Articulatory Kinematics During Stop Closure In Speakers With Parkinson’S Disease, Austin Ross Thompson
LSU Master's Theses
Purpose: The goal of this exploratory study was (a) to investigate the differences in articulatory movements during the closure phase of bilabial stop consonants with respect to distance, displacement, and timing of motion between individuals with Parkinson’s Disease (PD) and healthy controls; and (b) to investigate changes in articulatory movements of speakers with PD when they voluntarily vary the degree of speech intelligibility.
Methods: Six participants, 4 PD and 2 healthy control (HC) speakers, participated in this study. The stimulus was a sentence containing several bilabial stop consonants (i.e., “Buy Bobby a puppy”). Movement data were collected using …
