微软TTS语音windows speech SDK使用方法

windows7以后系统自带TTS，windows speech SDK，只需要包含头文件，使用起来就可以。

使用中遇到char转换wchar的问题，也是最终搞定了。示例如下：

 

#include 
#include 

bool isCreatWavFile = FALSE;//是否创建.wav音频文件
int main()
{
	ISpVoice *pVoice = NULL;
	if (FAILED(::CoInitialize(NULL)))
		return FALSE;
	HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **)&pVoice);
	char szStr[30] = "";
	sprintf(szStr, "我今天%d了", 18);
	WCHAR wszClassName[50];
	if (SUCCEEDED(hr))
	{
		//如果生成音频文件，在WTX[]中输入音频文本内容
		if (isCreatWavFile)
		{
			CComPtr  cpWavStream;
			CComPtr  cpOldStream;
			CSpStreamFormat originalFmt;
			pVoice->GetOutputStream(&cpOldStream);
			originalFmt.AssignFormat(cpOldStream);
			hr = SPBindToFile(L"d:\\output.wav", SPFM_CREATE_ALWAYS, &cpWavStream, &originalFmt.FormatId(), originalFmt.WaveFormatExPtr());
			if (SUCCEEDED(hr))
			{
				pVoice->SetOutput(cpWavStream, TRUE);
				WCHAR WTX[] = L"凡事何必都看淡，自己理解就很好";
				//pVoice->Speak(WTX, SPF_IS_XML, NULL);
				pVoice->Speak(WTX, 0, NULL);
				pVoice->Release();
				pVoice = NULL;
			}
		}
		else
		{
			MultiByteToWideChar(CP_OEMCP, 0, szStr, strlen(szStr) + 1, wszClassName, 50);

			hr = pVoice->Speak(wszClassName, 0, NULL);
			pVoice->Release();
			pVoice = NULL;
		}
	}
	::CoUninitialize();
	return 0;
}
