A comparison of stutterers and nonstutterers in a task of controlled voice onset. 1982

A R Mallard, and D M Hicks, and D E Riggs

The purpose of this study was to determine if stutters and nonstutters differed in their ability to initiate phonation repeatedly with a gentle voice onset. Ten stutterers and ten nonstutterers were asked to phonate the vowel /a/ with an average rise time slower than 52.3 dB/sec while starting the voice at or below 63 dB SPL. Voice productions were monitored by a voice monitor, which is used in the administration of the Precision Fluency Shaping Program. Measurements of number of attempts and time to reach criterion, percentage of correct productions, and intensity levels of each production were made. There were no significant differences between the two groups for any of the variables examined. Results were compared with other studies demonstrating phonatory differences between stutterers and nonstutterers.

D013342	Stuttering	A disturbance in the normal fluency and time patterning of speech that is inappropriate for the individual's age. This disturbance is characterized by frequent repetitions or prolongations of sounds or syllables. Various other types of speech dysfluencies may also be involved including interjections, broken words, audible or silent blocking, circumlocutions, words produced with an excess of physical tension, and monosyllabic whole word repetitions. Stuttering may occur as a developmental condition in childhood or as an acquired disorder which may be associated with BRAIN INFARCTIONS and other BRAIN DISEASES.
