Stammering & Autism

Read about the link between stammering and autism.

Disfluencies in speech is common for people on the autistic spectrum. Autism affects the way people experience the world around them. It also affects the way they communicate. 

Every person with autism is different. Some people may talk very little, while others may talk a lot and be very fluent. Some people may be very aware of their disfluencies. They may develop negative thoughts and feelings about their speech. Others may have little or no awareness that their speech patterns are disrupted.

The range of disfluencies can be quite broad, and includes features such as:

  • Stammering, or stuttering as it's called in other parts of the world. This includes prolonging/stretching sounds, repeating sounds or words, or having silent blocks. Particularly at the beginning of words, but it can occur anywhere in a sentence. See our page What Is Stammering? for more information.
  • The normal disfluencies present in everyone's speech, but at a higher rate than is typical. This includes 'um's and 'er's, hesitations, rephrasing and pauses.
  • Less common disfluencies. This can include repeating sounds at the end of words, or repeating words at the end of a phrase or sentence. Or it could be inserting extra sounds in the middle of words.

How to help

Here are some tips for helping someone with autism who is stammering:

  • Give them time to plan what they want to say.
  • Say exactly what you mean. People with autism spectrum conditions can take things literally. Don't use slang, sarcasm or idioms such as "She's as cool as a cucumber" or "It went down to the wire". People will find these hard to understand.
  • Eye contact can be very uncomfortable for some people with autism spectrum conditions. Don't be offended if the person doesn't make eye contact with you during a conversation.
