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.

AdvantagesOpenTTS[edit | edit source]

  • 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
