Duke speech pathologists use augmentative and alternative communication (AAC) to help adults and children who have difficulty producing speech or whose speech is very difficult to understand. We support people with a wide range of communication problems including tracheostomy and ventilator dependence, traumatic brain injury, cerebral palsy, amyotrophic lateral sclerosis (ALS), and autism. Whether your need is temporary or long-term, we work closely with you to identify the best intervention to positively impact your quality of life.
