What are Bark and GPT-SoVITS?
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
GPT-SoVITS
GPT-SoVITS is an open-source voice conversion and text-to-speech system capable of cloning a voice from a very short audio sample. It can be self-hosted with a web UI for training and generating speech in multiple languages.
- Few-shot voice cloning
- Multilingual synthesis
- Web training UI
- Runs locally
