pyttsx3 | Issues Initializing on MacOs

Question

I have a question regarding Python's "Text to Speech" module pyttsx3.

My Goal:

• Run pyttsx3 to speak a string of text.

Where I Stand:

• Installed pyttsx3
• Wrote the following lines in VS Code:

import pyttsx3
  engine = pyttsx3.init("nsss")
  engine.say("Hello World")
  engine.runAndWait()

Where I am Stuck:

• The code will not properly initialize.

See Error Message Below:

 Traceback (most recent call last):

You can't initialize pyttsx3 with nsss on Mac. I've had the same problem.

Run pip install py3-tts. You won't need a driver for pyttsx3.init() anymore.
