QUANTIFICATION OF GLOTTAL WIDTH VIA VIDEOKYMOGRAPHIC AND HIGH SPEED IMAGES WITH BIDIRECTIONAL ILLUMINATION

Popis výsledku v původním jazyce

Laryngeal image assessment techniques have evolved from the initial endeavours to observe the vibration of the vocal folds in slow motion by means of stroboscopy through to the implementation of state-of-art high-speed video (HSV) devices. Among other renowned laryngeal visualization methods, Videokymography (VKG) has shown to provide a practical and efficient way to visualize a number of important features of the vocal fold vibration. A secondary light source was placed at the level of the cricothryroid space in addition to conventional VKG and HSV light sources (i.e. above the glottis). The participants were asked to sustain a series of different pitches whilst producing an [i:] vowel. The secondary light source was manually removed from the participant?s neck during a single sustained phonation, hence images were obtained with BI and traditional illumination for the same phonation. The present implementation of a bidirectional illumination setup for VKG and HSV highlights the possib
