OpenVoice v2

MIT

Tone-color cloning + cross-lingual transfer

OpenVoice v2 clones the tone color of a reference speaker and then lets you control style — emotion, accent, rhythm, pauses, intonation — independently. It supports cross-lingual cloning into languages the reference speaker never spoke, and v2 moved to a permissive MIT license.
