An AAC app may enter someone’s life at one point, but their communication needs will continue to change. The words that matter to a young child will likely differ from what a teenager or adult needs to say. As time passes, they may form new friendships, explore new interests, visit new places, begin school or work, and have more to express about their preferences, dislikes, thoughts, feelings, and goals.
A strong AAC app should develop alongside the person using it while keeping important words easy to locate. Growth is not just about adding more vocabulary. It is about making sure a person can keep using what already works while gaining new ways to communicate, greater independence, and more control over how they express themselves. A system that grows with the person should support these changes through vocabulary, access, personalization, voice, everyday use, and long-term flexibility.
Communication is about more than asking
Many people start using AAC to express basic needs like “I want juice,” “Help me,” “Bathroom,” or “More.” These words are important. They help people get what they need.
However, communication goes far beyond making requests. People use language to have conversations, complain, make jokes, ask questions, tell stories, share thoughts, discuss events, say “no,” change their minds, and join in conversations simply to be included.
Beyond basic words like “I,” “want,” “go,” “not,” “like,” and “why,” they need words specific to their own experiences. This might include names of loved ones and friends, favorite foods, interests, school subjects, jobs, places they go, music, games, pop culture, and words and phrases they use regularly.
What someone cares about shifts as they grow. A small child might mainly discuss toys, snacks, family, and everyday activities. As they get older, they often want to talk about friends, school, relationships, jobs, travel, music, future plans, and current events around them.
People also express themselves in different ways. A person might communicate using symbols, pre-made phrases, spelling, typing, word prediction, hand movements, sign language, facial expressions, or speaking, sometimes using several methods in one day. As reading and writing skills improve, they may want more ability to type and write their own messages instead of using ones already saved in the app.
New words should not make old words harder to find
When people use an AAC system on a regular basis, they often remember where their most-used words are located. That is why changing a layout too often can be annoying. If words that are used frequently keep moving every time new vocabulary gets added, the person may need to relearn parts of a system they already know well.
Language Acquisition Through Motor Planning, or LAMP, is one AAC method that puts strong focus on consistent motor patterns for finding words. In general, keeping frequently used words in the same places can make it easier for many AAC users to communicate.
An AAC system should be able to grow without having to rearrange everything all the time. New words, pages, and features can be added slowly while keeping the parts that work well already in place.
There is no single “right” way for communication to grow. Someone may use one word in one situation, use a saved phrase in another, and type out a longer message when they have the time and energy for it. The system should be able to support all of those ways of communicating.
How people use AAC systems can change too
Vocabulary is not the only thing that might change. The way someone uses their AAC system can also be different. At different times, a person may want bigger buttons, more space between them, touch help, a keyguard or switch access. They may also need different settings based on where they are or how they feel.
Things like being tired, vision problems, hearing issues, focus, body position, bright light, noise, or a crowded space can all change how someone accesses their device. A system that works well at home may need to work in a new way at school, outside, while traveling, or after a long day.
A good AAC app should allow for these changes. Someone should not have to give up their familiar words, pages, and personal settings just because they need a different way to reach them.
It should feel like their system
An AAC system should feel like it belongs to the person using it. A system set up for a young child might not feel right as they get older. As someone grows, they may want different symbols, colors, photos, topics, phrases, and ways to organize their words. They may also want a voice that matches their age, identity, language, dialect, or personality better.
Personalization goes beyond how things look. It can include the names people use, words from home, favorite sayings, cultural references, languages, pronunciations, photos, places, and things that are important to them.
Voice is important too. The voice an AAC user hears and shares with others can affect how they feel when talking. Being able to pick a voice, change how words sound, adjust how fast someone speaks, use a preferred language or dialect, or make other voice changes can help someone have more say in how they come across. AAC should help a person communicate clearly, but it should also help them sound like themselves.
As communication needs change, one AAC system may not always be the best fit for every situation. A system that works especially well with symbols, for example, may not offer the same experience for someone who later wants to use a keyboard-based system. They may choose to move to another system or use two systems for different situations. In those cases, having access to familiar or consistent voices across systems can make that transition much smoother. Whether the voice comes from the system itself or from voices such as Ivona or Acapela, being able to carry that sense of familiarity with them can matter.
Flexibility across devices can matter too. A person may use a tablet in one setting and a phone in another, or move between iOS and Android devices as their needs, preferences, or circumstances change. An AAC system that can adapt across devices and platforms can make it easier for a person to keep the communication experience that works for them as they grow.
AAC needs to work in everyday life
AAC is not just for therapy or planned talks. People use it during breakfast, in class, on buses, at cafes, at doctor visits, with friends, at family events, in stores, and at work. The words someone needs may change from place to place, but they should not have to learn a completely new system each time they go somewhere different. Their AAC should work across all parts of daily life while still feeling normal and easy to use.
It needs to keep working
For someone who uses AAC, an app is not just another tool. It might be their voice. That is why it must be simple to use, work reliably, and be there when needed. Common words should be fast to find, the layout should be clear, and tools like word prediction can help messages come together faster.
Key words and speech should work without the internet. People need to talk anywhere, not just when they have Wi-Fi or mobile data. It also matters that the system keeps working well when devices or apps get updated. Price, extra features, device requirements, and help from support can all change whether someone can keep using the same AAC system.
And then there is everything a person builds into their system over time. An AAC system can hold personal words, pages, photos, phrases, voices, access settings, and memories. That is why backup and restore choices are so important. If a device is lost, broken, swapped out, or cleared, a backup can stop someone from having to build their talk system all over again.
Growth means having more control
An AAC system should not simply keep adding more words as a person grows. It should keep making more of life possible.
The real question is not just, “How much more can this person say?” It is “How much more can this person do with their communication?”
Can they start a conversation without waiting for someone else to ask a question? Can they tell someone when they disagree? Can they correct a misunderstanding? Can they talk about something they care about, make a plan, change their mind, or decide what happens next?
That is where growth becomes meaningful.
A child who once needed AAC mainly to ask for something may eventually use it to make a joke with a friend, tell a story about their day, argue for what they want, talk about their interests, make plans for the future, or simply say something because they have something to share.
That is the kind of growth an AAC system should make room for.
Because the goal is not to give someone more words just for the sake of having more words. The goal is to give them more possibilities, more ways to participate, more ways to connect, and more opportunities to have a say in their own life.
A communication system that truly grows with a person does not decide who they will become. It gives them the space, tools, and freedom to show us.
