VC6.0 C++ 如何调用微软windows系统SDK 语音API

下载3个语音API安装包 http://www.microsoft.com/en-us/download/details.aspx?id=10121

需要安装微软语音API安装包:SpeechSDK51LangPack、SpeechSDK51以及 msttss22L、

为了在VC中使用这SDK,必需在工程中添加SDK的include和lib目录,为免每个工程都添加目录,最好的办法是在VC的
    
    Option->Directoris立加上SDK的include和lib目录。也可以直接将sapi.h sapi.lib 分别放到VC6的 头文件合库文件中

    一个最简单的例子

 #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, NULL);

pVoice->Release();

pVoice = NULL;}

::CoUninitialize(); //释放

return TRUE;

}

详细解释:

void voice_succeed()
{
ISpVoice * pVoice; //pVoice指针

::CoInitialize(NULL);  //初始化COM库

//获取核心的应用程序接口ISpVoice接口

CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **)&pVoice);//创建识别引擎

pVoice->Speak(L,NULL);

//发音 speak 参数详解:1.用来输入文本字符串 2.标志speak的方式 3.获取当前文本输入等候播放队列位置

pVoice->Release();//释放资源

pVoice->Release();//释放资源

::CoUninitialize(); //释放资源

}

用CoInitialize(), CoCreateInstance()获取IspVoice接口就够了, 程序结束前一定要用CoUninitialize()释放资源。
    
 获取IspVoice接口,然后用ISpVoice::Speak()把文本输出为语音,程序的核心就是IspVoice接口。

把文本语音输出为WAV文件

   #include <sapi.h>

    #include <sphelper.h>

    #pragma comment(lib,"ole32.lib")

    #pragma comment(lib,"sapi.lib")

    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 ) )

    {

    CComPtr<ISpStream> cpWavStream;

    CComPtr<ISpStreamFormat> cpOldStream;

    CSpStreamFormat OriginalFmt;

    pVoice->GetOutputStream( &cpOldStream );

    OriginalFmt.AssignFormat(cpOldStream);

    hr = SPBindToFile( L"D:\\output.wav",SPFM_CREATE_ALWAYS,

    &cpWavStream,&OriginalFmt.FormatId(),

    OriginalFmt.WaveFormatExPtr() );

    if( SUCCEEDED( hr ) )

    {

    pVoice->SetOutput(cpWavStream,TRUE);

    WCHAR WTX[] = L"<VOICE REQUIRED=''NAME=Microsoft Mary''/>text to wave";

    pVoice->Speak(WTX, SPF_IS_XML, NULL);

    pVoice->Release();

    pVoice = NULL;

    }

    }

    ::CoUninitialize();

    return TRUE;

    }
