Key Word Sign

Key Word Sign is a type of augmentative and alternative communication (AAC). It’s a way of communicating that uses hand signs to represent the main or key words in a sentence at the same time as the words are spoken. Other common names for Key Word Sign include manual signing. Key Word Sign is suitable for anyone who has communication and language difficulties, including autistic people. Some research shows that Key Word Sign has positive outcomes for autistic children. For example, research shows that signing helps children make more vocal sounds and words than other forms of AAC. Also, signing doesn’t stop children from speaking when they can.

Research also suggests that Key Word Sign helps children most when it’s used as part of a program that includes other evidence-based therapies.

More high-quality studies are needed.
