SAPI:应用程序不说话

SAPI: Application is not speaking

本文关键字：不说 应用程序 SAPI      更新时间：2023-10-16

请看下面的代码

main.cpp 

    #define _ATL_APARTMENT_THREADED
#include <atlbase.h>
//You may derive a class from CComModule and use it if you want to override something,
//but do not change the name of _Module
extern CComModule _Module;
#include <atlcom.h>
#include <sapi.h>
#include <iostream>
using namespace std;
int main(int argc, char* argv[])
{
    cout << "Hello" << endl;
    ISpVoice * pVoice = NULL;
    if (FAILED(::CoInitialize(NULL)))
        return FALSE;
    HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **)&pVoice);
    if( SUCCEEDED( hr ) )
    {
        cout << "Succeeded" << endl;
        hr = pVoice->Speak(L"Hello world", 0, NULL);
        pVoice->Release();
        pVoice = NULL;
    }
    else
    {
        cout << "Not succeeded" << endl;
    }
    ::CoUninitialize();
    return TRUE;
}

当我运行这段代码时，窗口打开，打印"Hello"消息。但是一点声音也没有!它应该说"你好，世界"!为什么会这样?

以下是QT .pro设置，以防需要

在调用pVoice->Speak(L"Hello world", 0, NULL)时尝试使用SPF_ASYNC代替0。
我是这样做的:

[...]   
HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, reinterpret_cast<void**>(&pVoice));
if( SUCCEEDED( hr ) )
{        
    const wchar_t* reqAttributs = L"Language=409"; // 409 = en_US; 809 = en_UK; 40C = fr_FR
    const wchar_t* optAttributs = L"Gender=Female"; // or L"Gender=Male"
    ISpObjectToken* cpTokenEng;
    if (FAILED(::SpFindBestToken(SPCAT_VOICES, reqAttributs, optAttributs, &cpTokenEng))) {
        throw std::exception("Couldn't find a Token with the required attributs.");
    }
    pVoice->SetVoice(cpTokenEng);
    hr = pVoice->Speak(L"Hello World", SPF_ASYNC, nullptr);
        if (hr == S_OK) {
            // OK
        } else if (hr == E_INVALIDARG) {
            // One or more parameters are invalid
        } else if (hr == E_POINTER) {
            // Invalid pointer
        } else if (hr == E_OUTOFMEMORY) {
            // Exceeded available memory
        } else {
            // Unknown error
        }
        hr = pVoice->WaitUntilDone(INFINITE);
        pVoice->Release();
        pVoice = nullptr;
}
[...]

Token部分不是真正必要的，但如果您想自定义声音(必须在计算机上安装多个声音以获得最佳效果)，它可能很有用。

在演讲有时间结束之前，您正在调用pVoice对象的Release。API有一个waitUntilDone函数，在释放对象之前可能需要它。

这个问题是驱动程序错误或应用程序冲突。我的笔记本电脑是戴尔inspiron 4030，就是它出现了这个问题。
