+1. 支持声音克隆
+2. 支持大模型对话
+3. 支持多种音频特征驱动：wav2vec、hubert
+4. 支持全身视频拼接

 ## 1. Installation
 
 Tested on Ubuntu 20.04, Python3.10, Pytorch 1.12 and CUDA 11.3

 ### 3.1 使用LLM模型进行数字人对话
 
 目前借鉴数字人对话系统[LinlyTalker](https://github.com/Kedreamix/Linly-Talker)的方式，LLM模型支持Chatgpt,Qwen和GeminiPro。需要在app.py中填入自己的api_key。
