What it is

OpenVoice is MyShell's open-source TTS model with explicit tone-color cloning and style controls. V1 is MIT-licensed; V2 added cross-lingual cloning across 6+ languages. Used widely as a free alternative to XTTS. Consent posture: open weights — operator-side enforcement.

Best for: Self-hosters needing voice cloning with cross-lingual style transfer under a permissive license.
Watch out for: Output quality below XTTS / ElevenLabs on long-form prosody; V1 is MIT, V2 weights have a separate license.
