Came across this site a while back, thought it would be helpful to the people who dont know about it.

Basically its a text to speech website so you can make them say pretty much anything. Some messages sound really funny in the other languages but for the most part Crystal is on point. My boys went crazy when she said "Mr.Bonner you've got a new text message"
Have Fun.
P.S for those who dont know just save the wav, rename it and drop it in the windows folder. It should pop up under notifications.
