Nuance Communications, Inc., the world's leading supplier of speech and imaging solutions, today announced that AT&T, the largest telecommunications company in the United States and one of the largest in the world, has selected speech technology from Nuance to automate its new 1-800-YellowPages (1-800-935-5697) Directory Assistance (DA) service. The Nuance solution is part of an integrated advertising platform from VoltDelta, a wholly owned subsidiary of Volt Information Sciences, Inc. (NYSE: VOL), which provides directory assistance, data management and operator services to telephone companies worldwide. AT&T began a controlled trial of this new DA service (www.att.com/1800YellowPages) in December 2006 in Bakersfield, Calif.; Oklahoma City, Okla.; and Columbus, Ohio. The new service provides free DA information accompanied by targeted advertising messages to the public.

AT&T will automate the white pages requests with speech recognition and text-to-speech solutions from Nuance, delivering instant access to extensive directory information without sacrificing customer service. Nuance participated in the development of a unique user interface customized for AT&T to make 1-800-YellowPages a differentiated and unique service while maximizing caller value and satisfaction, and enhancing speech recognition in the fulfillment of the caller's request.

VoltDelta is integrating Nuance's automated directory assistance application with VoltDelta's advertising platform, data, database services, and operator interfaces to provide a dynamic speech-enabled service for name and number search with operator back-up.

Nearly 50 billion directory searches are completed in the United States each year, according to industry research. Approximately six billion of these information requests are accessed through traditional directory assistance services, and the remainder are accessed via free services such as print directories or online searches.

"Consumers are looking for directory assistance when they don't have a phone book handy or can't jump online," said David Huntley, senior vice president-Diversified Businesses, AT&T. "In addition to our premier caller-paid Directory Assistance service, AT&T 1-800-YellowPages now offers our consumers audio YellowPages, powered by Nuance's speech technology. Nuance has been a critical player throughout the development of our new state-of-the-art advertiser supported Directory Assistance service."

"SpeechExpressSM DA Automation is a key component of VoltDelta's new integrated advertising solution for advertising-supported services," said Rich Oldach, executive vice president of strategic marketing at VoltDelta. "We have been integrating Nuance's advanced speech technologies and applications into our many SpeechExpress automation solutions for a broad range of automation solutions. We are excited to leverage our existing relationship with Nuance to offer cost-effective automation with operator back-up for services such as white pages searches for AT&T 1-800-YellowPages."

"The entrance of AT&T into the market for advertiser-supported DA services validates the business model of this evolving market," said Michael Thompson, vice president and general manager, telco, search and communications, Nuance. "We expect the number of free 411 calls to explode as callers discover the service offers a faster, more convenient alternative to other options such as standard yellow pages or traditional Internet searches" - Nuance.
