Not every child with autism speaks. Some use a few words, some use none, and some communicate in other ways. If your child is nonverbal, you may feel worried and unsure where to turn. This guide explains what the term means, why it happens, and the ways children learn to communicate.
The short answer: a child who does not speak can still communicate, learn, and make progress. The goal of support is to give your child a reliable way to share what they want and need. That way can be words, pictures, signs, or a device.
What does “nonverbal” mean?
“Nonverbal” describes a person who does not use spoken words to communicate. Clinicians also use these terms:
- Minimally verbal: uses fewer than about 30 words or word-like sounds.
- Nonspeaking: a term many autistic people and families prefer, because it describes speech and says nothing about understanding.
Estimates suggest that up to about 30 percent of autistic children are minimally verbal or nonverbal. Nonverbal does not mean silent. Many of these children make sounds, gesture, lead you to what they want, or use pictures.
Does nonverbal mean a child does not understand?
No. Speech and understanding are separate skills. A child can understand a great deal and still find it hard to speak. Some nonspeaking children understand language well, and some have an intellectual disability as well. A professional assessment can describe your child’s understanding. Speak to your child with respect and assume they take in what you say.
Why do some autistic children not speak?
There is no single cause. Researchers point to several factors:
- Differences in how the brain connects language, movement, and social understanding.
- Difficulty planning and coordinating the mouth movements needed for speech. This is called apraxia of speech, and it can occur alongside autism.
- Difficulty with the social side of communication, such as noticing that sharing words connects you to others.
- Hearing problems or other medical issues. A hearing test is a standard first step.
Nothing a parent did causes a child to be nonverbal.
Ways children communicate without speech
Communication tools are called augmentative and alternative communication (AAC). Using AAC does not stop speech from developing. Many families find that it reduces frustration and gives children a reason to communicate.
- Gestures and signs: pointing, waving, or learning simple signs.
- Picture exchange (PECS): a child hands over a picture to request an item or activity.
- Picture boards and books: a child points to symbols to build messages.
- Speech-generating devices: a tablet or device that speaks when the child touches a symbol or word.
A speech-language pathologist can help you pick the right tool and teach your child to use it.
How ABA therapy supports communication
A Board Certified Behavior Analyst (BCBA) assesses your child’s current communication and builds goals around it. ABA programs often focus on:
- Functional communication: teaching your child to ask for things they want, such as a snack or a break, in a way that works for them.
- Imitation and attention: building the early skills that support learning sounds, signs, and words.
- Replacing frustration behaviors: when a child has a clear way to say “stop” or “I want that,” challenging behaviors often decrease.
- Using AAC across the day: therapists and parents use the same tool in sessions, at meals, and during play.
Our post on ABA and communication skills goes deeper on how this works. Parents play a key role, and parent training shows you how to use these strategies at home.
Can a nonverbal child learn to speak?
Some do, and some do not. Progress varies. Many children who start with AAC or signs also begin to use spoken words. Children can build new communication skills at any age, and a child does not have a window that closes. Your team sets goals one step at a time and measures progress with data.
How you can help at home
- Respond to every attempt. A look, a reach, or a sound counts. Respond right away so your child learns that communication works.
- Give choices. Hold up two items and let your child pick by looking, pointing, or reaching.
- Model the words. Say the word as you hand over the item. Keep it short and clear.
- Use the same tool everywhere. Keep the picture board or device within reach at home, at school, and out in the community.
- Celebrate small steps. A new gesture or a new picture is real progress.
Frequently asked questions
Is nonverbal autism the same as Level 3 autism?
Not always. A child at any support level may be nonverbal, though it is more common at higher support levels. Read our guide to the levels of autism for more.
Will an AAC device keep my child from speaking?
Research does not show that AAC prevents speech. Many children use more speech once they have another way to communicate.
What should I do first?
Ask your pediatrician for a hearing test and a referral to a speech-language pathologist. If your child has an autism diagnosis, an ABA assessment can set communication goals.
