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
Time: 2022/03/06
Author: Xiaohong
功能:Python 更改目录下 目录及文件的 顺序命名
项目的文件结构方式:
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
本例为实验室产品,不具备直接使用，支持的语音录入长度也较短
主程序界面如下：
主程序 My_Audio_Record_cloud_class.py:
