Understanding Speech Development in Children With Autism

Autism Spectrum Disorder (also known as ASD) refers to a range of conditions that are characterized by challenges relating to social skills, repetitive behaviors, as well as speech and nonverbal communication. A study by the CDC in 2022 estimated that 1 in 31 participating 8-year-olds had ASD. 

Autism does not look the same for everybody. In fact, each person with ASD has a different set of strengths and challenges. Because of this, some people even receive this diagnosis later in childhood or even into adulthood. Signs of ASD may start appearing between the ages of 2 and 3; however, the average autism diagnosis in the United States happens around age 5.

Will My Child with Autism Learn to Speak?

Speech and language are complex skills that require various parts of the brain to work together. For children with autism, differences in brain development and sensory processing can impact how they process language, communicate, and interact socially. While not all children with autism experience speech delays, some do.

Some children with autism may begin speaking at the same time as their peers, but struggle with using language in socially appropriate ways. Others may be nonverbal, using other ways to communicate. Autism presents differently for everyone. Because of this, the question “Can a child with autism learn to talk?” has no single answer. Speech development for a child with ASD is highly individual and influenced by a variety of factors. 

Typical Speech Milestones vs Delays in Children With ASD

For typically developing children, speech and language milestones often follow a predictable timeline. It is important, however, to note that every child develops at their own pace. This is true for typically developing children as well as those with ASD.

Comparing the milestones may look like the following:

Babbling

• Typical: 6-9 months
• Children with ASD: May be delayed or absent 

First Words

• Typical: 12 months
• Children with ASD: May be delayed or absent

Two-Word Phrases

• Typical: 18-24 months
• Children with ASD: May be delayed or absent 

Social Use of Language

• Typical: 2-3 years
• Children with ASD: Often impaired. They may struggle with eye contact, using words in context, or turn-taking in conversations.

Speech may develop unevenly for children with autism. For example, a child may be able to label objects such as “car” and “dog” but not use these words to request or interact socially. Some children with ASD may echo words said by others (echolalia) without understanding the meaning. This is a common feature in autism speech development. Recognizing these signs early can lead to more effective interventions. 

Common Speech and Language Challenges for Children With ASD

Children on the autism spectrum may experience a range of communication difficulties. Some of these can include:

1. Delayed onset of speech
2. Limited vocabulary
3. Echolalia (repeating words or phrases without apparent meaning or conversational intent)
4. Struggles with conversational skills like greetings, eye contact, and tone of speech (pragmatics)
5. Nonverbal communication challenges, such as difficulty using or interpreting gestures, facial expressions, or body language.
6. Apraxia of Speech (a motor speech disorder that makes it difficult to plan and execute movements required for speech)

These challenges do not mean that a child will never talk; however, they do highlight the need for specialized support through speech therapy and family involvement. 

Factors Influencing Speech Development in Children with Autism

There are multiple factors that may determine when a child with autism will learn to talk, how much they will talk, and how effectively they can use language in daily life. 

Early Intervention

• The earlier speech therapy begins, the more opportunities the child will have to develop speech and communication skills. While there is no guarantee that a child with autism will develop and use their speech as much as their typical peers, seeking guidance from a speech therapist early will help them reach their full potential and help their families communicate more effectively with them.

Severity of Autism Symptoms

• There is a wide range of severity when it comes to symptoms of ASD. Children with milder symptoms may not have any delays in speech or only struggle with social communication. On the other hand, children with more significant cognitive or sensory impairments may remain nonverbal for longer, or permanently rely on augmentative and alternative communication (AAC) tools. 

Family Support & Environmental Factors

• Children who receive consistent language exposure at home, attend supportive schools, and interact with peers often show greater progress in language development. Families play a significant role by:
  • Modeling language during daily routines
  • Encouraging communication (verbal and nonverbal)
  • Reinforcing the use of words and phrases in the proper context

Use of Technology and AAC 

• For some nonverbal or minimally verbal children, AAC devices (like picture boards, communication apps, or speech-generating devices) can be life-changing. Research shows that using AAC encourages speech by reducing frustration and providing a consistent model. 

Speech Therapy for Autism

Speech therapy is proven to be beneficial for children with autism. A speech therapist will perform a comprehensive evaluation of the child’s ability to communicate. From there, they will design an appropriate treatment program. Improved communication skills are essential for helping children with ASD to reach their full potential, and speech therapy gives them the best opportunity. 

Key goals of speech therapy for autism may include:

• Expanding vocabulary and sentence length
• Teaching functional communication and conversation skills
• Improving understanding of spoken language
