Characteristics of disfluency clusters in adults who stutter.

Disfluency clusters of children who stutter: relation of stutterings to self-repairs.

The purpose of this study was to account for the frequency, type, and possible origins of speech disfluency clusters in the spontaneous speech of 3- to 6-year-old children, 30 who stutter and 30 who do not stutter. On the basis of the Covert Repair Hypothesis (Postma & Kolk, 1993), which suggests that stutterings are the by-products of self-repairs or self-corrections of speech errors, three hy...

Judgment of disfluency in people who stutter and people who do not stutter: results from magnitude estimation.

Two experiments used a magnitude estimation paradigm to test whether perception of disfluency is a function of whether the speaker and the listener stutter or do not stutter. Utterances produced by people who stutter were judged as "less fluent," and, critically, this held for apparently fluent utterances as well as for utterances identified as containing disfluency. Additionally, people who st...

Cortical dynamics of disfluency in adults who stutter

Stuttering is a disorder of speech production whose origins have been traced to the central nervous system. One of the factors that may underlie stuttering is aberrant neural miscommunication within the speech motor network. It is thus argued that disfluency (any interruption in the forward flow of speech) in adults who stutter (AWS) could be associated with anomalous cortical dynamics. Aberran...

Simulations of the types of disfluency produced in spontaneous utterances by fluent speakers, and the change in disfluency type seen as speakers who stutter get older

The EXPLAN model is implemented on a graphic simulator. It is shown that it is able to produce speech in serial order and several types of fluency failure produced by fluent speakers and speakers who stutter. A way that EXPLAN accounts for longitudinal changes in the pattern of fluency failures shown by speakers who stutter is demonstrated.
