Augmentative and Alternative Communication (AAC) includes all tools and strategies used to support or replace spoken language for individuals with complex communication needs. AAC may be low-tech (e.g., picture boards) or high-tech (e.g., speech-generating devices), and supports both children and adults with conditions like cerebral palsy, autism, and aphasia. SLPs assess individual needs and match clients with appropriate systems. Therapy focuses on building communication autonomy, teaching both user and partner skills. AAC empowers users to express wants, needs, and social messages.
