PyQtでpyttsxを使用

Question

pyqtで私のchatbot用のGuiを作っていますが、このコード領域に少し問題があります。

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() 

がいくつかようデフoffline_speak（自己）を変更します、その後のinitようself.offline_speak（）の上にそれを言及するが、私はエンジンのコードについては考えています。

誰も私に何かを提案できますか？

Answer 1

offline_speak()をクラスのメソッドにする必要はありませんが、この作業は非常に時間がかかるため、Qtによって生成されたメインループをブロックする可能性がありますので、2番目のスレッドで実行することをおすすめしますQRunnableとQThreadPool

import pyttsx 

from PyQt4.QtGui import * 
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)
