Verwenden Sie pyttsx in PyQt

Question

Ich mache Gui für meine Chatbot in Pyqt, aber ich habe ein bisschen Problem in diesem Bereich des Codes.

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() 

paar Dinge wie def ändern offline_speak (Selbst-) dann über init wie self.offline_speak erwähnen in(), aber ich habe keine Ahnung von Maschinencode.

Kann mir jemand etwas vorschlagen?

Answer 1

Es ist nicht notwendig, offline_speak() eine Methode der Klasse zu machen, aber diese Aufgabe kann sehr zeitaufwendig sein, damit sie die von Qt erzeugte Hauptschleife blockieren kann. Daher ist es ratsam, sie in einem zweiten Thread auszuführen die Hilfe von QRunnable und QThreadPool

import pyttsx

from PyQt4.QtCore import * 


class SpeechRunnable(QRunnable): 
    def __init__(self): 
     QRunnable.__init__(self) 
    def run(self): 
     self.engine = pyttsx.init() 
     self.engine.say(self.chat_speech) 
     self.engine.runAndWait() 

    def say(self, text): 
     self.chat_speech = text 
     QThreadPool.globalInstance().start(self) 

    def stop(self): 
     self.engine.stop() 


class Window(QWidget): 
    def __init__(self): 
     super(Window, self).__init__() 
     self.runnable = None 
     self.setWindowTitle("Chatbot 0.3") 
     lay = QVBoxLayout(self) 
     self.le = QLineEdit(text, self) 
     self.btnStart = QPushButton("start", self) 
     self.btnStop = QPushButton("stop", self) 
     self.btnStart.clicked.connect(self.onClickedStart) 
     lay.addWidget(self.le) 
     lay.addWidget(self.btnStart) 
     lay.addWidget(self.btnStop) 


    def onClickedStart(self): 
     self.runnable = SpeechRunnable() 
     self.runnable.say(self.le.text()) 
     self.btnStop.clicked.connect(self.runnable.stop) 

    def closeEvent(self, event): 
     if self.runnable is not None: 
      self.runnable.stop() 
      QThread.msleep(100) #delay 
     super(Window, self).closeEvent(event)
