PyQt에서 pyttsx 사용

Question

pyqt에서 내 chatbot 용 Gui를 만들고 있지만이 영역의 코드에는 약간의 문제가 있습니다.

def __init__(self): 
    super(Window, self).__init__() 
    self.setGeometry(50, 50, 500, 300) 
    self.setWindowTitle("Chatbot 0.3") 


def offline_speak(chat_speech): 
    engine = pyttsx.init() 
    engine.say(chat_speech) 
    engine.runAndWait() 

몇 가지 다음 데프 offline_speak (자기)와 같은을 변경 초기화 위에 그것을에서 언급같은 self.offline_speak()을하지만 난 엔진 코드에 대해 아무 생각이 없습니다.

아무에게도 제안 할 수 있습니까?

Answer 1

offline_speak()을 클래스의 메서드로 만들 필요는 없지만이 작업은 매우 시간이 많이 걸릴 수 있으므로 Qt에서 생성 된 mainloop을 차단할 수 있으므로 표시 할 때 두 번째 스레드에서 실행하는 것이 좋습니다. QRunnable 및
