python - 在我的程序中使用 pyttsx3 时出现错误

Question

我使用 pyttsx3 进行文本到语音的转换，但它显示错误。我使用了包括 pypiwin32 在内的所有必需模块，但即使我已经卸载了 2.7 的旧版 python，目前我使用的是 python 3.9 版本。

这是代码

import speech_recognition as sr
import pyttsx3


listener = sr.Recognizer()
engine = pyttsx3.init()
engine.say('hello I am aura')
engine.say('how may i help you')
engine.runAndWait()
try:
 with sr.Microphone() as source:
     print("listening...")
     voice = listener.listen(source)
     command = listener.recognize_google(voice)
     command = command.lower()
     if 'aura' in command:

         print(command)

except:
 pass

这是错误

During handling of the above exception, another exception occurred:
