|

Rate differences
|
Can be a secondary strategy (i.e. person who stutters may speak quickly to avoid stuttering), but is not central to stuttering itself
|
Yes; mandatory for a diagnosis of cluttering (note that rate has to be rapid OR irregular, but does not have to be both)
|
Dysfluences | Mostly stuttering-like disfluencies (SLDs), such as repetitions, prolongations, blocks
|
Mostly non- stuttering- like disfluencies (NSLDs), such as interjections / filler words, phrases repetitions, revisions
|
Examples of dysfluencies:
|
Repetitions of sounds of syllables: y-y-you, wa-wa-watermelon Prolongations: sssso; thiiiis Blocks: sound gets stuck and person has difficulty moving forward to nextsound: p—eople |
Interjections/ filler words: um, uh Phrase repetitions: I love, I love NSA Revisions: I would like ice cream, no, please make that a shake |
Articulation difficulties (i.e. difficulties pronouncing sounds in words) |
Not in pure stuttering (i.e. stuttering without any additional communication disorders) | May sound “Mushy” and “Slurred”, typically can be corrected by such strategies as slowing down one’s speech rate |
Prosody (i.e. the rhythm and melody of one’s speech) | Typically normal | May be impacted; especially by change in pausing related to irregular rate. |
How it sounds | Repetitions, prolongations, blocks | Rushes of speech; lots of restarts |
Affective and cognitive components
|
Can be
|
Negative reactions and communication avoidance have been identified by consumers |
Pragmatics (i.e. social aspects of language) | Typically okay | A secondary consequence to decreased communication effectiveness.
