I discovered the VOCALYX through friends. Edward's difficulties are mostly to make himself understood: sometimes his father doesn't understand him well and often outsiders don't understand him at all. It took me a few hours to create his «world», his pictures, the pictos he understands and wants to use. Vocalyx allowed Edward to tell us what he was doing on the phone during the week. We live a little more with him in the week after all, and it's a lot for us and him.
