讓SAPI TTS說話字符串變量

Question

所以，我有一個程序，我使用SAPI這樣的：

ISpVoice * pVoice = NULL; 

if (FAILED(::CoInitialize(NULL))) 
{ 
    return FALSE; 
} 

HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void  **)&pVoice); 
if(SUCCEEDED(hr)) 
{ 
    hr = pVoice->Speak(L"I can talk!", SPF_IS_XML, NULL); 
} 

但是我要聲明一個變量，然後讓SAPI說出來。我怎麼做？

謝謝

使用std::wstring。假設您希望用戶輸入要說的內容（禁止文本框和按鈕）：

std::cout << "Enter lines of text to speak:\n"; 
for (std::wstring text; std::wcin >> text;) { 
    if (FAILED(hr = pVoice->Speak(text.c_str(), SPF_IS_XML, NULL))) { 
     std::cout << "Sorry, the text could not be spoken. The error code is " << hr << '\n'; 
    } 
}
