## Linux Install

This section is only for developers and researchers who are familiar with Linux, Python and PyTorch. Clone this repo, and run

```
conda create -n openvoice python=3.9
conda activate openvoice
git clone git@github.com:myshell-ai/OpenVoice.git
cd OpenVoice
pip install -e .
```

No matter if you are using V1 or V2, the above installation is the same.

### OpenVoice V1

Download the checkpoint from [here](https://myshell-public-repo-hosting.s3.amazonaws.com/openvoice/checkpoints_1226.zip) and extract it to the `checkpoints` folder.

**1. Flexible Voice Style Control.**
Please see [`demo_part1.ipynb`](../demo_part1.ipynb) for an example usage of how OpenVoice enables flexible style control over the cloned voice.

**2. Cross-Lingual Voice Cloning.**
Please see [`demo_part2.ipynb`](../demo_part2.ipynb) for an example for languages seen or unseen in the MSML training set.

**3. Gradio Demo.**. We provide a minimalist local gradio demo here. We strongly suggest the users to look into `demo_part1.ipynb`, `demo_part2.ipynb` and the [QnA](QA.md) if they run into issues with the gradio demo. Launch a local gradio demo with `python -m openvoice_app --share`.

### OpenVoice V2

Download the checkpoint from [here](https://myshell-public-repo-hosting.s3.amazonaws.com/openvoice/checkpoints_v2_0417.zip) and extract it to the `checkpoints_v2` folder.

Install [MeloTTS](https://github.com/myshell-ai/MeloTTS):
```
pip install git+https://github.com/myshell-ai/MeloTTS.git
python -m unidic download
```

**Demo Usage.** Please see [`demo_part3.ipynb`](../demo_part3.ipynb) for example usage of OpenVoice V2. Now it natively supports English, Spanish, French, Chinese, Japanese and Korean.
