目标：
1.学习使用百度AI开放平台进行语音识别与语音合成
百度AI有两种开发方式：REST, SDK; 本文使用的是SDK python进行开发
文档地址：https://ai.baidu.com/docs#/OCR-Python-SDK/53932383
2.将学到的内容：多线程，字符串转变为字典的方法
3.生成exe格式可执行文件
pyinstaller -F xxx.py 参考文档 https://blog.csdn.net/qq_35203425/article/details/78568141
4.python-Tkinter图形界面开发
1.单选按钮控件 Radiobutton 2.多选框按钮Checkbutton
问题点：
1.界面上的模块不会随窗口放大产生变化
2.未添加异常捕获
界面：
