Speech suddenly shuts off during times of sensory overload for me. Non-verbal shutdowns can last anywhere from 5 minutes... to all day. This means I give up and go home without getting my errands completed, as I cannot communicate.
Soon I am thankfully getting a tablet and will buy a speech app. Does anyone else use one? Which AAC app do you use? Were you trained with it, or learned it yourself through tutorials?
Some examples of AAC apps are ProloQuo2Go, TalkTablet, Autismate, Tobii Dynavox Compass, and Touch Chat.
Anyway, I'd love to hear your experiences with AAC apps!
