In the ever-evolving world of voice technology, OpenVoice stands as a game-changer.

This groundbreaking platform, developed by a team of experts from MIT, Tsinghua University, and MyShell, offers a trifecta of advantages: precise tone color cloning, fine-grained voice style control, and zero-shot cross-lingual capabilities.

Since its launch in May 2023, OpenVoice has witnessed explosive growth, powering MyShell’s instant voice cloning capability and reshaping the future of voice cloning technology.

As we detailed in our paper and website, the advantages of OpenVoice are three-fold:

1. Accurate Tone Color Cloning. OpenVoice can accurately clone the reference tone color and generate speech in multiple languages and accents.

2. Flexible Voice Style Control. OpenVoice enables granular control over voice styles, such as emotion and accent, as well as other style parameters including rhythm, pauses, and intonation.

3. Zero-shot Cross-lingual Voice Cloning. Neither of the language of the generated speech nor the language of the reference speech needs to be presented in the massive-speaker multi-lingual training dataset.

OpenVoice has been powering the instant voice cloning capability of since May 2023. Until Nov 2023, the voice cloning model has been used tens of millions of times by users worldwide, and witnessed the explosive user growth on the platform.
