What’s the Difference Between Autism and Speech Delay?

June 6, 2025

Autism and speech delay can look similar at first—but they’re not the same.


Speech delay simply means a child is developing language skills more slowly than expected. These children may still use gestures, make eye contact, and show interest in social interaction—they just talk later.


Autism, on the other hand, often includes speech delay plus other signs. Children with autism might avoid eye contact, have trouble with back-and-forth conversation, or show limited interest in people. Their communication challenges are part of a broader difference in how they understand and engage with the world.

Understanding the difference is key to getting the right support. A proper evaluation helps determine whether your child needs speech therapy, ABA therapy, or a combination of both.
