Fluency is the smoothness in which sounds, syllables, words and phrases are joined together during oral language. A fluency disorder is any interruption in the flow of oral language.


The following are the major types of dysfluencies and their examples:



Part-Word Repetitions - Repetition of a part of a word, sound or syllable.

Ex: S-S-S Sunday

Ex: Su-Su-Su- Sunday


Whole-Word Repetitions - Repetition of an entire word more than once.

Ex: I-I-I love the Cubs

Ex: They-they-they will win


Phrase Repetitions - Repetition of more than one word. Ex: I am-I am- I am a Cubs fan



Sound Prolongations -Where the sound is held out for a duration of time.

Ex: WWWanda


Silent Prolongations - A silent period where the lips are closed and pursed ready to produce the sound but nothing comes out.


Interjections - Can be sound or syllable interjections, word and phrase interjections.


Broken words - Silent intervals within the words. Ex: Be---fore you talk


Incomplete Sentences - Described as incomplete sentences. Ex: Last night I…Last night…we went to see the Cubs


Revisions - Changes in wording that do not change the overall meaning of the sentence or phrase.

Ex: Let’s have a drink--coffee
