[急切求助]如何使用SAPI实现批量文本转换成wav语音(现在只实现转换一条)

Question

#include <sapi.h>
#include <sphelper.h>//可以多次朗读文本
void CSapitestDlg::OnSpeak() 
{
    UpdateData();
    ISpVoice * pVoice = NULL;    if (FAILED(CoInitialize(NULL)))
    {
        AfxMessageBox("Error to intiliaze COM");
        return;
    }    

    HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **)&pVoice);
    if( SUCCEEDED( hr ) )
    {
        hr = pVoice->Speak(m_Text.AllocSysString(), 0, NULL);
        pVoice->Release();
        pVoice = NULL;
    }    CoUninitialize();
}//文本转换成语音，只能转换一条
//同时转换多条记录有问题 !!!!!!
void CSapitestDlg::OnRecord() 
{

Answer 1

把生成的"ttsTest.wav"文件删除掉,
再次进行转换则不成功,
只能转换一条记录.

Answer 2

//下面的代码可以实现朗读文本，并转换成wav文件；
//用到的语言包是：Microsoft Speech SDK 5.1；
//使用sapi如何设置音频的频率等参数？

#include <sphelper.h>  //文本转换成wav文件//朗读文本
