Help with espeak in python

[menator01]

Using a basic function, this works for me

import pyttsx3

def speak(text):
    engine = pyttsx3.init()
    engine.say(text)
    engine.runAndWait()


speak('Hi there, what is your name?')

The wishme function

def wishme():
    engine
    hour = datetime.now().hour
    if hour < 24:
        engine.say('Good evening.')
    elif hour < 18:
        engine.say('Good afternoon.')
    else:
        engine.say('Good morning.')
    engine.say('How can I be of service?')
    engine.runAndWait()
