+1. Index-TTS-vLLM是基于Index-TTS项目的vLLM推理服务，提供流式语音合成功能
+2. 支持多种音色，音质自然，适合各种语音交互场景
+3. 需要先部署Index-TTS-vLLM服务，然后配置API地址
+4. 支持实时流式合成，具有较低的延迟
+5. 支持自定义音色，可在项目assets文件夹下注册新音色
+部署步骤：
+1. 克隆项目：git clone https://github.com/Ksuriuri/index-tts-vllm.git
+2. 安装依赖：pip install -r requirements.txt
+3. 启动服务：python app.py
+4. 服务默认运行在 http://127.0.0.1:11996
+5. 如需其他音色，可到项目assets文件夹下注册
+6. 支持多种音频格式：pcm、wav、mp3等
+如需了解更多配置，请参考：https://github.com/Ksuriuri/index-tts-vllm/blob/master/README.md
