Here are the relevant links: https://huggingface.co/myshell-ai/OpenVoiceV2 https://github.com/myshell-ai/OpenVoice

For some reason, the model weights for V2 are not directly downloadable from their source, But a copy is found here: https://huggingface.co/kevinwang676/OpenVoice-v2/tree/main

OpenVoice V2, is currently the most accurate Open Source voice cloning model, so i would highly recommend it.

Thanks for this discovery. Looks like something that can be easily integrated with Speech Note :)
