AAC myths and facts: 10 common myths, and what the research says

The biggest AAC myths are that it stops people from learning to talk, that a person has to be old enough or “ready” first, and that AAC means an expensive device. Research reviews haven’t found that AAC holds speech back, the professional guidance says there are no prerequisites, and AAC includes gestures, signs and paper boards as well as speech apps. Here are ten myths, each answered with a source you can check.

These myths come up again and again, from families, teachers and sometimes professionals. Each answer links to where it comes from. For decisions about one person, talk to a speech-language pathologist who knows them.

One-page AAC myths and facts handout: a box saying what AAC is, with pictures for gestures, picture boards, writing and apps that speak; ten numbered myths, such as AAC will stop my child from learning to talk, each with a one-line fact; and where the facts come from, with a line to write in who to ask.
The handout. The line at the bottom right is for your name or your team’s.

Hand it out at a first AAC appointment, before a team meeting or at a staff training, or give it to grandparents and babysitters who worry that a board will get in the way of talking. Point to the one myth the person is worried about rather than all ten, and talk it through. The handout is free to print, copy and share; please don’t sell it.

Myth 1: AAC will stop my child from learning to talk

Fact: research hasn’t found this. A 2006 review looked at studies of AAC and speech in children and adults with developmental disabilities. In the 27 cases from the best-designed studies, none showed less speech after AAC was introduced, 89% showed gains, and 11% stayed the same. Most of the gains were modest.1

A 2010 trial with 68 toddlers who said fewer than 10 words found that children in the two groups taught with augmented communication used both augmented and spoken words, and ended with larger vocabularies than children in the spoken-only group. The authors concluded that augmented communication does not hinder, and actually aids, speech in young children with developmental delays.2 For autistic children, our guide to AAC and autism sums up three reviews.

The honest summary: AAC doesn’t hold speech back and may help a little, but it isn’t a promise that someone will talk. Its first job is to let the person communicate now.

Myth 2: AAC is a last resort, for when speech therapy has failed

Fact: AAC should be considered as early as possible, whatever the cause of the communication difficulty, and preferred practice combines it with the person’s speech, gestures and other ways of communicating.3 “Augmentative” means adding to speech; people who use AAC can use both speech and AAC to talk to others.4

For example, the professional guidance for childhood apraxia of speech lists AAC as part of treatment, used to support speech while it is still developing.5 See AAC and childhood apraxia of speech.

Myth 3: My child is too young for AAC

Fact: children younger than three can start.4 Some families and professionals think young children aren’t ready until school age, but the professional guidance says early AAC use can help develop speech and language, and can increase vocabulary for children with developmental delays aged three and younger.3

The US Department of Education lists the idea that infants and toddlers don’t benefit from assistive technology as a myth, and gives AAC, such as pictures of activities or objects or a handheld tablet, as an example of what can help.6 See AAC for toddlers.

Myth 4: A person has to be “ready”, or learn certain skills first

Fact: there are no prerequisites for AAC. The professional guidance says this directly, and supports a zero-exclusion policy: everyone whose communication doesn’t meet their needs is a candidate, and the time and effort AAC takes is not a reason to leave anyone out.3

It also answers a specific version of this myth: the idea that skills such as understanding cause and effect, or showing an intention to communicate, have to come first. Impaired cognition does not rule out communication.3 No thinking skills, test scores or other milestones are needed before AAC can help.4

Myth 5: AAC means an expensive speech device

Fact: AAC includes no-tech and low-tech tools. Gestures, signs, facial expressions, communication boards and books, pictures, photos and writing are all AAC, as well as apps and devices that speak.3 The US Department of Education makes the same point about assistive technology in general: it isn’t always electronic or high-tech, and many tools cost little or nothing.6

You can start today with paper. Read how to get started with low-tech AAC, print a core word board, or start with one core word a week.

Myth 6: AAC is only for people who can’t talk at all

Fact: many people use AAC alongside speech. Some people use AAC all the time; others use it now and then, to help people understand their speech; others need it only for a short time, for example after surgery.4 AAC is called augmentative when it adds to existing speech, and alternative when it is used in place of speech.3

A child who talks at home but can’t be understood at school, or an adult whose speech gets harder when tired, may both benefit.

Myth 7: AAC is only for children

Fact: AAC is for people of all ages. Adults may need it after a stroke or a brain injury, with progressive conditions such as ALS, after surgery such as removal of the voice box, or for a short time in intensive care.3 See AAC for adults and how to talk with someone who has aphasia.

Myth 8: You need good hand control to use AAC

Fact: people use AAC with their arms, feet, head or eyes.4 A board doesn’t have to be touched: choices can be made with eye gaze, a head pointer or scanning with a switch, or with a partner who reads out the choices while the person signals yes.3 See AAC and cerebral palsy for the ways to choose.

Myth 9: AAC should be limited, like screen time, or kept for therapy

Fact: people who use AAC should always have access to it. Concerns about screen time for young children don’t apply to screens used as part of an AAC system.3 The US Department of Education adds that a child who needs a communication device will need it with them at all times of the day, not only in class.6

A device used only at home, and not at school or work, may not work as well as it could.3 Keep it within reach at meals, in the car, in the bath (a paper copy) and at bedtime. AAC at home has ideas for every room.

Myth 10: We tried AAC once and it didn’t work, so it isn’t for us

Fact: you can try again. A public information page powered by the American Speech-Language-Hearing Association puts it plainly: even if you tried once before, you can try again, and it’s never too early or too late.4

Success with a particular system often can’t be judged at the first assessment, and trying devices is a normal part of AAC therapy.3 Before you give up, look at the known reasons AAC gets dropped: words that don’t matter to the person, too little training for the people around them, a setup that doesn’t match how they move or see, and too little family involvement in choosing it.3 Each of these can be changed.
