1.将sapi.dll导入到C++Builder:
Component->Import Component->Import a Type Library->Add添加Sapi.dll语音识别引擎库文件。
2.Install完后会自动生成.cpp | .h文件。

3.将.cpp|.h文件添加如工程，引用，可以进行编程了。

直接播放声音：

void TTSSpeaker(UnicodeString AText) {SpVoice * pVoice;if (SUCCEEDED(::CoInitialize(NULL))) {if (::CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpeechVoice,(void **)&pVoice) == S_OK)try {pVoice->SetRate(0); // 语速 0 -> 20 pVoice->SetVolume(100); // 音量 0 -> 100pVoice->Speak(AText.c_str(), 0, NULL); }__finally {pVoice->Release();}::CoUninitialize();}}

生成wav文件

void TTSSaveAsWav(UnicodeString AText,UnicodeString filename) {SpVoice * pVoice;if (SUCCEEDED(::CoInitialize(NULL))) {if (::CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpeechVoice,(void **)&pVoice) == S_OK)try {SpeechVoiceSpeakFlags spFlags =SpeechVoiceSpeakFlags::SVSFlagsAsync;SpeechStreamFileMode spFileMode =SpeechStreamFileMode::SSFMCreateForWrite;SpFileStream *spFileStream;if (::CoCreateInstance(CLSID_SpFileStream, NULL, CLSCTX_ALL,IID_ISpeechFileStream, (void **)&spFileStream) == S_OK) {spFileStream->Open(filename.c_str(), spFileMode, false);pVoice->_set_AudioOutputStream(spFileStream);pVoice->Speak(AText.c_str(), spFlags);pVoice->WaitUntilDone(1000);spFileStream->Close();}}__finally {pVoice->Release();}::CoUninitialize();}}
