Fluency disorder means that children experience trouble speaking in a fluid or flowing way. A child may say the whole word or parts of the word more than once or pause between words. This is known as stuttering.

A child may speak fast and jam words together often. This is called cluttering.

These changes in speech sounds are called disfluencies. Many people have a few disfluencies in their speech, which is normal. But if you have a fluency disorder, you will have many disfluencies when you talk, making being understood a daily struggle.
