Effects of Vocal Fold Nodules on Glottal Cycle Measurements Derived from High-Speed Videoendoscopy in Children.
The goal of this study is to quantify the effects of vocal fold nodules on vibratory motion in children using high-speed videoendoscopy. Differences in vibratory motion were evaluated in 20 children with vocal fold nodules (5-11 years) and 20 age and gender matched typically developing children (5-11 years) during sustained phonation at typical pitch and loudness. Normalized kinematic features ...
متن کاملBiomechanical simulation of vocal fold dynamics in adults based on laryngeal high-speed videoendoscopy
MOTIVATION Human voice is generated in the larynx by the two oscillating vocal folds. Owing to the limited space and accessibility of the larynx, endoscopic investigation of the actual phonatory process in detail is challenging. Hence the biomechanics of the human phonatory process are still not yet fully understood. Therefore, we adapt a mathematical model of the vocal folds towards vocal fold...
متن کاملAutomated measurement of vocal fold vibratory asymmetry from high-speed videoendoscopy recordings.
PURPOSE In prior work, a manually derived measure of vocal fold vibratory phase asymmetry correlated to varying degrees with visual judgments made from laryngeal high-speed videoendoscopy (HSV) recordings. This investigation extended this work by establishing an automated HSV-based framework to quantify 3 categories of vocal fold vibratory asymmetry. METHOD HSV-based analysis provided for cyc...
متن کاملQuantitative Measurement of Vocal Fold Vibration in Male Radio Performers and Healthy Controls Using High-Speed Videoendoscopy
PURPOSE Acoustic and perceptual studies show a number of differences between the voices of radio performers and controls. Despite this, the vocal fold kinematics underlying these differences are largely unknown. Using high-speed videoendoscopy, this study sought to determine whether the vocal vibration features of radio performers differed from those of non-performing controls. METHOD Using h...
متن کاملEffect of vocal fold asymmetries on glottal flow.
OBJECTIVES/HYPOTHESIS Voice disorders, such as unilateral vocal fold paralysis or paresis, and vocal fold scarring feature structural asymmetries of the vocal folds. Studies on how structural asymmetries affect voice has mostly been limited to computational simulations and experiments on mechanical models. The purpose of the current study is to examine the effects of asymmetries in left-right p...
