WeNet语音识别调用通义千问

WeNet语音识别对通义千问（Qwen-72B-Chat Bot）调用，首先通过WeNet将用户的语音输入转录为文本，然后将此文本输入通用问答模型以获取答案。

连续对话

WeNet语音识别部分：使用WeNet库将录制的语音转换为文本。通过载入中文模型(chs_model)并使用其功能，对录制的语音进行转录处理。生成的文本作为用户输入被传递到下一步。

Qwen-72B-Chat Bot交互部分：利用Dashscope库实现与Qwen-72B-Chat Bot的交互。根据用户的文本输入与Chat Bot进行交互，发送用户输入的文本并接收Chat Bot的回复。这里的逻辑在model_chat函数中完成，通过Generation.call()函数向Chat Bot发送消息并获取回复。

Gradio界面设计： Gradio库用于创建用户界面，包括麦克风录音输入、文本框显示以及清除历史和设置系统功能的按钮。在界面设计中，使用了Microphone、Textbox、Button和Chatbot等组件，允许用户进行语音输入并查看对话的交互结果。

整个代码的目的是提供一个基于Gradio的界面，使用户能够通过语音与Qwen-72B-Chat Bot进行交互，并展示对话历史、系统状态等信息。

这样的集成将语音识别和聊天机器人交互结合在一起，为用户提供了一个使用简单且直观的界面，以便通过语音进行问题提问与回答。
