## Introduction



### OpenVoice V1



As we detailed in our [paper](https://arxiv.org/abs/2312.01479) and [website](https://research.myshell.ai/open-voice), 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 V2



In April 2024, we released OpenVoice V2, which includes all features in V1 and has:



**1. Better Audio Quality.**

OpenVoice V2 adopts a different training strategy that delivers better audio quality.



**2. Native Multi-lingual Support.**

English, Spanish, French, Chinese, Japanese and Korean are natively supported in OpenVoice V2.



**3. Free Commercial Use.**

Starting from April 2024, both V2 and V1 are released under MIT License. Free for commercial use.

OpenVoice has been powering the instant voice cloning capability of [myshell.ai](https://app.myshell.ai/explore) 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.
