我在运行一个简单的 pyttsx3 示例中遇到错误

Question

在 windows 和 rasbian 中分别使用 pyttsx3 和 python 3.8 和 2.7 有困难

当我尝试运行一个简单的基本 pyttsx3 代码时出现错误，请建议替换此 package.I 我正在尝试开发个人助理和我需要 pyttsx3 模块才能工作。在所有关于 pyttsx3 的教程中，它工作正常，没有任何错误，但是对于 python 3.8，它给出了错误。我尝试在 windows 和 raspbian 中使用这个包，两种情况下的错误都是一样的。

这是我正在尝试执行的一段代码，我已经安装了所有必要的模块 pywin32、pyttsx3、pyaudio、speechrecognition 一切。

import pyttsx3 
**engine = pyttsx3.init() 
engine.say('Hello sir, how may I help you, sir.')   
engine.runAndWait()** 

*it is giving error as:*
