As children age, they are less likely to experience spontaneous recovery from stuttering and are likely to develop negative attitudes about talking, necessitating counselling to address these feelings. The current exploratory case study examines children's response to traditional speech therapy to address fluency combined with a programmed message…

Participants of stuttering treatment programs provide an opportunity to evaluate persons who stutter as they demonstrate varying levels of fluency. Identifying physiologic correlates of altered fluency levels may lead to insights about mechanisms of speech disfluency. This study examined respiratory, orofacial kinematic and acoustic measures in 35…

The study compared speech naturalness ratings of 280 perceptually fluent speech samples produced by nonstutterers and stutterers who had been treated in six different therapy programs. A significant difference existed between the naturalness ratings of nonstutterers and the treated stutterers. No difference was found in the posttreatment…

This study investigated the disfluencies and phonic tics in an 18- year-old male with Tourette syndrome before and after a 3-week period of speech therapy. The subject's speech pattern did not completely conform to the classic pattern of stuttering but bore more resemblance to cluttering. A limited number of therapy sessions resulted in a…

A rating instrument is described that can be used to assess the results of stuttering treatments. The instrument yields a comprehensive and detailed description of speech quality in terms of articulation, phonation, pitch, and loudness, as well as naturalness. Psychometric characteristics of the instrument are analyzed, and methodological problems…

The study of 35 posttreatment stutterers found that magnitude estimation and interval scaling were both valid procedures for measuring speech naturalness. Speech of nonstutterers was judged more natural than speech of treated stutterers. The acoustic parameters most highly correlated with speech naturalness were voice onset time measure and…
