AAC stands for augmentative and alternative communication: all the ways a person gets a message across beyond speech alone—gestures, signs, picture boards, speech-generating devices. It is not a last resort, it is not only for children who will never speak, and the research does not support the fear that it holds speech back. AAC gives a child something to communicate with while everything else keeps developing.
What AAC actually is
The phrase sounds technical; the idea is not. Augmentative means added to speech, alternative means used in place of it, and together they cover an enormous range:
Things a body already does
Gestures, pointing, facial expression, leading someone by the hand. Every child arrives with some of this, and it is genuinely communication.
Sign
From a handful of everyday signs to a full signed language.
Low-tech tools
Picture symbols, communication boards, choice cards, a laminated page of core words. No batteries, and often the most portable option in the house.
Speech-generating devices
A tablet or dedicated device running a vocabulary app that speaks aloud when a child selects words. Dr. Taylor is formally trained across a range of these systems, including TouchChat, LAMP Words for Life, Unity, and Tobii Dynavox.
Most children who use AAC use several of these at once—and so does everyone else: you gesture while you talk, point at a menu, text instead of calling.
Who AAC can help
AAC is often introduced for children who are nonverbal or minimally speaking. It also helps children whose speech is hard for others to understand, whose speech comes and goes with regulation or fatigue, who understand far more than they can say, or who are building spoken language and need a reliable way to be heard meanwhile.
At Little Luminaries, the question is never “does this child deserve a device?” It is “does this child have a dependable way to say what they mean, in every room?” If not, AAC is worth exploring.
Five myths worth retiring
“Using AAC will stop my child from talking”
The worry: if the device does the talking, my child has no reason to try—and we trade away the speech they might have had.
Research and clinical practice broadly agree that this does not happen. Reviews of the evidence have not found that introducing AAC suppresses speech; the more common finding is that speech stays the same or increases. ASHA’s clinical resource on augmentative and alternative communication summarizes that evidence base. The intuition is understandable; it simply is not how communication develops. Giving a child a working way to be understood makes communicating more rewarding, not less.
“AAC is a last resort, for after speech therapy hasn’t worked”
The worry: we should exhaust every avenue toward speech first, and turn to AAC only when options run out.
Waiting has a cost that is easy to overlook. Every month a child cannot reliably ask, refuse, comment, or object is a month of communication lost—and of the frustration that comes with it. AAC is not the consolation prize at the end of the process; it can run alongside speech work from the beginning, and starting forecloses nothing.
“My child has to be a certain age, or show they’re ready first”
The worry: there are prerequisites—a certain age, proven understanding, the ability to match pictures, demonstrated “readiness.”
The field moved away from prerequisite thinking a long time ago. ASHA’s National Joint Committee holds that no one should be excluded from communication services because of skills they have not yet demonstrated. Nobody asks a baby to prove readiness before speaking to them, and the same logic applies here. What changes with age and skill is which system fits, not whether a child qualifies.
“A device will replace real human connection”
The worry: more screen, less eye contact, less closeness. A child disappearing into a tablet.
AAC is not a screen a child is left alone with; it is a tool used between people. Families often describe the opposite of what they feared: more back-and-forth, more jokes, more arguing about bedtime—more of the small ordinary exchanges connection is made of. The device is not the relationship; it is one more way into it.
“Choosing AAC means giving up on speech”
The worry: agreeing to AAC is a quiet admission that we have stopped believing our child will talk.
It is not an either/or, and never was. Plenty of children use AAC and speech together, in the same sentence, choosing whichever works in the moment. Some use AAC for a season and less of it later; some use it for life. All of those are good outcomes, because the goal was never speech for its own sake—it was a child who can say what they mean. At Little Luminaries, we are not trying to make a child seem less like themselves; we are trying to give them more ways to be heard.
The goal was never speech for its own sake—it was a child who can say what they mean.
What starting actually looks like
It starts with an evaluation built to match a system to the child, not the other way round. An AAC evaluation looks at how your child already communicates, what their body and vision do easily, what vocabulary they would actually want, and how the system has to work at home, at school, and in the car. Device trials are part of it where they make sense.
Then everyone learns to model. This is the part families are least warned about, and it matters most: AAC is a language, and languages are learned from fluent people using them nearby. Nobody hands a toddler a vocabulary list and waits. So we use the system ourselves, out loud, in ordinary moments—not as a drill, and without requiring a response. That is how it becomes theirs.
If a system is already in your house and stalled on the counter, that is one of the most common places families get stuck—and almost never because the child could not do it. Usually what is missing is coaching for the people around your child.
