程式功能: 用 UI 界面,点击界面上的“开始识别”来录音(调用百度云语音接口),并自动将结果显示在界面的文本框中

#功能:Python 更改目录下 目录及文件的 顺序命名
# 项目文件结构：
# 1. PyQt5 UI 文件: My_Audio_Record_cloud.ui
# 2. PyQt5 UI 文件转换生成的 PY 文件: My_Audio_Record_cloud_Ui.py
# 3. PyQt5 UI 文件对应的 Class 文件: My_Audio_Record_cloud_class.py
# 4. 通用的消息显示 文件(在My_Audio_Record_cloud_class.py 中被调用): FangMessage.py
# 这个例子是实验室产品，没有直接使用，支持的语音输入长度也短
主程序界面如下：
