2001年，AT&T展示了目前最先進的合成演說系統，AT&T Natural Voices。在這種技術的核心是AT&T Natural Voices Text-to-Speech (TTS) Engine，此引擎支持多國語言的男性與女性變音效果，包括美式英語，拉美西班牙語，德語，英式英語，巴黎式法語和加拿大式法語(並且這個列表在持續增長)。獨特的是，AT&T Natural Voices是定制的聲音形象 ，專有的聲音向商業提供一種快速和有效的方式來擴展企業的形象，商標和個性。

“該系統是目前世界上最接近人類語音的發音系統”(AT&T Labs公司)。該公司還表示，該系統同時也是全球第一個可以制作出所有聲音的產品。該系統還可以嵌入到手機中。

AT&T Labs Natural Voices Text-to-Speech由兩個部分組成。即由用來閱讀文本(text-to-speech)的引擎和聲音程序庫“Natural Voice fonts”所構成。前者為用自然的語調閱讀文本用的語音合成引擎。

而後者則具有可開發特定語音的功能。“例如可以合成使用某著名廣播員的聲音”(該公司)。

另外由於“人們可以通過自然的會話與電腦進行溝通”(AT&T Labs公司)，所以該系統還可以被用在呼叫中心、構築語音門戶網站的ASP(application service providers)，以及提供語音服務的VAR(value-added resellers)等用途

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 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.
