关于SAPI的两段小代码(c++)

要运行这些代码需要进行配置编译器的.

SAPI配置基于vc++6.0

语音模式:

#include ＜sapi.h＞ #pragma comment(lib,"ole32.lib") //CoInitialize CoCreateInstance需要调用ole32.dll #pragma comment(lib,"sapi.lib") //sapi.lib在SDK的lib目录,必需正确配置 int main(int argc, char* argv[]) { ISpVoice * pVoice = NULL; //COM初始化： if (FAILED(::CoInitialize(NULL))) return FALSE; //获取ISpVoice接口： 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; } //千万不要忘记： ::CoUninitialize(); return TRUE; }

监听模式:

#include <windows.h>#include <sapi.h>#include <stdio.h>#include <string.h>#include <atlbase.h>#include "sphelper.h"inline HRESULT BlockForResult(ISpRecoContext * pRecoCtxt, ISpRecoResult ** ppResult){    HRESULT hr = S_OK;    CSpEvent event;    while (SUCCEEDED(hr) &&           SUCCEEDED(hr = event.GetFrom(pRecoCtxt)) &&           hr == S_FALSE)    {        hr = pRecoCtxt->WaitForNotifyEvent(INFINITE);    }    *ppResult = event.RecoResult();    if (*ppResult)    {        (*ppResult)->AddRef();    }    return hr;}const WCHAR * StopWord(){    const WCHAR * pchStop;        LANGID LangId = ::SpGetUserDefaultUILanguage();    switch (LangId)    {        case MAKELANGID(LANG_JAPANESE, SUBLANG_DEFAULT):            pchStop = L"}42N86\0b70e50fc0ea0e70fc/05708504608a087046";;            break;        default:            pchStop = L"Stop";            break;    }    return pchStop;}            int main(int argc, char* argv[]){    HRESULT hr = E_FAIL;    bool fUseTTS = true;            // turn TTS play back on or off    bool fReplay = true;            // turn Audio replay on or off    // Process optional arguments    if (argc > 1)    {        int i;        for (i = 1; i < argc; i++)        {            if (_stricmp(argv[i], "-noTTS") == 0)            {                fUseTTS = false;                continue;            }            if (_stricmp(argv[i], "-noReplay") == 0)            {                fReplay = false;                continue;            }                   printf ("Usage: %s [-noTTS] [-noReplay]  ", argv[0]);            return hr;        }    }    if (SUCCEEDED(hr = ::CoInitialize(NULL)))    {        {            CComPtr<ISpRecoContext> cpRecoCtxt;            CComPtr<ISpRecoGrammar> cpGrammar;            CComPtr<ISpVoice> cpVoice;            hr = cpRecoCtxt.CoCreateInstance(CLSID_SpSharedRecoContext);            if(SUCCEEDED(hr))            {                hr = cpRecoCtxt->GetVoice(&cpVoice);            }                       if (cpRecoCtxt && cpVoice &&                SUCCEEDED(hr = cpRecoCtxt->SetNotifyWin32Event()) &&                SUCCEEDED(hr = cpRecoCtxt->SetInterest(SPFEI(SPEI_RECOGNITION), SPFEI(SPEI_RECOGNITION))) &&                 SUCCEEDED(hr = cpRecoCtxt->SetAudioOptions(SPAO_RETAIN_AUDIO, NULL, NULL)) &&                SUCCEEDED(hr = cpRecoCtxt->CreateGrammar(0, &cpGrammar)) &&                SUCCEEDED(hr = cpGrammar->LoadDictation(NULL, SPLO_STATIC)) &&                SUCCEEDED(hr = cpGrammar->SetDictationState(SPRS_ACTIVE)))            {                USES_CONVERSION;                                            const WCHAR * const pchStop = StopWord();                CComPtr<ISpRecoResult> cpResult;                printf( "I will repeat everything you say.
