OpenVoice is a cutting-edge AI voice cloning technology that provides versatile and high-quality voice synthesis capabilities. As detailed in its research paper, OpenVoice excels in three key areas:
- Accurate Tone Color Cloning: OpenVoice can precisely clone reference tone colors and generate speech in multiple languages and accents.
- Flexible Voice Style Control: Users gain granular control over voice styles, including emotion, accent, rhythm, pauses, and intonation.
- Zero-shot Cross-lingual Voice Cloning: It supports languages not included in the training dataset, making it highly adaptable.
In April 2024, OpenVoice V2 was released, enhancing the original version with better audio quality, native multilingual support (English, Spanish, French, Chinese, Japanese, Korean), and free commercial use under the MIT License. OpenVoice has been integral to MyShell.ai's instant voice cloning feature since May 2023, witnessing millions of global uses. Developed by researchers from MIT and Tsinghua University, OpenVoice is built on excellent projects like TTS, VITS, and VITS2, standing as a testament to collaborative innovation in AI voice technology.
