Vocalization Subsystem Responses To A Temporarily Induced Unilateral Vocal Fold Paralysis, Daniel J. Croake
Theses and Dissertations--Rehabilitation Sciences
Healthy voicing is thought to be dependent on a dynamic balance of three interactive subsystems: respiration, phonation, and resonance. Theoretically, multiple patterns of subsystem interactions likely underlie healthy voice production; however surprisingly little quantitative data exists defining the nature of these subsystem production patterns and interactions across individuals.
The central aim of this study was to quantify the interactions of the vocalization subsystems in a non-perturbed and perturbed condition (induced unilateral vocal fold paralysis) in 10 vocally healthy participants. Respiratory inductance plethysmography, laryngeal aerodynamics, and acoustic formant data were used to measure the proportional contributions of, and changes to, the …
