📦 Installation

Clone and install

• Clone the repo

git clone --recursive https://github.com/FunAudioLLM/CosyVoice.git
# If you failed to clone submodule due to network failures, please run following command until success
cd CosyVoice
git submodule update --init --recursive

• Install Conda: please see https://docs.conda.io/en/latest/miniconda.html
• Create Conda env:

conda create -n cosyvoice python=3.10
conda activate cosyvoice
# pynini is required by WeTextProcessing, use conda to install it as it can be executed on all platform.
conda install -y -c conda - forge pynini==2.1.5
pip install -r requirements.txt -i https://mirrors.aliyun.com/pypi/simple/ --trusted - host=mirrors.aliyun.com

# If you encounter sox compatibility issues
# ubuntu
sudo apt - get install sox libsox - dev
# centos
sudo yum install sox sox - devel

Model download

We strongly recommend that you download our pretrained CosyVoice - 300M, CosyVoice - 300M - SFT, CosyVoice - 300M - Instruct model and CosyVoice - ttsfrd resource. If you are an expert in this field, and you are only interested in training your own CosyVoice model from scratch, you can skip this step.

# SDK model download
from modelscope import snapshot_download
snapshot_download('iic/CosyVoice2-0.5B', local_dir='pretrained_models/CosyVoice2-0.5B')
snapshot_download('iic/CosyVoice-300M', local_dir='pretrained_models/CosyVoice-300M')
snapshot_download('iic/CosyVoice-300M-25Hz', local_dir='pretrained_models/CosyVoice-300M-25Hz')
snapshot_download('iic/CosyVoice-300M-SFT', local_dir='pretrained_models/CosyVoice-300M-SFT')
snapshot_download('iic/CosyVoice-300M-Instruct', local_dir='pretrained_models/CosyVoice-300M-Instruct')
snapshot_download('iic/CosyVoice-ttsfrd', local_dir='pretrained_models/CosyVoice-ttsfrd')

# git model download, please ensure git lfs is installed
mkdir -p pretrained_models
git clone https://www.modelscope.cn/iic/CosyVoice2-0.5B.git pretrained_models/CosyVoice2-0.5B
git clone https://www.modelscope.cn/iic/CosyVoice-300M.git pretrained_models/CosyVoice-300M
git clone https://www.modelscope.cn/iic/CosyVoice-300M-25Hz.git pretrained_models/CosyVoice-300M-25Hz
git clone https://www.modelscope.cn/iic/CosyVoice-300M-SFT.git pretrained_models/CosyVoice-300M-SFT
git clone https://www.modelscope.cn/iic/CosyVoice-300M-Instruct.git pretrained_models/CosyVoice-300M-Instruct
git clone https://www.modelscope.cn/iic/CosyVoice-ttsfrd.git pretrained_models/CosyVoice-ttsfrd

Optionally, you can unzip ttsfrd resource and install ttsfrd package for better text normalization performance. Notice that this step is not necessary. If you do not install ttsfrd package, we will use WeTextProcessing by default.

cd pretrained_models/CosyVoice-ttsfrd/
unzip resource.zip -d .
pip install ttsfrd-0.3.6-cp38-cp38-linux_x86_64.whl

💻 Usage Examples

Basic Usage

For zero_shot/cross_lingual inference, please use CosyVoice2 - 0.5B or CosyVoice - 300M model. For sft inference, please use CosyVoice - 300M - SFT model. For instruct inference, please use CosyVoice - 300M - Instruct model. We strongly recommend using CosyVoice2 - 0.5B model for better streaming performance.

First, add third_party/Matcha - TTS to your PYTHONPATH.

export PYTHONPATH=third_party/Matcha-TTS

Start web demo

You can use our web demo page to get familiar with CosyVoice quickly. We support sft/zero_shot/cross_lingual/instruct inference in web demo. Please see the demo website for details.

# change iic/CosyVoice-300M-SFT for sft inference, or iic/CosyVoice-300M-Instruct for instruct inference
python3 webui.py --port 50000 --model_dir pretrained_models/CosyVoice-300M

Advanced Usage

For advanced users, we have provided train and inference scripts in examples/libritts/cosyvoice/run.sh. You can get familiar with CosyVoice following this recipe.

Build for deployment

Optionally, if you want to use grpc for service deployment, you can run following steps. Otherwise, you can just ignore this step.

cd runtime/python
docker build -t cosyvoice:v1.0 .
# change iic/CosyVoice-300M to iic/CosyVoice-300M-Instruct if you want to use instruct inference
# for grpc usage
docker run -d --runtime=nvidia -p 50000:50000 cosyvoice:v1.0 /bin/bash -c "cd /opt/CosyVoice/CosyVoice/runtime/python/grpc && python3 server.py --port 50000 --max_conc 4 --model_dir iic/CosyVoice-300M && sleep infinity"
cd grpc && python3 client.py --port 50000 --mode <sft|zero_shot|cross_lingual|instruct>
# for fastapi usage
docker run -d --runtime=nvidia -p 50000:50000 cosyvoice:v1.0 /bin/bash -c "cd /opt/CosyVoice/CosyVoice/runtime/python/fastapi && python3 server.py --port 50000 --model_dir iic/CosyVoice-300M && sleep infinity"
cd fastapi && python3 client.py --port 50000 --mode <sft|zero_shot|cross_lingual|instruct>
