01 / Multimodal by design
Use every reliable route. Do not make speech the tollbooth.
ASHA describes AAC as inherently multimodal: a person may combine speech or vocalizations with gestures, signs, facial expression, objects, pictures, photographs, writing, spelling, communication boards, text-to-speech and speech-generating devices. The mix can change by place, communication partner, motor access, fatigue, sensory load and message.
AaSpeech + vocalization
Words, approximations, sounds, intonation, laughter and other intentional vocal signals.
✋Gesture + sign
Pointing, reaching, conventional gestures, manual signs, body orientation and established movements.
▦Symbols + pictures
Photographs, visual scenes, communication books, symbol grids and meaningful objects.
⌨Writing + spelling
Handwriting, typing, texting, alphabet boards and text-to-speech when independently accessed.
◉Eye gaze + scanning
Direct eye-gaze selection, switches, auditory or visual scanning, and partner-assisted scanning.
▣Speech-generating tech
Dedicated devices, tablets or phones with robust symbol- or text-based language systems.
A useful distinction: message vs. route
“I need a break” is the message. Speech, pressing a symbol, looking to a “break” card, signing, pointing to the door or selecting “yes” during partner-assisted scanning are possible routes. When one route becomes hard, the message still deserves another route.
Behavior can carry information. It is not a mind-reading system.
A change in movement, pacing, vocalization or facial expression may tell a familiar partner that something is different. Respond to the person and the situation, but do not assign a precise message without a way to confirm it. “You seem uncomfortable. Is something wrong?” plus an accessible way to answer protects agency better than deciding what the behavior “means.”
Visual example: a tiny backup board
This is deliberately small: it is the sort of emergency board that might live in a pool bag or glove compartment. It is not a substitute for a person’s full vocabulary.

ASHA’s 2026 AAC Awareness Month materials specifically highlight public communication boards as useful low-tech access in places such as libraries and parks. A public board is an additional route—not a reason to leave someone’s personal AAC behind.
