运行web.py后，录制声音那个功能似乎不起作用+AI逆声效果不佳

**Summary[问题简述（一句话）]**
成功运行web.py，点击录制声音那个功能的麦克图标，好像录不了

**Env & To Reproduce[复现与环境]**
windows10，直接下载的.zip文件可能是最新版本、合成模型下载的是：pretrained-11-7-21_75k
让chatgpt写了一个简单的录音程序，然后录了一个5秒钟的声音，拟声后跟本人声音不是很像。是模型的原因吗？

Start by reproducing the microphone recording problem through web.py on Windows 10 using the downloaded ZIP and the pretrained-11-7-21_75k model. Confirm whether recording works and separately evaluate the reported voice-similarity issue; the report names no test or additional source file, so both symptoms need to be isolated before implementation.
