Chatterbox
An open-source text-to-speech model and tool from Resemble AI, notable for zero-shot voice cloning from a short sample and control over emotional expression. MIT licensed, so it is one of the few cloning-capable options you can use commercially.
Strengths
- Zero-shot voice cloning from only a few seconds of audio
- Control over emotion and expressiveness
- MIT licensed, unlike several cloning models restricted to non-commercial use
Weaknesses
- Wants a GPU for good speed, being larger than tiny TTS models
- Voice cloning carries real consent and ethics considerations
- Heavier to run than a lightweight engine like Piper or Kokoro
