage all optionholders and stockholders to read the final joint proxy
statement/prospectus carefully once it is publicly available.

We currently anticipate that the Registration Statement will be filed sometime
in early June 2003.

2. WILL I RECEIVE SCANSOFT OPTIONS TO REPLACE OR MAKE UP FOR OPTIONS THAT ARE
TERMINATED?

As part of ScanSoft's total compensation program, it is ScanSoft's policy to
grant options to all employees in those locations where the legal and tax
restrictions are favorable to ScanSoft and to the employee. The number of
options ScanSoft would grant upon joining the combined company would not
correlate with the options being terminated but with ScanSoft's new hire option
guidelines. The size of the grant will be determined primarily by your position
with the combined company.

3. ARE THERE LIMITATIONS ON WHEN I CAN EXERCISE AND/OR SELL?

You can begin exercising and, if you elect, selling, now. You will not be
permitted to sell shares during the blackout period, which will be in effect for
the second fiscal quarter for non-officer employees from June 24, 2003 through
and including the first business day following our issuance of a press release
announcing SpeechWorks' earnings results for the fiscal quarter ending June 30,
2003. You may exercise options for cash during the blackout period, but you
cannot do a cashless exercise such as a sell-to-cover transaction. Of course,
you can never sell shares of SpeechWorks common stock if you are in possession
of material non-public information.

4. ARE THERE LIMITATIONS ON HOW MANY SHARES I CAN SELL?

As a non-officer employee, there are essentially no limitations on how many
shares of SpeechWorks common stock you can sell.

5. HOW WILL SELLING SPEECHWORKS COMMON STOCK AFFECT THE TRADING PRICE OF
   SPEECHWORKS COMMON STOCK?

We cannot predict the impact of employees (or any officers and directors)
selling on the trading price of SpeechWorks common stock. In general, we believe
that the trading price will be affected less if shares are sold over the next
several months. We suggest that you consider exercising your options now and
determine whether to sell or hold the shares of SpeechWorks common stock that
you receive upon exercise of the options.

                                      -4-




Remember, even though you must exercise your options (or the unexercised options
will be canceled), YOU DO NOT HAVE TO SELL YOUR SHARES. Any SpeechWorks shares
that you do not sell will be converted tax-free (except for any cash received
instead of a fractional share) into shares of ScanSoft common stock upon the
closing of the merger.

6. UNDERSTANDING OPTIONS: HOW ARE ISOS AND NQOS DIFFERENT?

ISOs. ISOs (incentive stock options) are options that offer the opportunity for
favorable tax treatment. You will not have income for regular federal income tax
purposes when you exercise an ISO. You may, however, be subject to the
Alternative Minimum Tax (AMT), described below.

You will have income if you sell stock acquired under an ISO at a profit (your
sales proceeds exceed your exercise price). The type of income will depend on
when you sell the stock. If you sell the stock more than two years after the
option was granted and more than one year after you exercised the option, then
all of your profit will be long-term capital gain. If you sell the stock prior
to satisfying these waiting periods, including in connection with a cashless
exercise or sell-to-cover transaction, then you will have made a "disqualifying
disposition" and a portion of your profit will be ordinary income and a portion
may be capital gain. Upon a disqualifying disposition, you will have
compensation income equal to the lesser of:

     --  the value of the stock on the day you exercised the option less your
         exercise price, and

     --  your profit.

If your profit exceeds the compensation income, then the excess profit will be
capital gain. This capital gain will be long-term if you have held the stock for
more than one year and otherwise will be short-term. The exchange of shares of
SpeechWorks common stock acquired upon exercise of an ISO for shares of ScanSoft
common stock in the merger will not be a disqualifying disposition and will not
otherwise be taxable (except for any cash received instead of a fractional
share) until you sell shares of ScanSoft common stock.

NQOs. You will have compensation income when you exercise a NQO (nonqualified
stock option) equal to the value of the stock on the day you exercised the
option less your exercise price. When you sell the stock, you will have capital
gain or loss equal to the difference between the sales proceeds and the value of
the stock on the day you exercised the option. This capital gain or loss will be
long-term if you have held the stock for more than one year and otherwise will
be short-term.

7. WHY ARE SOME OF MY OPTIONS IN OPTIONSLINK SHOWING UP SPLIT INTO ISOS AND
   NQOS? THE TOTAL LOOKS RIGHT, BUT NO ONE EVER TOLD ME I GOT SOME OF EACH.

The value of ISOs that first vest in any given year cannot exceed $100,000
(measured by fair market value at the grant date). If, when you received your
grant, the value of shares

                                      -5-


vesting in any one year (including any other options you had from earlier
grants) was over the $100,000 limit, the mix of options was automatically
adjusted so that the $100,000 limit was not exceeded and options for shares in
excess of the limit became NQOs.

8. DOES THE OPTION EXERCISE OR CASHLESS EXERCISE CHANGE THE TAX TREATMENT OF
   ISOS?

The acceleration in and of itself does not negate ISO status. The acceleration
of your options, coupled with other options already vesting in 2003, could put
you over the $100,000 annual limit described above. Also, doing a cashless
exercise such as a sell-to-cover transaction, or exercising ISOs and selling
shares within one year, would be a disqualifying disposition, and would negate
ISO treatment for those shares only.

9. DOES THIS CREATE AMT TAXES FOR ME?

The AMT (Alternative Minimum Tax) treatment of ISOs differs from their treatment
under the regular tax. You will have income for AMT purposes when you exercise
an ISO. In many cases, this income will require you to pay taxes even though you
have not sold the stock. In certain situations, you may be able to credit some
of the AMT you paid against your future regular taxes. The application of the
AMT and the use of any credit are complicated and depend upon your personal
circumstances. You should consult your own tax or financial advisor.

10. WHEN DO I HAVE TO PAY THE TAXES DUE ON THESE TRANSACTIONS?

Taxes are withheld by E*Trade and/or SpeechWorks upon your exercise of a NQO
(including an ISO treated as a NQO by reason of exceeding the $100,000 limit
discussed above).

Taxes you owe on your sale of shares, including ISO shares, are not withheld by
SpeechWorks, but rather are paid by you when you otherwise pay your taxes for
the year. Taxes arising out of the AMT are not subject to withholding. Sale
transactions could require you to make quarterly estimated tax payments above
and beyond your paycheck withholdings. You should consult your own tax or
financial advisor as to whether you will be required to make estimated payments.

                                       ***
