# OpenVoice

> OpenVoice clones a reference voice's tone colour and speaks it in other languages; V2 (April 2024) natively supports English, Spanish, French, Chinese, Japanese and Korean and uses MeloTTS (MIT) as the base speaker. Code and V1/V2 weights are MIT and the README states free commercial use. Official install is Linux only (conda, manual checkpoint download); Windows and Docker guides are community-contributed. No hardware requirements are documented. Last push April 2025.
