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/X-T-E-R/GPT-SoVITS-Inference.git

1. 安装依赖库

conda create -n GPTSoVits python=3.9
conda activate GPTSoVits
bash install.sh

从 GPT-SoVITS Models 下载预训练模型，并将它们放置在 GPT_SoVITS\pretrained_models 中

2. Model Folder Format

模型文件下载地址 https://www.yuque.com/xter/zibxlp/gsximn7ditzgispg
下载的模型文件放到trained目录下, 如 trained/Character1/
Put the pth / ckpt / wav files in it, the wav should be named as the prompt text
Like :

trained
--hutao
----hutao-e75.ckpt
----hutao_e60_s3360.pth
----hutao said something.wav

3. 启动

3.1 后端服务:

python Inference/src/tts_backend.py
如果有错误提示找不到cmudict，从这下载https://github.com/nltk/nltk_data，将packages改名为nltk_data放到home目录下

3.2 管理character:

python Inference/src/Character_Manager.py
浏览器打开可以管理character和emotion

3.3 测试tts功能:

python Inference/src/TTS_Webui.py

4. 接口说明

4.1 Character and Emotion List

To obtain the supported characters and their corresponding emotions, please visit the following URL:

• URL: http://127.0.0.1:5000/character_list
• Returns: A JSON format list of characters and corresponding emotions
• Method: GET

{
    "Hanabi": [
        "default",
        "Normal",
        "Yandere",
    ],
    "Hutao": [
        "default"
    ]
}

4.2 Text-to-Speech

• URL: http://127.0.0.1:5000/tts
• Returns: Audio on success. Error message on failure.
• Method: GET/POST

{
    "method": "POST",
    "body": {
        "character": "${chaName}",
        "emotion": "${Emotion}",
        "text": "${speakText}",
        "text_language": "${textLanguage}",
        "batch_size": ${batch_size},
        "speed": ${speed},
        "top_k": ${topK},
        "top_p": ${topP},
        "temperature": ${temperature},
        "stream": "${stream}",
        "format": "${Format}",
        "save_temp": "${saveTemp}"
    }
}

Parameter Explanation

• text: The text to be converted, URL encoding is recommended.

• character: Character folder name, pay attention to case sensitivity, full/half width, and language.

• emotion: Character emotion, must be an actually supported emotion of the character, otherwise, the default emotion will be used.

• text_language: Text language (auto / zh / en / ja), default is multilingual mixed.

• top_k, top_p, temperature: GPT model parameters, no need to modify if unfamiliar.

• batch_size: How many batches at a time, can be increased for faster processing if you have a powerful computer, integer, default is 1.

• speed: Speech speed, default is 1.0.

• save_temp: Whether to save temporary files, when true, the backend will save the generated audio, and subsequent identical requests will directly return that data, default is false.

• stream: Whether to stream, when true, audio will be returned sentence by sentence, default is false.

• format: Format, default is WAV, allows MP3/ WAV/ OGG.
