Quantitative 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 کاملObjective comparison of the electroglottogram to synchronous high-speed images of vocal-fold contact during vibration
This study investigated vocal-fold contact characteristics through electroglottography (EGG) and related them to vibratory behavior as seen through high-speed videoendoscopy (HSV). When the EGG cycle was broken down into phases, the contacting phase represented an increasing percentage of the whole cycle as the EGG signal moved through three registers (pulse, modal, and falsetto). Conversely, t...
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 کاملEffects 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 کاملInvestigating acoustic correlates of human vocal fold vibratory phase asymmetry through modeling and laryngeal high-speed videoendoscopy.
Vocal fold vibratory asymmetry is often associated with inefficient sound production through its impact on source spectral tilt. This association is investigated in both a computational voice production model and a group of 47 human subjects. The model provides indirect control over the degree of left-right phase asymmetry within a nonlinear source-filter framework, and high-speed videoendoscop...
