Openvoice

App in the BluixApps catalog

What it is

OpenVoice is MyShell's instant voice cloning model — clone any voice from a 6-second sample, generate speech in 17+ languages with that voice + custom emotion/accent/rhythm. The most flexible open voice clone with strong cross-lingual support.

When you need to control voice + style independently, OpenVoice is the most powerful open option.

  • Cross-lingual generation — clone English speaker, say in French / Chinese / Italian / etc.
  • Style transfer — change emotion, accent, rhythm independently of voice
  • Multi-lingual product demos — same voice, multiple languages
  • Character voices for games / animation
  • Branded TTS — your own voice → multilingual content

Who it's for
