+## 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.
