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. In the existing literature on normally fluent speakers, there is no consistency in sample length or topic or in which types of disfluency are counted.…

The present study investigated the dysfluencies in the speech of nine French speaking individuals with fragile X syndrome. Type, number, and loci of dysfluencies were analysed. The study confirms that dysfluencies are a common feature of the speech of individuals with fragile X syndrome but also indicates that the dysfluency pattern displayed is…

Purpose: Previous research has demonstrated the fluency-improving effect of reducing the occurrence of short-duration, phonated intervals (PIs; approximately 30-150 ms) in individuals who stutter, prompting the hypothesis that PIs in these individuals' speech are not distributed normally, particularly in the short PI ranges. It has also been…

Disfluency characteristics of 36 nonstuttering boys aged two, four, and six years were analyzed from tape recorded speech samples made during free play within neutral and stress situations. Comparisons of frequency of disfluency were made among the different ages within each situation and between the neutral and stress situations. (Author)

The Lidcombe Program is an operant treatment for early stuttering. Outcomes indicate that the program is effective; however, the underlying mechanisms leading to a successful reduction of stuttering remain unknown. The purpose of this study was to determine whether fluency achieved with the Lidcombe Program was accompanied by concomitant reduction…
