How to create the clear voice using pyttsx3 on Ubuntu?

[GoldenDragon0710]

I just used pyttsx3 for generating voice from the text with below code in Ubuntu 22.04.
The voice was cracked and it was not clear when playing audio file. But I got the clean audio file when running the same code in Windows 10.
How to create clear voice using pyttsx3 in Ubuntu 22.04?

import pyttsx3

engine = pyttsx3.init("espeak")
voices = engine.getProperty('voices')
engine.setProperty('rate', 160)
engine.setProperty("voice", voices[11].id)

# Save audio file
def speak(text):
    engine.say(text)
    engine.save_to_file(text, "output.wav")
    engine.runAndWait()

speak("Hello world and this is a test.")
