# \* OpenVoice: Open Source Voice Cloning

OpenVoice, is a collaborative effort by MIT, Tsinghua University, and Canadian AI startup MyShell. It is an open-source alternative for voice cloning. This platform boasts near-instant cloning capabilities and detailed control features that surpass existing technologies.

Open-sourced, meaning its code is publicly available for anyone to use and modify.

&#x20;We introduce OpenVoice, a versatile instant voice cloning approach that requires only a short audio clip from the reference speaker to replicate their voice and generate speech in multiple languages.&#x20;

OpenVoice enables granular control over voice styles, including **emotion, accent, rhythm, pauses, and intonation,** in addition to replicating the tone color of the reference speaker.&#x20;

OpenVoice also achieves zero-shot cross-lingual voice cloning for languages not included in the massive-speaker training set.&#x20;

OpenVoice is also computationally efficient, costing tens of times less than commercially available APIs that offer even inferior performance.&#x20;

### Accurate Tone Color Cloning&#x20;

OpenVoice can accurately clone the reference tone color and generate speech in multiple languages and accents.

### Flexible Voice Style Control&#x20;

OpenVoice enables granular control over voice styles, such as emotion and accent, as well as other style parameters including rhythm, pauses, and intonation. Here we demonstrate the control over emotion and accent of the generated voice.

### Zero-shot Cross-lingual Voice Cloning&#x20;

The reference voice and the generated voice can be in any languages outside the massive-speaker multi-lingual dataset. We use “U” to denote the unseen languages in the following examples.
