Abstract: This systematic review investigated the effects of augmented input on communication outcomes in people with developmental disabilities and people with childhood apraxia of speech who use aided augmentative and alternative communication (AAC). When working with individuals with little or no functional speech, clinicians often recommend that communication partners use the client’s AAC device when speaking to the client. This is broadly known as “augmented input” and is thought to enhance the client’s learning of language form and content. Nineteen studies met the inclusion criteria. Each included study was reviewed in terms of participant characteristics, terminology used, symbol format, augmented input characteristics, outcomes measured, effectiveness, and study quality. Results indicate that augmented input can improve single-word vocabulary skills and expression of multi-symbol utterances; however, comprehension beyond the single word level has not been explored. Additionally, it is difficult to form conclusions about the effect of augmented input on specific diagnostic populations. Directions for future research are discussed.
