'''This file handles the text to speech aspect of the interactive story using the pyttsx module to 
produce the speech. Additionally, we use the win32api module for python, which encapsulates the Windows win32api, allowing
us to send a click to our avatar. Each click changes the current avatar animation being run, simulating a talking or idle state. '''
