OpenVoice
Instant voice cloning with tone-color control — 38k stars, MIT.
About
OpenVoice (V2) is MyShell's voice-cloning system: clone any voice from a short audio clip and control emotion, accent, rhythm, and intonation via its tone-color converter — no massive training data per speaker. 37.9k stars, MIT. Staleness warning: last push April 2025 (18 months), 0 releases in 12 months — expect bitrot and prefer Fish Speech or XTTS v2 for new work. Included because the star count and MIT license keep it the most-forked cloning reference. Voice cloning carries misuse risk — use responsibly.
What it can do
- **Instant cloning**: short reference clip → cloned voice
- **Tone-color converter**: control emotion, accent, rhythm separately
- **Multilingual**: cross-lingual voice cloning
- **MIT licensed**: genuinely permissive
- **Reference implementation**: widely forked and studied
