BURLINGTON, Mass., April 28, 2008 – Nuance Communications, Inc. (NASDAQ: NUAN), a leading provider of speech and imaging solutions, today announced that Avaya Inc., a leading global provider of business communications applications, systems and services, has selected speech solutions from Nuance to enhance the employee productivity and collaboration options of its unified communications offering.

As part of the agreement, Nuance speech recognition will ship as a standard component of Avaya Modular Messaging 4.0, with the inclusion of Avaya one-X® Speech. Avaya one-X Speech is a “hands-free” user interface enabling users to access, interact with and manage email and voice mail, tasks and calendaring, and calling and conferencing capabilities – all via speech commands from any telephone.

“Avaya Unified Communications gives workers the right tool for the right job, so the user interface has to be easy-to-use and provide seamless access,” said Mary Dunlop, vice president, Unified Communications Product Management. “Nuance’s speech recognition technologies are acutely attuned to the natural way of speaking, which allows mobile workers comfortably interact with communications and productivity tools even when they can’t get connected by any other means.”

“We’ve worked with Avaya for quite some time to develop a flexible, powerful speech solution to improve responsiveness and enable workers to be effective anywhere,” said Michael Thompson, general manager, mobile search, messaging and handsets, Nuance. “Simple and intuitive speech commands create a natural user interface so that employees will spend less time managing communications and more time communicating.”
