GPT-SoVITS

GPT-SoVITS TTS 服务部署说明。

采用gpt-sovits方案，bert-sovits适合长音频训练，gpt-sovits运行短音频快速推理

部署tts推理

git clone https://github.com/RVC-Boss/GPT-SoVITS.git

1. 安装依赖库

conda create -n sovits python=3.10
conda activate sovits
bash install.sh --download-uvr5 --device CU126 --source HF

2. 下载模型文件

第一步的安装脚本会自动下载模型文件
或者手动从 GPT-SoVITS Models 下载预训练模型，并将它们放置在 GPT_SoVITS/GPT_SoVITS/pretrained_models 中

最终文件目录如下（文件名可能有更新）

pretrained_models/
    --chinese-hubert-base
    --chinese-roberta-wwm-ext-large
    --gsv-v2final-pretrained
    s1bert25hz-2kh-longer-epoch=68e-step=50232.ckpt
    s2D488k.pth
    s2G488k.pth

3. 启动api服务

python api_v2.py

如果有错误提示找不到cmudict

import nltk
nltk.download('cmudict')

4. 接口说明
