Improvement of Vocal Pathologies Diagnosis Using High-Speed Videolaryngoscopy
Introduction The study of the dynamic properties of vocal fold vibration is important for understanding the vocal production mechanism and the impact of organic and functional changes. The advent of high-speed videolaryngoscopy (HSV) has provided the possibility of seeing the real cycle of vocal fold vibration in detail through high sampling rate of successive frames and adequate spatial resolu...
متن کاملObjective vocal fold vibration assessment from videokymographic images
Vocal folds oscillation crucially influences all the basic qualities of voice, such as pitch and loudness, as well as the spectrum. Stroboscopy provides the standard view of the larynx. Videokymography is a new diagnostic tool developed to overcome specific limitations of stroboscopy in severely dysphonic patients with an aperiodic signal. It registers the movements of the vocal folds with a hi...
متن کاملVideokymography: a New High-Speed Method for the Examination of Vocal-Fold Vibrations
Videokymography is a new optical high-speed method for investigation of vibrations which was developed especially for examination of vocal-fold vibrations. Videokymography is based on a modified CCD video camera, which is able to work in two different modes: standard and high-speed. In the standard mode the camera works as a normal commercial video camera providing 25 images (50 interlaced fiel...
متن کاملMeasurement of the vocal-fold vibration behaviour in excised human larynges
The contribution presents information on the experimental investigation of the glottal sound source with excised human larynges. The vocal fold vibrations were excited by airflow and monitored acoustically, electroglottographically as well as by means of laser vibrometry, pressure transducers, videokymography and stroboscopy techniques. The paper is focused on 1) presenting a method for monitor...
متن کاملEffects of Hydration on Voice Acoustics
ABSTRACT: Purpose: Caring for the professional voice involves an understanding of the aspects of vocal function and the aspects affecting vocal function. The significance of the voice is especially obvious for individuals whose careers rely on speech. Clinical advice and support programs to improve voice conditions for professional voice users should be based on a foundation of empirical resear...
