OpenTTS

What is OpenTTS[edit | edit source]

OpenTTS is a collection of Docker images (one per language) with many open source text to speech engines and voices.

Every text to speech engine and voice is available through a single HTTP API
A MaryTTS-compatible HTTP API is available, allowing OpenTTS to be used without custom plugins in Home Assistant, etc.
Basic SSML support allows mixing multiple voices with custom silence breaks and word pronunciations
