What are Bark and Coqui TTS?
Bark
Bark is a generative text-to-audio model that produces realistic speech, music, and sound effects from text prompts. It can generate nonverbal sounds like laughing and supports many languages.
- Speech and sound generation
- Nonverbal expressions
- Multilingual output
- Music and effects
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
Bark vs Coqui TTS: key differences
Bark is written in Jupyter Notebook, while Coqui TTS is built with Python. Licensing differs — MIT for Bark versus MPL-2.0 for Coqui TTS.
