Unaided communication refers to communication methods that rely solely on the individual’s body without external tools or devices. This includes natural modalities such as gestures, body language, facial expressions, vocalizations, and sign language. In the context of Augmentative and Alternative Communication (AAC), unaided systems are distinguished from aided systems (which use external aids like picture boards or electronic devices) – for example, a person might communicate by nodding for “yes/no,” pointing, or using a formal sign language, all of which require no physical equipment.
Clinically, SLPs consider unaided strategies as part of a communication plan, particularly for individuals who may not always have access to their devices or for whom motor or sensory limitations make device use challenging.
