What Is AAC? Augmentative Communication Options for Autism

If your child has a lot to say but spoken words do not come easily, you are not alone, and there are proven tools that can help. AAC for autism, short for augmentative and alternative communication, gives your child a reliable way to be understood right now, while still supporting speech for the future.

AAC is not a last resort and it is not a sign of giving up on talking. It is a bridge to connection. In this guide, we will walk through what AAC actually is, the main options available, the research that puts a common worry to rest, and the practical steps New Jersey families can take to get started, including how AAC fits alongside ABA therapy.

What AAC for autism really means

AAC stands for augmentative and alternative communication. The word augmentative means it adds to whatever communication a child already has, like gestures or some words. The word alternative means it can serve as the main way a child communicates when speech is not yet reliable. In plain terms, AAC is any method of communicating that is not spoken words, used to help a person express wants, needs, thoughts, and feelings.

Every one of us already uses a form of AAC. When you point at a menu item, wave hello, or text a friend, you are communicating without speaking. For autistic children, especially the roughly 25 to 35 percent who remain minimally verbal even after early services, a structured AAC system can be the difference between frustration and being understood.

The American Speech-Language-Hearing Association (ASHA) groups AAC into two broad families, which we will look at next: unaided systems that use only the body, and aided systems that use an external tool.

The main types of AAC for autism

There is no single right tool. Good AAC for autism usually blends several modes so your child can communicate with different people, in different places, for different reasons. Here are the main categories.

• Unaided AAC (no equipment needed): facial expressions, gestures, pointing, and manual signs such as American Sign Language signs. These are always available because they use only the body.
• Low-tech aided AAC: communication boards, picture cards, and printed symbol books. The picture exchange method, where a child hands you a picture to make a request, is a well-known low-tech approach.
• High-tech aided AAC: tablets and dedicated speech-generating devices that speak aloud when a child taps a symbol or types. Many families start with an AAC app on an iPad.

Experts recommend a multimodal approach, meaning your child is not locked into one method. A child might sign "more" at the dinner table, tap a tablet to choose a show, and hand over a picture card at school, all in the same day. If you are weighing devices and apps, our guide on how to choose the right AAC device or app walks through the decision step by step, and our overview of how PECS builds communication covers the picture exchange method in depth.

Will AAC stop my child from talking?

This is the question we hear most often, and it is completely understandable. The good news is that the research is reassuring and consistent: AAC does not hinder speech, and it often helps.

A widely cited research summary found that across studies, 87 percent of participants showed improvement in their vocal output, and no study reported a decrease in spoken language when a speech-generating device was part of the intervention. In other words, giving your child a voice through AAC does not take away their motivation to talk. For many children, it does the opposite, because communicating successfully is rewarding and pairs spoken words with meaning.

It helps to think of AAC as scaffolding, not a cast. It supports communication while spoken language has room to grow, and it never has to be removed for speech to develop. If you are wondering about the bigger picture, our honest look at what the research says about whether your child will talk offers more perspective for families navigating this question.

How AAC works alongside ABA therapy

AAC and ABA therapy fit together naturally. Speech-language pathologists typically lead the selection and programming of an AAC system, while ABA teams help your child use it functionally throughout the day, across real situations and with real motivation.

One of the most powerful overlaps is teaching requesting, also called manding. When a child learns to tap "I want bubbles" on a device and bubbles immediately appear, the system becomes meaningful fast. ABA also uses AAC within functional communication training, where a clear, easy way to ask for a break or for help replaces behaviors like hitting or screaming that may have been the child's only way to communicate a need.

Our team weaves AAC use into everyday routines, from snack time to play, so the device or board is not just a therapy-room tool but a true voice your child carries with them. You can read more about our approach on our services page.

How New Jersey families can get started

Getting the right AAC system usually starts with an evaluation by a speech-language pathologist who has AAC experience. The evaluation looks at your child's strengths, motor skills, vision, and the settings where they need to communicate, then matches those to a system. Many devices and apps are covered by insurance or NJ FamilyCare when documented as medically necessary, so keep that evaluation report.

• For children under age 3: reach out to NJ Early Intervention, which can begin communication supports before preschool.
• For school-age children: AAC can be written into an IEP as assistive technology, and the school district may be required to provide a device and training.
• Try before you commit: New Jersey families can borrow AAC tools through assistive technology lending programs, and some local libraries also offer devices to try.

Because we serve families across all 21 NJ counties with in-home support, our team can help your child practice their AAC system in the place it matters most, your home. See where we work on our locations page, browse our parent resources library, or get started with a conversation about your child's communication goals. You can also reach us directly at 732-664-0038.

Supporting your child's AAC at home

An AAC system works best when it is part of family life, not locked in a backpack. A few simple habits make a big difference.

• Model it yourself. Tap or point to symbols as you talk, the same way you would narrate words to a baby. This is called aided language modeling, and it shows your child how the system works without pressure.
• Keep it available all the time. A device or board only helps if it is within reach during meals, play, car rides, and bedtime.
• Honor every message. If your child uses AAC to protest or say "no," respond as you would to spoken words. Communication should always work, even when the message is one you did not hope for.
• Be patient with pace. Give your child time to find and select symbols without jumping in to finish for them.

If your child is currently minimally verbal, our practical guide to communicating with a nonverbal autistic child offers more everyday strategies you can use right away.
