Question 1

Accepted Answer

OpenVoice V2 is an open-source instant voice cloning model from MyShell, released in April 2024. It clones a speaker's tone color from a short clip and can speak multiple languages. See the official GitHub repository.

Accepted Answer

V2 natively supports English, Spanish, French, Chinese, Japanese, and Korean. Try it in the official Hugging Face demo.

Question 4

Does OpenVoice support voice conversion?

Accepted Answer

Yes. It uses a tone color converter that applies a reference speaker's tone color to generated or existing speech.

Question 5

What is zero-shot cross-lingual voice cloning?

Accepted Answer

It means the model can speak a language that does not appear in the reference clip or the training dataset while keeping the reference voice's tone color.

Question 6

How much audio do I need to clone a voice with OpenVoice?

Accepted Answer

OpenVoice is designed for instant cloning from a short audio clip. Cleaner reference audio generally gives better results.

Question 7

Do I need a GPU to run OpenVoice V2?

Accepted Answer

You can run it on a standard machine for experiments, but a GPU makes inference faster. Check the official repository for current requirements.

Question 8

Can I clone someone else's voice?

Accepted Answer

Only with their explicit permission. Using a cloned voice to impersonate or mislead people is unethical and may be illegal.
