Here is my code:

```
#include <sapi.h>

int main(int argc, char* argv[])
{
    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"Hello world", 0, NULL);
        pVoice->Release();
        pVoice = NULL;
    }

    ::CoUninitialize();
    return TRUE;
}

```

This is my very first SAPI 5.1 Run, and this is the sample hello world provided by MS.

I have added the SAPI "bin" location to the system variable "Path". 

Following is my QT project contect (.pro content)

Please note that SAPI include in the last include and SAPI lib is the last lib.

When I run this code, the followng error is generated.

```
C:\Users\yohan\Documents\QTPeojects\Tired\Speech.cpp:10: error: C2143: syntax error : missing ')' before ';'
C:\Users\yohan\Documents\QTPeojects\Tired\Speech.cpp:10: error: C2059: syntax error : ')'

```

I do not understand why.

Update
------

The above error is now gone after following the instructions from John. But, now the below errors are generated. Why is that?

```
Speech.obj:-1: error: LNK2019: unresolved external symbol __imp__CoUninitialize@0 referenced in function _main
