C++语音识别接口快速入门（Microsoft Speech SDK） 
尤其注意其中的宽字符串转化

 

直接调用read（“  ”）就可以朗读了

#include
using namespace std;
#include //导入语音头文件
#include
#pragma comment(lib,"sapi.lib") //导入语音头文件库


void  MSSSpeak(LPCTSTR speakContent)// speakContent为LPCTSTR型的字符串,调用此函数即可将文字转为语音
{
ISpVoice *pVoice = NULL;


//初始化COM接口


if (FAILED(::CoInitialize(NULL)))
MessageBox(NULL, (LPCWSTR)L"COM接口初始化失败！", (LPCWSTR)L"提示", MB_ICONWARNING | MB_CANCELTRYCONTINUE | MB_DEFBUTTON2);


//获取SpVoice接口


HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void**)&pVoice);




if (SUCCEEDED(hr))
{
pVoice->SetVolume((USHORT)100); //设置音量，范围是 0 -100
pVoice->SetRate(0); //设置速度，范围是 -10 - 10
hr = pVoice->Speak(speakContent, 0, NULL);


pVoice->Release();


pVoice = NULL;
}


//释放com资源
::CoUninitialize();
}
//string转换车wstring  
std::wstring  StringToWString(const std::string& s)
{
std::wstring wszStr;


int nLength = MultiByteToWideChar(CP_ACP, 0, s.c_str(), -1, NULL, NULL);
wszStr.resize(nLength);
LPWSTR lpwszStr = new wchar_t[nLength];
MultiByteToWideChar(CP_ACP, 0, s.c_str(), -1, lpwszStr, nLength);
wszStr = lpwszStr;
delete[] lpwszStr;
return wszStr;
}
void read(string temp){

wstring a = StringToWString(temp);
LPCWSTR str = a.c_str();
/*不知道为什么Cstr不行*/
MSSSpeak(str);
cout << "朗读结束\n";
}


int  main(){


read("你好  世界");
return 0;
}
