Depending on the severity of CAS I have used AAC as a way to decrease frustration and anxiety a child has if they are able to produce speech sounds, words, phrases and sentences but often have errors and are not always easily understood. I have also used a variety of AAC devices for children that have severe CAS to ease communication challenges and open the doors for them to communicate more readily with family, friends, at school, etc while also continuing to target motor planning for speech sounds to try and acquire some verbal speech.
