在 PyQt 中使用 pyttsx

Question

我正在用 pyqt 为我的聊天机器人制作 Gui，但我在这部分代码中遇到了一些问题。

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()

很少有事情会像 def offline_speak(self) 那样改变然后在上面提到它 init 比如 self.offline_speak() 但我不知道引擎代码。

谁能给我一些建议？

Answer 1

没有必要让offline_speak()成为class的一个方法，但是这个任务可能非常耗时，所以它会阻塞Qt生成的主循环，所以建议执行正如我在 QRunnable 和 QThreadPool

的帮助下展示的那样，它在第二个线程中

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)
text = """
