  Item 4.   Changes in Registrant's Certifying Accountant.
  
       On April 11, 2002, Nuance Communications, Inc. ("Nuance"), made a
  determination to no longer engage Arthur Andersen LLP ("Arthur Andersen") as its
  independent public accountants. Nuance's Board of Directors participated in and
  approved the decision to change principal accountants. On April 12, 2002, Nuance
  engaged Deloitte & Touche LLP to serve as its independent public accountants for
  the fiscal year ending December 31, 2002.
  
       Arthur Andersen's reports on Nuance's consolidated financial statements for
  each of the years ended December 31, 2001 and 2000 did not contain an adverse
  opinion or disclaimer of opinion, nor were they qualified or modified as to
  uncertainty, audit scope or accounting principles.
  
       During the years ended December 31, 2001 and 2000 and through the filing
  date of this Current Report on Form 8-K, there were no disagreements with Arthur
  Andersen on any matter of accounting principles or practices, financial
  statement disclosure, or auditing scope or procedure which, if not resolved to
  Arthur Andersen's satisfaction, would have caused it to make reference to the
  subject matter in connection with its report on Nuance's consolidated financial
  statements for such years; and there were no reportable events as specified in
  Item 304(a)(1)(v) of Regulation S-K.
  
       Nuance has provided Arthur Andersen with a copy of the foregoing
  disclosures. Attached as Exhibit 16.1 is a copy of Arthur Andersen's letter,
  dated April 15, 2002, stating its agreement with such statements.
  
       During the years ended December 31, 2001 and 2000 and until the engagement
  of Deloitte & Touche LLP, Nuance did not consult Deloitte & Touche LLP, with
  respect to the application of accounting principles to a specified transaction,
  either completed or proposed, or the type of audit opinion that might be
  rendered on Nuance's consolidated financial statements, or any other matters or
  reportable events as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.
  
  Item 7.   Financial Statements, Pro Forma Financial Information and Exhibits.
