OpenVoice is an open-source voice cloning tool developed by MyShell AI that can accurately clone reference tone colors and generate speech in multiple languages and accents. The tool has been in use since May 2023 and supports voice input in various languages.
Key Features of OpenVoice
OpenVoice V1
Accurate Tone Color Cloning
OpenVoice can precisely clone reference tone colors and generate speech in multiple languages and accents.
Flexible Voice Style Control
The tool allows for fine-grained control over voice styles, including emotion, accent, and other parameters such as rhythm, pauses, and intonation.
Zero-Shot Cross-Lingual Voice Cloning
The language of the generated speech and the reference speech do not need to be present in the large-scale multilingual training dataset.
OpenVoice V2 Updates
In April 2024, MyShell released OpenVoice V2, which includes all the features of V1 and the following improvements:
Enhanced Audio Quality
V2 adopts a different training strategy that delivers better audio quality.
Native Multilingual Support
OpenVoice V2 natively supports English, Spanish, French, Chinese, Japanese, and Korean.
Free for Commercial Use
Starting from April 2024, both V2 and V1 are released under the MIT license, allowing free use for commercial purposes.

What is OpenVoice and how does it function?
OpenVoice is an advanced, open-source AI voice cloning tool developed through collaboration between MIT, Tsinghua University, and MyShell. It functions by allowing users to input text or audio samples, which the AI processes to replicate the unique voice characteristics of a reference speaker. This technology enables realistic voice generation across various languages and styles. For more details, visit the official OpenVoice GitHub page.
Is OpenVoice completely free to use?
Yes, OpenVoice is entirely free as it is an open-source project. This means that anyone can access, modify, and utilize the tool without any associated costs. This accessibility makes it an attractive option for developers and content creators interested in exploring voice cloning technology. For more information, you can check the OpenVoice documentation.
What unique features does OpenVoice offer?
OpenVoice stands out due to its unique features, including accurate tone color cloning, granular control over voice styles, and the ability to perform cross-lingual voice cloning. Users can customize emotional tone, accent, and intonation, allowing for highly personalized voice outputs suitable for various applications. For a comprehensive overview of its capabilities, refer to the OpenVoice overview.
Are there ethical concerns associated with using OpenVoice?
Yes, ethical considerations are paramount when using voice cloning technologies like OpenVoice. Users must ensure they have consent from individuals whose voices are being cloned and should avoid using the technology for deceptive or harmful purposes. Responsible use is essential to maintain trust and integrity within the voice cloning community.
How can I start using OpenVoice effectively?
To get started with OpenVoice, visit the Hugging Face demo page, where you can interact with the model without needing to install any software. Simply input your text or upload an audio file, select a reference speaker, and generate the cloned voice. This user-friendly interface allows for immediate experimentation with the tool’s capabilities.
