Having problem using 'pyttsx3' on Ubuntu 20.04

I am on Ubuntu 20.04. Tried the following code on Pycharm CE. Just to speak out "Hello World".

import pyttsx3
pyttsx3.speak("Hello World!")

Getting the following output showing tons of errors. Please help!

 Traceback (most recent call last):

    eng = _activeEngines[driverName]

    o = self.data[key]()
