Is there a way to change pitch of local engine text-to-speech voice in python

问题

I am using text-to-speech in my python project but not getting any way to increase or decrease the pitch level of the local machine voice in python. Here is my basic code:

import pyttsx3
import datetime
import speech_recognition as sr
import random


print("Intializing Toretto")

engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
engine.setProperty('voice',voices[1].id)
engine.setProperty('rate', 210)

def speak(audio):
    engine.say(audio)
    engine.runAndWait()

回答1:

you should add a getProperty for the rate like this:

engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
rate = engine.getProperty('rate')
engine.setProperty('voice',voices[1].id)
engine.setProperty('rate', 210)
