About Tetyys TTS
Microsoft SAPI4 (Speech Application Programming Interface 4.0) was a groundbreaking text-to-speech technology released in the late 1990s. It introduced many of the iconic voices that became synonymous with early computer speech synthesis, including the famous Microsoft Sam voice.
Tetyys TTS preserves these classic voices by providing a modern web interface to the original SAPI4 engine. This service allows users to experience the nostalgic charm of retro computer voices while enjoying the convenience of a contemporary web application.
The service includes not only the standard Microsoft voices but also specialty voices like the RoboSoft series and the beloved BonziBUDDY voice, making it a comprehensive collection of early 2000s TTS technology.
Whether you're creating content for nostalgic purposes, educational projects, or just want to have fun with classic computer voices, Tetyys TTS provides an authentic experience with the original voice synthesis algorithms.
This service is maintained by the community and relies on donations to cover server costs. We're committed to preserving this piece of computing history for future generations to enjoy.
