AAC for adults, without being talked down to.
Most communication apps were built for children and are handed to adults unchanged. Cartoon symbols, reward sounds, a vocabulary with no words for work or money or refusing care, and settings labelled parental controls. Losing your speech should not also cost you being treated as an adult.
Why this keeps happening
It is not malice, it is market shape. AAC grew up around autistic children and the school and insurance funding that follows them, so every default got tuned for a seven-year-old. Adults were never the design target; they were an afterthought who got the same product with the same cartoon buttons.
The result is an app that undermines the person using it. An adult holding a screen covered in smiling cartoon faces is read by the room as childlike before they have said a word, which changes how people speak to them. The tool meant to restore their voice quietly costs them their standing.
The question that actually decides it
Not the diagnosis. Does this person read and spell?
If they read
Give them a keyboard with real word prediction and stored phrases. Typing beats tapping through symbol pages by a wide margin for anyone literate, and every page of navigation is delay added to a sentence they already know they want to say. This is usually right for ALS and for many people after a stroke.
If they do not
Give them a symbol board with adult words and adult imagery, plus their own photographs. Reading can also be uneven, especially with aphasia, so the honest answer is often both: a keyboard on the good days and a board on the hard ones, in one app, without picking a side at setup.
What to look for
An adult look you would carry in public
No mascots, no reward chimes, no primary-colour cartoons. This is not vanity. How a device looks changes how strangers, clinicians and family speak to the person holding it.
Adult vocabulary out of the box
Words for pain, money, work, sex, boredom, and for saying no to care. Most starter boards are built around snack time and cannot say leave me alone.
A keyboard that is a first-class mode
Not a corner button hidden behind the symbol grid. For a literate adult, text is the main route and symbols are the fallback, which is the reverse of how most apps are laid out.
It speaks with no signal
Communication cannot depend on a connection. If speech itself needs the internet, the app fails in the lift, the ward, and the car.
A voice that is not humiliating
Voice quality is dignity. If Apple Personal Voice is an option, record it early, especially with a progressive condition: it needs to be done while speech is still there.
Positions that never move
Buttons that shift between grid sizes or updates destroy the motor memory that makes a board fast. Fixed layout is the single most defended feature among people who rely on these apps.
If you are the person in the room
The device is half of it. The other half is you. Speak to the person, not to whoever is pushing the wheelchair. Wait longer than is comfortable, because a sentence built by tapping takes many times longer than one that is spoken, and filling the gap takes the conversation away. Do not finish their sentences, even when you are sure you are right. And assume they understand everything you say, including what you say about them, because they very probably do.
Questions people ask
What is the best AAC app for adults?
There is no single answer, because the deciding factor is whether the person reads. An adult who reads and spells is usually far faster with a keyboard and word prediction than with a symbol grid, and forcing them through symbol pages adds delay to every sentence. An adult who does not read reliably, or who has lost words after a stroke, needs a symbol board with adult vocabulary and adult imagery. Match the system to the person, not to their diagnosis.
Why do AAC apps feel like they are made for children?
Because most of them were. The market grew around autistic children and school funding, so the defaults follow: cartoon symbols, bright primary colours, reward sounds, and settings framed as parental controls. Those defaults get handed unchanged to a fifty-year-old after a stroke. The vocabulary is often wrong too, missing the words adults actually need for work, intimacy, money, and refusing care.
Can someone with aphasia use an AAC app?
Often yes, though aphasia is not one condition. Some people lose the ability to find words but keep comprehension entirely, and do well with stored phrases, photographs, and a partner who waits. Others read well enough to type. Aphasia also fluctuates, so a system that only works on a good day is not a system. Note that many apps sold for aphasia are therapy and practice tools rather than communication tools; those are a different thing from an app that speaks for you.
What do people with ALS need from AAC?
Speed first, then a path forward as the disease progresses. People with ALS typically retain full language and comprehension, so navigating symbol pages is pure friction. Text with strong word prediction is usually the right starting point, and recording a personal voice early is worth doing before speech deteriorates. Later stages may need switch access, scanning, or eye gaze.
Is it too late to start AAC as an adult?
No. Adults acquire AAC successfully in their sixties, seventies, and eighties. The obstacle is almost never age or capacity: it is being given a system built for a child, no time to learn it, and people around them who talk over the silence.
Something to use today
The communication board for adults and the hospital board are written with adult words and are free to print. If you are weighing up apps, several are genuinely free. SayHarbor is an AAC app designed adult-first, coming to iPhone and iPad. Speech is never behind a paywall.
