Choosing an AAC Device for Your Child

If your child has more to say than spoken words can carry, an AAC device or app can open a door, and choosing an AAC device that truly fits is one of the most important decisions you will make.

Augmentative and alternative communication (AAC) is any tool, strategy, or technology that helps a child communicate when speech alone is not enough. That might be a picture board, a dedicated speech-generating device, or an app on a tablet your child already loves. The good news: there is no single 'best' device, only the best fit for your child, and a clear process for finding it. This guide walks you through that process in plain language, with New Jersey-specific tips along the way.

Start Here: What AAC Is (and One Myth to Let Go Of)

AAC covers a wide range of options, from 'low-tech' tools like picture cards and communication boards to 'high-tech' speech-generating devices and tablet apps that speak aloud when your child taps a symbol or types. Many families begin with one and layer in others over time. If you are brand new to all of this, our overview of what AAC is and the communication options for autism is a friendly place to start.

One worry comes up in almost every first conversation: If my child uses a device, will they stop trying to talk? The research is reassuring and consistent. Studies have found that AAC does not hinder speech, and in many cases it actually supports speech development. In one widely cited review, the large majority of children showed gains in speech production after AAC intervention, and none showed declines. AAC gives your child a way to communicate now, which reduces frustration and often builds the very foundation that spoken words grow from.

Choosing an AAC Device Starts With an Evaluation

The single most important step in choosing an AAC device is a comprehensive AAC evaluation by a speech-language pathologist (SLP) who has experience with autism. This is not a quick checklist. A good evaluation looks at how your child currently communicates, their motor and sensory profile, their vision, their attention, their interests, and the real-life situations where they most need to be understood, at home, at school, and out in the community.

An SLP-led evaluation matters because the 'obvious' choice is not always the right one. A child who loves a tablet may still struggle with a particular app's layout, or may do far better with a sturdier dedicated device. The evaluation replaces guesswork with evidence. In New Jersey, AAC assessments are a covered service for children under 21 through NJ FamilyCare (Medicaid) under the EPSDT autism benefit, and many private insurers cover them too.

Ask who is evaluating. Look for an SLP familiar with AAC and autism specifically.
Bring your observations. Note when your child gets frustrated, what they already point to or reach for, and how they let you know 'yes' and 'no.'
Include the whole picture. Sensory needs and motor skills shape which devices will actually work day to day. Our guide to sensory processing and autism can help you describe these.

How Feature Matching Works When Choosing an AAC Device

The method professionals use is called feature matching: instead of starting with a product, you start with your child's needs and abilities, then match those to the features a device or app offers. The American Speech-Language-Hearing Association (ASHA) provides feature-matching charts that SLPs use to do this systematically.

Here are the features that matter most when you are choosing an AAC device or app:

Access method: Can your child touch a screen accurately, or do they need larger buttons, a keyguard, or even eye-gaze or switch access?
Vocabulary organization: Does the system grow with your child, from a few core words to full sentences, and is the layout consistent so symbols stay in the same place (motor planning)?
Symbols and voice: Photos, picture symbols, or text? Is there a child's voice option? Can the display be simplified for sensory comfort?
Durability and portability: Will it survive daily life, travel between home and school, and hold up to drops?
Programmability: How much customizing are you, the parent, willing and able to do? Some apps are highly flexible; dedicated devices may be more locked-down but simpler.
Cost and funding path: Dedicated medical devices are often covered by insurance or Medicaid; consumer tablet apps usually are not, though the tablet sometimes can be.

No device wins on every feature. Feature matching is about finding the strongest overall fit for your specific child.

Dedicated Device vs. Tablet App: Which Direction?

One of the first forks in the road is whether to pursue a dedicated speech-generating device or an AAC app that runs on a tablet. Both can be excellent. Here is how families and SLPs usually think it through.

A dedicated device is built only for communication. It tends to be more durable, has long battery life, locks out games and distractions, and, importantly, is more likely to be funded by insurance or NJ FamilyCare because it is classified as a medical device. The trade-off is cost if paid out of pocket and less flexibility.

A tablet-based app (the kind that turns an iPad or Android tablet into a 'talker') can be more affordable up front, familiar, and easy to update. The trade-offs: the device is also a tempting source of games and videos, it may be less rugged, and the app itself is often not covered by insurance. Some families use a guided-access or 'kiosk' mode to keep the tablet focused on communication.

There is no universally correct answer. A child who needs a distraction-free, durable tool may thrive with a dedicated device, while a child who is highly motivated by a tablet may take to an app immediately. This is exactly why the evaluation and a real trial matter so much, and it mirrors the kind of individualized decision-making we talk about in communicating with a nonverbal autistic child.

Try Before You Commit: The Power of a Device Trial

You would not buy a car without a test drive, and AAC is no different. A child's success with a particular device often cannot be predicted from the evaluation alone, which is why trials are a normal and recommended part of the process. During a trial, your child uses one or more systems in real situations for a stretch of time so you can see what actually clicks.

Ways to trial without spending money:

Loan programs. Many AAC manufacturers offer free device loans or lite versions of their apps so you can try before buying.
New Jersey AAC centers. Specialized assistive-technology and augmentative communication centers in NJ provide trials, evaluations, and help navigating funding.
Your SLP's library. Many SLPs keep a small collection of devices and apps to test with your child during sessions.

During a trial, watch for the signals that matter: Does your child reach for the device on their own? Can they find the words they want? Are they communicating more, not just answering prompts? Those are the signs of a good match.

Funding Your AAC Device in New Jersey

Cost should not be the reason a child goes without a voice, and in New Jersey there are real paths to coverage. For children under 21, NJ FamilyCare (Medicaid) covers medically necessary alternative communication assessments and devices under the EPSDT autism benefit, with an SLP's prescription tied to a communication need related to autism. Many private insurance plans also cover dedicated speech-generating devices when documented as medically necessary.

Get the documentation right. A detailed AAC evaluation and a letter of medical necessity from your SLP are the backbone of most approvals.
Lean on specialists. NJ augmentative communication centers help families navigate insurance and Medicaid paperwork, which can be the trickiest part.
Know your appeal rights. If a request is denied, you can appeal. The same persistence that works for therapy denials applies here, much like the steps in our guide to appealing an insurance denial.

If your child is already receiving services, your ABA and speech teams can coordinate on the documentation. For families just beginning, see what NJ FamilyCare covers for autism-related services.

The Device Is the Beginning, Not the Finish Line

Choosing the right device is a milestone, but a device on a shelf does not teach communication. What turns a tool into a voice is daily, motivating use, modeling by the adults around your child (you using the device yourself as you talk), and teaching that connects symbols to real wants and needs. This is where ABA and speech therapy work powerfully together.

In ABA, we often start by teaching your child to request the things they want (manding) using their AAC system, because requesting is naturally rewarding and builds momentum fast. Over time, the same system supports commenting, asking questions, and connecting with others. Our team works alongside your SLP so that the device is used consistently across in-home therapy sessions and everyday routines.

Frequently asked questions

Will using an AAC device stop my child from learning to talk?

No. Research consistently shows that AAC does not hinder speech and often supports it. By giving your child a reliable way to communicate, AAC reduces frustration and can build the foundation that spoken words grow from. Many children show gains in speech after starting AAC.

Do I need an evaluation before choosing an AAC device?

Yes, an evaluation by a speech-language pathologist experienced in autism and AAC is the recommended first step. It uses 'feature matching' to align your child's abilities and needs with the right device or app, rather than guessing. In NJ, AAC assessments are a covered service for children under 21 through NJ FamilyCare.

Is a dedicated speech device better than a tablet app?

Neither is universally better. Dedicated devices are durable, distraction-free, and more often covered by insurance as medical devices. Tablet apps can be more affordable and familiar but may invite distractions and are often not covered. The right choice depends on your child, which is why a trial matters.

Can I try an AAC device before buying it?

Yes, and you should. Many manufacturers offer free loaner devices or lite app versions, and New Jersey assistive-technology centers offer trials. A trial lets you see whether your child reaches for the device on their own and communicates more before any money is spent.

Will insurance or Medicaid in New Jersey pay for an AAC device?

Often, yes. NJ FamilyCare (Medicaid) covers medically necessary alternative communication assessments and devices for children under 21 under the EPSDT autism benefit, and many private plans cover dedicated speech-generating devices. A strong evaluation and a letter of medical necessity from your SLP are key, and denials can be appealed.
