The types of stuttering most commonly seen are below. These show how the stuttering is produced. And show what the person who stutterers does when they stutter.
Stuttering Disfluencies are classified as:
- Single syllable whole word repetitions – like “I-I-I-I-I want a cup.”
- Part word and sound repetitions – like “give me a cu-cu-cu-cup.”
- Sound repetitions – like “give me a c-c-c-c-cup.”
- The shorter the repetitions element, the more severe i.e. sound repetitions.
- Prolongations – like “My cuuuuuuuuup is small.”
- Blocks – stoppage of any sound or breath flow when trying to produce words.
Normal disfluencies are present in persons who do not stutter and are not counted as Stuttering Disfluencies. And these include:
- Phrase repetitions or revisions – like “I went to, I went to the park” or ” I went to, I mean I ran to the park”
- Multisyllable whole word repetitions like – “My breakfast, breakfast was very good”
- Interjections – like “um, ah, uh” are not counted as stuttering disfluencies.
New names for types of stuttering in the DSM-5
In the latest DSM-5 (Diagnostic and Statistical Manual) stuttering has a new name. Stuttering is no longer an official diagnosis. Instead, the name of the disorder has been changed to Childhood-Onset Fluency Disorder. Also known as Developmental Stuttering, this new diagnosis describes a speech disorder that has it’s beginning in childhood. And it usually starts during the pre-school years whatever the cause. And if the disorder appears during adolescence or adulthood, the classification is Adult-Onset Fluency Disorder which is much rarer.
