文字转语音，导出音频mp3

 

用到的是Windows的SAPI，所以只支持Windows。

我测试了一百多个字符转音频导出，速度还挺快的，1秒不到就转好了。

// 正式代码

// 初始化
HRESULT hr = CoInitialize(NULL);
if (FAILED(hr))
{
    qDebug() << "init fail";
    return;
}

// 创建 ISpVoice
ISpVoice *pVoice;
hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **)&pVoice);
if (FAILED(hr))
{
    qDebug() << "create fail";
    CoUninitialize();
    return;
}


CComPtr<ISpStream> cpWavStream;
CComPtr<ISpStreamFormat> cpOldStream;
CSpStreamFormat OriginalFmt;
pVoice->GetOutputStream( &cpOldStream );
OriginalFmt.AssignFormat(cpOldStream);
hr = SPBindToFile( L"D:\\output.mp3",SPFM_CREATE_ALWAYS, &cpWavStream,&OriginalFmt.FormatId(), OriginalFmt.WaveFormatExPtr() );
if( SUCCEEDED( hr ) )
{
    pVoice->SetOutput(cpWavStream,TRUE);
    QString s = ui.textEdit->toPlainText();
    pVoice->Speak(s.toStdWString().c_str(), SPF_IS_XML, NULL);
    pVoice->Release();
    pVoice = NULL;
}
CoUninitialize();
