TTS is just one of the projects at AT&T Labs – Research. Audio samples are for private, non-commercial use. Please be advised that differences may be noted between released NV products and the Research website demo. AT&T Natural Voices Text-to-Speech (TTS) Engines provide synthesis services in multiple languages for application builders creating desktop applications. The application requests services from the TTS engine using either a Microsoft SAPI 4 COM object, SAPI 5.1 COM object, a Java program, or using a convenient set of C APIs that are included with the product. High-quality male and female voices are included in 8 KHz µlaw and CCITT G.711 alaw for telephony applications. Additional voices and higher quality 16 KHz voices are available for non-telephony applications.
The Desktop Edition provides the same AT&T Natural
Voices TTS technology on a desktop computer but limits the TTS engine to a single channel.
