How to fix compiler errors in SAPI 5.1 Header File

Question

I got a lot of errors from SAPI 5.1 provided header files and cannot figure out how to fix those problems.

Following is a simple Text to Speech program from Microsoft’s How to Video Presentation. The presenter said, if you have installed the most updated packages, you will have no problem compile this program. But he is using Video Studio 2005; apparently the “most updated” refers a few years ago when the presentation was given.

I think these errors are caused version miss match. I am using Windows XP SP3. I have Visual Studio 2008 SP1, Visual Studio 2008 SDK 1.1, Windows SDK v6.0A(come with VS2008), Windows SDK v7.0 and SAPI 5.1. Can someone help me figure out these problems?

TTSdemo.cpp

#include <windows.h>
#include <atlbase.h>
#include <sapi.h>
#include <sphelper.h>
#include <string>
#include <iostream>

int wmain(int argc, wchar_t **argv)
{
    int i;
    ULONG n;
    HRESULT hr;
    std::wstring args;
    CComPtr<ISpObjecToken> token;
    CComPtr<ISpVoice> tts;
    CoInitialize(0);

    for (i = 1, args = L""; i < argc; i++ )
    {
        args.append( argv[i] );
        args.append( L" " );
    }

    tts.CoCreateInstance(CLSID_SpVoice);
    hr = SpGetDefaultTokenFromCategoryId(SPCAT_VOICES, &token, FALSE);
    hr = tts->SetVoice(token);

    if (args.length() == 0 )
        std::wcout << L"Enter @<text file name> or <text to speak>" << STD::endl;
    else if ( args(0) == L'@' )
        tts->Speak(args.c_str() + 1, SPF_IS_FILENAME | SPF_ASYNC, &n);
    else
        tts->Speak(args.c_str(), SPF_IS_XML | SPF_ASYNC, &n);

    tts->WaitUntilDone(-1);

    tts.Release();
    token.Release();

    CoUninitialize();

    return 0;
}

Answer 1

Please use "\Program Files\Microsoft SDKs\Windows\v6.0A" or 7.0 or 7.0A whatever latest available on your computer.

The SAPI DLL's and libs + header files are there, compatible for VS2008

Enjoy.
