What are Coqui TTS and OpenVoice?
Coqui TTS
Coqui TTS is a library and toolkit for advanced text-to-speech generation, including voice cloning with the XTTS model. It supports many languages and pretrained voices for fully local speech synthesis.
- Multilingual synthesis
- XTTS voice cloning
- Many pretrained models
- Trainable on custom data
OpenVoice
OpenVoice is a voice cloning approach that replicates a speaker's voice from a short reference clip and generates speech in multiple languages. It allows control over emotion, accent, and other style parameters.
- Instant voice cloning
- Cross-lingual synthesis
- Style and emotion control
- Short reference clips
Coqui TTS vs OpenVoice: key differences
Both projects are written in Python. Licensing differs — MPL-2.0 for Coqui TTS versus MIT for OpenVoice. Coqui TTS is the more established project (first released 2021), while OpenVoice arrived in 2023. Coqui TTS lists first-class Docker deployment; OpenVoice does not.
