| ## 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. | |
