Purpose: The purpose of this study was to test whether adults who stutter (AWS) display a different range of sensitivity to delayed auditory feedback (DAF). Two experiments were conducted to assess the fluency of AWS under long-latency DAF and to test the effect of short-latency DAF on speech kinematic variability in AWS. Method: In Experiment 1,…

Language skills have long been posited to be a factor contributing to developmental stuttering. The current study aimed to evaluate whether novel word recognition, a critical skill for language development, differentiated children who stutter from children who do not stutter. Twenty children who stutter and 18 children who do not stutter, aged 3-8…

Stuttering is a developmental speech disorder characterized by interruptions of fluency. A large body of research suggests that stuttering occurs due to a reduced ability to generate timing signals in order to sequence speech sounds. One piece of supporting evidence for this is that when speaking along with an external timing source like a…

Purpose: Phonological skills have been associated with developmental stuttering. The current study aimed to determine whether the neural processes underlying phonology, specifically for nonword rhyming, differentiated stuttering persistence and recovery. Method: Twenty-six children who stutter (CWS) and 18 children who do not stutter, aged 5…

Background: Numerous studies have demonstrated the benefit of devices delivering altered auditory feedback (AAF) as a therapeutic alternative for those who stutter. Aims: The effectiveness of a device delivering AAF (SpeechEasy®) was compared with behavioural techniques in the treatment of stuttering in a randomized clinical trial. Methods &…
