Data on disfluencies in the speech of non-stuttering adults are relevant to several aspects of the assessment and treatment of adults who stutter. Currently, very few sources provide relevant data.

Comparison of acoustic correlates of phonatory control in the fluent utterances of 10 preschool-aged boys who were stutterers and in nonstuttering control subjects found significant differences between the two groups for shimmer measures. (Author/DB)

This paper reviews evidence that characteristics of the perceptually fluent speech of stutterers change as a function of a number of variables and that, because these variables are difficult to fully control, comparison of the characteristics of the perceptually fluent speech of stutterers and nonstutterers as a method of studying stuttering…

A study of overt audible speech behavior in eight male and one female Swedish adults examined the relationship between disfluency and speaking modality, disfluency type in mild versus severe stutterers, and disfluency and psycholinguistic variables. Three conditions of experimental manipulation were used: reading aloud, reading the longer lines of…
