Hello World by Microsoft Speech SDK 5.1

    刚刚从 Microsoft 网站下栽了 Speech SDK 5.1 和中日文发声补丁，参考 Speech SDK文档写了几个小程序，尽管我也是刚刚接触 Speech若干小时的初学者，还是拿出来共享吧：

Speech SDK 采用 COM 的形式封装，和大多数COM对象一样，下面是一个似曾相识的初始化：

    CoInitialize(NULL);

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

    ISpVoice * pSpVoice = NULL;

    if (FAILED(CoCreateInstance(CLSID_SpVoice, NULL,

        CLSCTX_INPROC_SERVER, IID_ISpVoice, (void **)&pSpVoice)))

    {

        cout << "Failed to create instance of ISpVoice!" << endl;

        return -1;

    }

    现在我们用它来说 “Hello World”，非常简单：

pSpVoice->Speak(L"Hello World!", SPF_DEFAULT, NULL);

最后，清除这一切

pSpVoice->Release();

CoUninitialize();

很容易，是不是？下面我们稍微改变一下：

IEnumSpObjectTokens *pSpEnumTokens = NULL;

if (SUCCEEDED(SpEnumTokens(SPCAT_VOICES, L"language=409", NULL, &pSpEnumTokens)))

{

       ISpObjectToken *pSpToken = NULL;

       while (SUCCEEDED(pSpEnumTokens->Next(1, &pSpToken, NULL)) &&

              pSpToken != NULL)

       {

              pSpVoice->SetVoice(pSpToken);

              pSpVoice->Speak(L"Hello World!", SPF_DEFAULT, NULL);

              pSpToken->Release();

       }

       pSpEnumTokens->Release();

}

如果只需要一种 Voice，SpFindBestToken 更加方便：

ISpObjectToken * pSpObjectToken = NULL;

if (SUCCEEDED(SpFindBestToken(SPCAT_VOICES, L"gender=female",

       NULL, &pSpObjectToken)))

{

       pSpVoice->SetVoice(pSpObjectToken);

       pSpVoice->Speak(L"Hello World!", SPF_DEFAULT, NULL);

       pSpObjectToken->Release();

}

现在改为使用中文：
