OpenVoice also achieves zero-shot cross-lingual voice cloning for languages not included in the massive-speaker training set. """ markdown_table = """

This online demo mainly supports English. The default style also supports Chinese. But OpenVoice can adapt to any other language as long as a base speaker is provided.
