Same with my nephew. He also has autism and the first thing the speech therapist did when he was 3 was teach him simple sign language. It became such a great catalyst for communication. He's nowhere near his his age (now 6) developmentally but within ~6 weeks he went from completely non-verbal to actually vocalizing the simple words he learned the sign language for.
