We all know Roger Ebert back when he use to provide reviews of movies. He unfortunately had cancer and lost his ability to use his voice and up until recently was using a program on the computer with a generic voice to "speak".
This is something i found on gizmodo. A company was able to integrate Roger Eberts actual voice into the program by sampling his voice from all the shows that he's done.
I am definitely very hopeful for the future and the amazing things some people are capable of.
