如何用vc++开发语音识别应用，包括VS008升级报错问题，不要VC6.0的

	CLSID CLSID_SpVoice;    // class ID for the SAPI SpVoice object

	LPDISPATCH pDisp;       // dispatch interface for the class

	ISpeechVoice voice;     // use the MFC Class Wizard generated wrapper

	

	ISpeechObjectTokens voiceList;

	ISpeechObjectToken recoObject;

	CLSIDFromProgID(L"SAPI.SpVoice", &CLSID_SpVoice);

	voice.CreateDispatch(CLSID_SpVoice); 

	pDisp = voice.m_lpDispatch; 

	

	HRESULT hr = pDisp->QueryInterface(CLSID_SpVoice, (void**)&voice.m_lpDispatch); 

	

	if (hr == S_OK) 

	{ 

		pDisp->Release(); 

	} 

	else 

	{ 

		voice.AttachDispatch(pDisp, TRUE); 

	}

	voice.SetRate(0);

	

	voice.SetVolume(100);

	SYSTEMTIME st;

	GetLocalTime(&st);

	

	CString str;

	str.Format("<lang langid=\"804\">现在是<context ID = \"CHS_Date_ymdhm\">%.4d-%.02d-%.2d %.2d:%.02d</context></lang>", 

			   st.wYear, st.wMonth, st.wDay, st.wHour, st.wMinute);



	



	voice.Speak("<lang langid=\"804\">xx你好！</lang>", 1);

	voice.Speak(str, 1);
