The challenge of using words is a core part of autism, but that doesn’t mean your child can’t communicate or learn to communicate more effectively. It just means they may need different tools, different paths, and a supportive team which often includes both ABA and speech therapy walking alongside them.
This article will walk you through speech delays, scripting and echolalia, AAC (augmentative and alternative communication), and nonverbal and “unreliable” speech to give you with the information you need to advocate resources for your child.
A Quick Overview of Autism and Communication
Autism spectrum disorder (ASD) is a developmental difference that often affects social communication and interaction, as well as how a child behaves and processes the world around them. Communication differences are very common in children on the spectrum.
Many autistic children have delays in speech and language, or difficulty understanding what others say.
FACT: Estimates suggest 25–30% of children with autism may be minimally speaking or non-speaking, relying more on nonverbal communication or AAC.
Other reports note that roughly 40% may not develop spoken language at all without intensive support, while many others show significant delays.
The important takeaway is that communication differences in autism are common and varied and there are evidence-based ways to support them.
Speech Delays: When Talking Comes Late (or Not at All)
Look at this checklist to see if your ASD child is experiencing communication challenges:
___ Not using words by age 2–3
___ Saying a few words but not combining them into phrases
___ Losing words, they had used before
___ Understanding less than you’d expect for their age
When speech is delayed, it’s easy to feel pressure to catch up to others, but for autistic kids, speech and understanding often develop at a different pace and in a different order.
A speech-language pathologist (SLP) will typically look at how your child understands language (following directions, recognizing names). How they express themselves (sounds, words, gestures, pointing, facial expressions) and how interested they are in sharing experiences (showing you toys, bringing you things, etc.).
From there, the SLP can build a plan that may include spoken language, gestures, and often AAC (more on that shortly).
Scripting and Echolalia: Why Repeating Means Something
Many autistic children communicate using echolalia or scripting. The definition is as follows:
Echolalia means repeating what someone else just said, or something they heard before
Scripting is using memorized lines from movies, shows, books, or previous conversations
For years, echolalia was seen as something to get rid of, but current research and professional organizations like ASHA now recognize that echolalia can be a functional, meaningful way to communicate, process language, and manage emotions.
Echolalia and scripting can help children participate in interactions when they don’t yet have flexible language. These strategies can also show you what they are thinking about or feeling (even if the words are borrowed), and provide a starting point for teaching more personalized, flexible phrases.
Good therapy doesn’t try to erase echolalia, instead it treats it as communication style. Therapy can help your child move from scripts toward more flexible, self-generated language.
Nonverbal and Unreliable Speech
Some autistic children don’t use spoken words at all or use only a few words. Many times, they can speak clearly at home but lose speech when anxious, overwhelmed, or in unfamiliar settings.
Autistic advocates and clinicians often describe this behavior as having unreliable speech, meaning that the ability to speak comes and goes depending on stress, sensory load, and environment. This doesn’t mean your child has nothing to say. It does mean that spoken words may not be the best or only way for them to communicate right now. That’s where augmentative and alternative communication (AAC) comes in.
What Is AAC or Augmentative and Alternative Communication?
AAC refers to any way of communicating that is not spoken words, including low-tech means like gesturing, pointing, and sign language. Your child may also communicate using picture cards or boards, and other communication books.
Some high-tech means of alternative communication are speech-generating devices and tablet apps where your child taps pictures or words and the device speaks for them. There are also some custom systems that can be programmed with your child’s favorite people, foods, places, and routines
Research shows that AAC can significantly improve communication for children with autism and other developmental disabilities, especially when started early and used consistently.
Keep in mind that AAC does not prevent speech. In fact, studies suggest AAC can support language development and participation in school. ACC is also not meant to encourage the idea of giving up on talking, instead, it’s a way to give your child a voice, right now, while speech skills grow at their own pace. Finally, AAC systems work best when therapists, teachers, and family members all use and reinforce the protocol.
Behavior Can Get Bigger When Communication Is Hard
When a child can’t say, “I’m tired,” “That’s too loud,” or “I want the blue cup,” their needs don’t disappear, they just come out in other ways. When communication is hard, children resort to screaming, hitting, throwing things, and running away.
Functional communication training (FCT), a widely used and evidence-based ABA approach, has a strong research base showing it can reduce challenging behavior by teaching more appropriate ways to communicate needs.
How ABA and Speech Therapy Can Help Your Child with Communication
ABA therapy is particularly strong at breaking skills into small steps and teaching them in real-life contexts using reinforcement. Speech therapy is strong in designing the language targets like which words to use, how to model them, and how to expand them.
Together ABA and speech therapists can choose a simple way for your child to make a request from a word, sign, picture, or button on an AAC app. They can also assist your child in practicing designated language skills during your child’s daily routines.
What Therapy Can Look Like for a 4–8-Year-Old
Here are a few real-life style examples of how ABA and speech therapy can help (details changed for privacy).
Example 1: The Non-Speaking 5-Year-Old
Before: Child screams and hits when snack time comes, then grabs food from siblings.
After: With a picture-based AAC system and FCT, they learn to hand you a “snack” card or tap “I want snack” on a tablet. Screaming drops because their request is understood and honored quickly.
Example 2: The 7-Year-Old Who Scripts
Before: When asked, “How was school?” they respond with a cartoon script: “Well folks, that’s all for today!” Parents feel like they “can’t have a real conversation.”
After: SLP and ABA team notice the script comes after enjoyable days. They model: “You’re saying, ‘School was fun!’ Let’s try, ‘School was fun today!’” Over time, the child begins to mix the script with new phrases: “School was fun. We did art.”
Example 3: The 6-Year-Old with Unreliable Speech
Before: Talks at home but goes silent at school, then pushes peers when they get too close.
After: Team introduces a simple AAC app and teaches the child to tap “Stop,” “Go away,” and “All done.” At school, the child begins using the device to get space instead of pushing. Speech is encouraged, but they now have a backup when words disappear.
What You Can Do as a Parent Right Now
You don’t need a perfect plan to start supporting communication today. These five practical steps can be adopted right away.
- Notice and Respond to All Forms of Communication
Try to respond when your child:
- Points
- Brings you an object
- Looks back and forth between you and something interesting
- Uses a script in a meaningful moment
- Keep Your Language Simple and Clear
- Use short, concrete sentences: “Put on shoes,” “Drink water,” “All done.”
- Pair words with gestures and pointing.
- Repeat key phrases often in the same context.
- Build in Easy Ways to Request – start with the basics:
- “More”
- “Help”
- “All done”
- “Stop”
- “Break”
Whether it’s a word, sign, or picture, make these requests easy and powerful and when your child uses them, respond quickly.
Ask About AAC Early: If your child has limited or unreliable speech, ask your pediatrician, SLP, or ABA provider about AAC evaluation and options. Early AAC is associated with better language and participation outcomes.
Look for Teams Who Collaborate: When exploring services, ask the following.
- “How do your ABA and speech therapy teams communicate with each other?”
- “Will we have shared goals around functional communication and behavior?”
- “How do you involve parents so we can carry these skills into daily life?
One More Thing: Your Child Is Communicating
Even if your child doesn’t use many spoken words yet, they are communicating through movement, sounds, looks, behavior, and scripts. Your job isn’t to make them communicate like everyone else; it’s to help them communicate in ways that let them be understood, keeps them safe, honors their autistic identity, and opens up their world at home, school, and beyond.
With the right combination of speech therapy, an ABA focus on functional communication, and tools like AAC, many children make meaningful progress in expressing themselves and reducing frustration-related behaviors. If you’d like to know more, contact us at 480-770-0850.
