Communication is a difficult task for many people with autism. This can lead to frustration and isolation, and make it more difficult for people with autism to engage with friends, family, and their communities. Whether they are nonverbal, use only restricted words/phrases, or tend to repeat the same words, many people with autism can improve their communication with an augmentative and alternative communication (AAC) system.
AAC devices can help people with autism to communicate a much wider range of words, phrases, thoughts and feelings than they might be able to with speech or gestures alone. The use of AAC devices has shown to be a beneficial technique for people with autism (Nunes, 2008).
