AT&T Natural Voices™ Text-to-Speech Engine
AT&T Natural Voices: Always Innovating
From the first synthesized speech system in 1939 to today, AT&T has long been the world's speech technology pioneer, introducing the highest quality and most robust speech systems available anywhere. We're putting this expertise to work for businesses worldwide by integrating technologies, such as AT&T Natural Voices' Text-to-Speech (TTS) Engine - the most realistic, human-sounding synthetic speech system - into new and emerging AT&T business services.
AT&T Natural Voices™ Text-to-Speech Engine
AT&T continuously invests in innovative speech technologies so that businesses worldwide can optimize interactions and achieve a better Return on Communications in terms of reach and efficiency. Examples of applications and services being optimized by AT&T Natural Voices' TTS Engine today include an e-mail reader that provides e-mail access over the phone; a real-time notification and alerting service; a system that converts ASCII text messages into wav files for broadcast over local area networks; text readers that provide greater accessibility to any content on an individual's computer; a voice-enabled directory search engine; and a VoiceXML development gateway.
AT&T Natural Voices' TTS Engine can uniquely support the addition of many languages to any and all applications, including U.S. English, German, Latin American Spanish, U.K. English, Parisian French, and many more foreign languages to come - always with the highest standards of quality and intelligibility.
All editions of the TTS engine include both a female and male U.S. English voice and support SAPI 4.0, 5.0 and 5.1, the SSML component of VoiceXML, and JSAPI interface standards.
One TTS engine supports multiple languages. The AT&T Natural Voices Desktop Text-to-Speech Engine offers some enhanced pronunciation features; for example, when the engine reads "Dr. Smith lives on Ocean Dr.", it can determine that the first "Dr." should be pronounced "doctor" and the second "Dr." should be pronounced "drive". In addition, all of the names of the FORTUNE 500 companies, numerous business-related terms and the names of international currencies have near-perfect pronunciations.
AT&T Natural Voices' TTS Engine is tremendously flexible. It can pronounce words exactly the way you want it to. The engine includes language- and voice-specific custom dictionaries that enable users to define the pronunciation of certain words. Users can also determine how the engine reads certain acronyms and abbreviations, and change the speaking rate, volume and voice.
