Speech Motor Control in Younger and Older Adults: The Effect of Age and Individual Differences on Speech Error Production
… dissertation investigates three main issues in speech motor control, all of which are explored through the lens of speech error production. The speech error elicitation task used is the alternating onset, identical coda (e.g. ‘top cop’) paradigm, which in this incarnation is executed in time to …

The application of linear and nonlinear estimators of acoustic variability in the assessment of speech motor control in hypokinetic dysarthria
… measures in the assessment and treatment of speech disorders, researchers and clinicians are always in search of new techniques to quantify speech impairment. This thesis investigates the relatively unexplored area of linear and nonlinear estimators of acoustic variability and their …

Auditory-motor integration influences on speech motor control and fluency: a comparison of normally fluent speakers and people who stutter
… effects of delayed auditory feedback (DAF) on speech motor stability and speech fluency in normally fluent adults (PWNS) and to compare them with effects on adults who exhibit persistent stuttering. If the auditory processing influences differently the two groups, it might shed light on the …

Assessing functional links between speech production and perception in multilingual speakers
The relationship between speech production and speech perception capacities is highly debated. The picture is complicated further by studies of second language acquisition, where development of speech perception is not always accompanied by proportional gains in speech production, and vice versa. …

Identification of Traits Transmitted Associated With Stuttering
… between the stuttering, high-risk and control groups on two of the tapping tasks. Other interesting trends were apparent although they did not reach statistical significance, partially because of the small number of participants resulting in low power values. These trends indicated that …

Effects of Delayed Auditory Feedback on the Bereitschaftspotential
… the preparatory state of a person prior to motor execution of an act and can be observed 1500 to 500 ms prior to voluntary movement. The participants in the study included 10 adults with normal speech. Each read a series of 30 sentences, both without DAF and with DAF, while the BP was …

Adaptive auditory-motor control of the time-varying formant trajectories in vowels and its patterns of generalization
… that auditory feedback-based learning and control of speech movements is not restricted to quasi-static gestures in monophthongs as found in previous studies, but also extends to time-varying gestures. To probe the internal structure of the mechanisms of auditory-motor transformations in …

Characterization of phoneme rate as a vocal biomarker of depression
… scalable indicators of a disorder. A person's speech is a rich source of neurocognitive information because speech production is a complex sensorimotor task that draws upon many cortical and subcortical regions. Furthermore, the ease of collection makes speech a practical, scalable candidate …

The articulatory basis of positional asymmetries in phonological acquisition
… effects will cease to apply. Because children's speech-motor control capabilities are known to diverge from those of the skilled adult speaker, it is posited that articulatory factors play the dominant role in shaping child-specific phonological processes. Here it is argued that children have …

The control of speech motor targets
Studies of speech production and its control have traditionally focused on acoustic parameters and/or articulatory configurations of the end result of the production process as the target of speech production. The representations of production target, however, are far richer than the stereotypical …

Online control of articulation based on auditory feedback in normal Speech and stuttering : behavioral and modeling studies
Articulation of multisyllabic speech requires a high degree of accuracy in controlling the spatial (positional) and the temporal parameters of articulatory movements. In stuttering, a disorder of speech fluency, failures to meet these control requirements occur frequently, leading to dysfluencies …

EEG activation patterns in the frontal lobes of stutterers and nonstutterers during working memory tasks
… stuttering is a physiological disorder of speech motor control. Unlike acquired conditions, developmental stuttering is responsive to fluency-inducing conditions involving the manipulation or elimination of auditory feedback. It was hypothesized that stutterers experience interference …
