VC调用TTS，封装为DLL

#include "tts05.h" ISpVoice* pVoice; HRESULT hr=-1; int speak1(int x1){ ::CoInitialize(NULL); if(!(hr==S_OK)) hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **)&pVoice); pVoice->SetVolume(100);//设置音量 pVoice->Speak(L"how are you?",SPF_ASYNC,NULL); ::CoUninitialize(); return 8; }
