我的python版本是3。7和Pyaudio版本是2。7程序在引擎初始化期间完全运行，但我不能使用Windows的sipas5，所以我使用了dummy

import pyttsx3
    engine = pyttsx3.init("dummy")
    voices = engine.getProperty('voices')
    engine.setProperty('voice', voices[0].id)

    def speak(text):
        print('Rex:' + text)
        engine.say(text)
        engine.runAndWait()

    print("On")
    speak("This program is running perfectly")
    print("End")

输出

On
Rex:This program is running perfectly
End

Process finished with exit code 0
