title: Is there a way to change pitch of local engine text-to-speech voice in python
body: <p>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:</p>
  
  <pre><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()
  </code></pre>
