此博客展示了一段C++代码，利用Microsoft语音API将文本转换为语音并保存为WAV文件。代码包含COM初始化、获取ISpVoice接口、绑定输出文件等步骤，还使用了XML格式指定语音。

//text_to_wave.CPP

#include <sapi.h>
#include <sphelper.h>

#pragma comment(lib,"ole32.lib")
#pragma comment(lib,"sapi.lib")

int main(int argc, char* argv[])
{
ISpVoice * pVoice = NULL;
//COM初始化：
if (FAILED(::CoInitialize(NULL)))
 return FALSE;

//获取ISpVoice：
HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL,
 IID_ISpVoice, (void **)&pVoice);
if( SUCCEEDED( hr ) )
{
 CComPtr<ISpStream> cpWavStream;
 CComPtr<ISpStreamFormat> cpOldStream;
 CSpStreamFormat OriginalFmt;
 pVoice->GetOutputStream( &cpOldStream );
 OriginalFmt.AssignFormat(cpOldStream);

 //绑定文件：
 hr = SPBindToFile( L"D://output.wav",SPFM_CREATE_ALWAYS,
 &cpWavStream,&OriginalFmt.FormatId(),
 OriginalFmt.WaveFormatExPtr() );

if( SUCCEEDED( hr ) )
 {
 pVoice->SetOutput(cpWavStream,TRUE);
 WCHAR WTX[] = L"<VOICE REQUIRED='NAME=Microsoft Mary'/>text to wave";
 pVoice->Speak(WTX, SPF_IS_XML, NULL);
 pVoice->Release();
 pVoice = NULL;
 }
}

//释放COM资源：
::CoUninitialize();
return TRUE;
}
