ChatTTS（Chat Text To Speech），专为对话场景设计的文本生成语音(TTS)模型，适用于大型语言模型(LLM)助手的对话任务，以及诸如对话式音频和视频介绍等应用。支持中文和英文，还可以穿插笑声、说话间的停顿、以及语气词等。

1 下载模型

通过git-lfs工具包下载：

sudo apt install git-lfs

下载文件：

git lfs install
git clone https://www.modelscope.cn/pzc163/chatTTS.git ChatTTS-Model

如果因网络不佳下载中断，可以通过以下命令在中断后继续下载：

git lfs pull

2 安装 ChatTTS 依赖包

下载ChatTTS官网GitHub源码：

git clone https://gitcode.com/2noise/ChatTTS.git ChatTTS

安装Python依赖包:

cd ChatTTS
pip install -r requirements.txt

torch需要使用2.2.2

3 ChatTTS 中文文本转音频文件

ChatTTS 官网的样例代码 API 可能会跑不起来。

ChatTTS-01.py

import ChatTTS
import torch
import torchaudio# 下载的ChatTTS模型文件目录，请按照实际情况替换
MODEL_PATH = '/path/to/ChatTTS-Model'# 初始化并加载模型，特别注意加载模型参数，官网样例代码已经过时
chat = ChatTTS.Chat()
chat.load_models(vocos_config_path=f'{MODEL_PATH}/config/vocos.yaml',vocos_ckpt_path=f'{MODEL_PATH}/asset/Vocos.pt',gpt_config_path=f'{MODEL_PATH}/config/gpt.yaml',gpt_ckpt_path=f'{MODEL_PATH}/asset/GPT.pt',decoder_config_path=f'{MODEL_PATH}/config/decoder.yaml',decoder_ckpt_path=f'{MODEL_PATH}/asset/Decoder.pt',tokenizer_path=f'{MODEL_PATH}/asset/tokenizer.pt',
)# 需要转化为音频的文本内容
text = '中文文本'# 文本转为音频
wavs = chat.infer(text, use_decoder=True)# 保存音频文件到本地文件（采样率为24000Hz）
torchaudio.save("./output/output-01.wav", torch.from_numpy(wavs[0]), 24000)

运行Python代码：python ChatTTS-01.py

也可以在文本转换成语音之后，直接播放语音内容：

from IPython.display import Audio# 播放生成的音频（autoplay=True 代表自动播放）
Audio(wavs[0], rate=24000, autoplay=True)

4 搭建 WebUI 界面

4.1 安装 Python 依赖包

pip install omegaconf~=2.3.0 transformers~=4.41.1
pip install tqdm einops vector_quantize_pytorch vocos
pip install modelscope gradio

运行 Python 程序，即可看到可视化界面，可以随意输入文本来生成音频文件了。
