I made this module initially for myself but decided to release it for all the other Moto X users out there. It's really more for fun than useless. It basically makes your Moto X greet you with a custom audio message when you trigger Moto Voice.
NOTE: Audio greetings will not be enabled until the second time you trigger Moto Voice (This is a bug).
It should work on both 2013 and 2014 but I have only tested it on 2014.
