/初始化语音 +void RecoEvent();/识别命令函数 +BOOL b_initSR; +BOOL b_Cmd_Grammar; /3个语音接口 +CComPtr m_cpRecocontxt; +CComPtr m_cpRecoGrammar; +CComPtr m_cpRecoEngine; 然后开始添加语音类，需要注意的是在定义语音类的头文件中，包含sphelper.h并且自定义语音识别消息和类型 #define GID_CMD_GR 333333 #define WM_RECOEVENT WM_USER+102 剩下来就是对cpp文件的函数initSR()和RecoEvent()补充函数体 3）具体见下面代码： （1）void CSpeech:initSR() HRESULT hr=S_OK;
