People say between 150 and 200 words a minute on average during a casual conversation.
The Speech Motor Neuroscience Group is seeking participants who are 18-90 years old, have good hearing, and have no history of stroke, brain injury, or neurological disease. Studies last 1-2 hours and can be scheduled …
Although movement variability is often attributed to unwanted noise in the motor system, recent work has demonstrated that variability may be actively controlled.
Speakers use auditory feedback to guide their speech output, although individuals differ in the magnitude of their compensatory response to perceived errors in feedback. Little is known about the factors that contribute to the compensatory response or how fixed or flexible they are within an individual. Here, we test whether manipulating the perceived reliability of auditory feedback modulates speakers’ compensation to auditory perturbations, as predicted by optimal models of sensorimotor control.
Schwa is cross-linguistically described as having a variable target. The present study examines whether speakers are sensitive to whether their auditory feedback matches their target when producing schwa.
Disorders of speech production may be accompanied by abnormal processing of speech sensory feedback. Here, we introduce a semi-automated analysis designed to assess the degree to which speakers use natural online feedback to decrease acoustic variability in spoken words.
