Characteristics of Speech Mechanism and Motor Abilities in Adults Who Stutter

Comparison of different speech tasks among adults who stutter and adults who do not stutter

OBJECTIVES In this study, we compared the performance of both fluent speakers and people who stutter in three different speaking situations: monologue speech, oral reading and choral reading. This study follows the assumption that the neuromotor control of speech can be influenced by external auditory stimuli in both speakers who stutter and speakers who do not stutter. METHOD Seventeen adult...

Auditory-motor adaptation is reduced in adults who stutter but not in children who stutter.

Previous studies have shown that adults who stutter produce smaller corrective motor responses to compensate for unexpected auditory perturbations in comparison to adults who do not stutter, suggesting that stuttering may be associated with deficits in integration of auditory feedback for online speech monitoring. In this study, we examined whether stuttering is also associated with deficiencie...

Investigating speech motor practice and learning in people who stutter.

UNLABELLED In this exploratory study, we investigated whether or not people who stutter (PWS) show motor practice and learning changes similar to those of people who do not stutter (PNS). To this end, five PWS and five PNS repeated a set of non-words at two different rates (normal and fast) across three test sessions (T1, T2 on the same day and T3 on a separate day, at least 1 week apart). The ...

Neurocorrelates of speech-motor planning and execution in adults and children who stutter

Speech and nonspeech sequence skill learning in adults who stutter.

UNLABELLED Two studies compared the speech and nonspeech sequence skill learning of nine persons who stutter (PWS) and nine matched fluent speakers (PNS). Sequence skill learning was defined as a continuing process of stable improvement in speed and/or accuracy of sequencing performance over practice and was measured by comparing PWS's and PNS's performance curves of accuracy, reaction time, an...
