What best defines augmentative and alternative communication (AAC)?

• A. A therapy technique for speech clarity
• B. A system to help or replace a person's natural communication
• C. A device to improve hearing
• D. A language development framework

Answer: (B)

AAC focuses on providing tools and strategies that help someone express themselves when their natural speech is limited, either by augmenting existing speech or replacing it entirely. It includes unaided options like gestures or sign language and aided options like communication books or speech-generating devices. It’s not primarily a therapy technique for speech clarity, not a device to improve hearing, and not a language development framework; it’s about enabling effective communication and participation in daily life.
