我的项目需要
- 在命令行窗口运行；
- 程序运行时，会让你输出一句英语，而后你须要对着麦克风读出这句英语；
- 程序会判断你读的对不对，如果不对会让你重读，直到读对为止；
- 应用百度云语音辨认：https://ai.baidu.com/tech/spe...
Python编程知识点
- while循环
- 用户输出字符串
- 字符串小写
- 条件判断
- 自定义函数
- 异样解决
- SpeechRecognition 模块 (装置：
pip install SpeechRecognition) - pyaudio 模块 (装置：
pip install pyaudio) - baidu-aip 模块(装置：
pip install baidu-aip)
参考代码
