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：

ISpObjectToken * pSpObjectToken = NULL;

if (SUCCEEDED(SpFindBestToken(SPCAT_VOICES, L"language=804",

NULL, &pSpObjectToken)))

{

pSpVoice->SetVoice(pSpObjectToken);

pSpVoice->Speak(L"世界你好！", SPF_DEFAULT, NULL);

pSpObjectToken->Release();

}

ISpVoice::Speak 可以允许朗读的句子中包含 XML 标记，其实以上这一切用 XML 标记将变得十分简单：

pSpVoice->Speak(L"<lang langid=\"804\">世界你好！</lang>", SPF_DEFAULT, NULL);

pSpVoice->Speak(L"<voice required=\"gender=female\">Hello World!</voice>", SPF_DEFAULT, NULL);

最后，以一段简单的报时结束这篇文章：

SYSTEMTIME st;

GetLocalTime(&st);

ISpObjectToken * pSpObjectToken = NULL;

if (SUCCEEDED(SpFindBestToken(SPCAT_VOICES, L"language=804", NULL, &pSpObjectToken)))

{

pSpVoice->SetVoice(pSpObjectToken);

WCHAR wsz[128];

swprintf(wsz,

L"现在是<context ID = \"CHS_Date_ymdhm\">%.4d-%.02d-%.2d %.2d:%.02d</context>",

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

pSpVoice->Speak(wsz, SPF_IS_XML, NULL);

pSpObjectToken->Release();

}

■ 到此为止，希望这篇文章能带给初学者一点启发。
