c++ - 使 SAPI TTS 说出字符串变量

Question

所以，我有一个使用 SAPI 的程序，如下所示：

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);
}

但我想声明一个变量，然后让 sapi 说出它们。我怎么做？

谢谢

使用std::wstring. 假设您希望用户输入要说的内容（除了文本框和按钮）：

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';
    }
}
