Document Summary
Fluency disorders (cont"d: avoiding a word by describing it, indirect way of saying it, fire truck - the red thing, you know, with ladders and sirens. Silent pauses: an abnormally long silent duration between words and sentences (no struggling, as there is with a block) I"ve known (pause) him for years: an abnormally long silent duration within words. Frequency: typical speakers and people who stutter have disfluencies, listeners report 5% or more as abnormal, on average, people who stutter are disfluent on 10% of their words. Duration: a disfluency of one second or more is considered indicative of stuttering. We don"t know exactly why people stutter: not psychiatric, personality, or nervous disorder. People generally don"t stutter when they: sing, whisper, speak in chorus. May be because you hear voice less: or do not hear their own voice. There is no universally accepted explanation for these phenomena.
