engine.setProperty('volume', 1.0)  # setting up volume level  between 0 and 1

"""VOICE"""
voices = engine.getProperty('voices')  # getting details of current voice
# engine.setProperty('voice', voices[0].id)  #changing index, changes voices. o for male
engine.setProperty('voice', voices[1].id)  # changing index, changes voices. 1 for female

engine.say('My current speaking rate is ' + str(rate))
engine.runAndWait()
engine.stop()
