About Tts
Tts is an open source web app and PHP library for testing text-to-speech voices from several services. It is built with HTML5 and vanilla JavaScript, and requires PHP 8.0 or higher with Composer for full functionality. A Docker Compose file is included for setup.
You can enter text and hear how it sounds in different voices, including options from Amazon Polly via StreamElements and Streamlabs, Google Cloud Text-to-Speech, TikTok, IBM Watson, CereProc, and Cerence. The app lets you copy a link to the TTS audio for sharing, save generated audio locally for a set time, and build conversations with multiple voices as a playlist of clips.
It suits developers and Twitch streamers or viewers who want to preview how donation messages will sound, and anyone comparing TTS voices for test purposes. It is intended for testing only, not for professional or commercial use, and self-hosting on a web server is required.
