Monitoring vocal fold abduction through vocal fold contact area.
A number of commercial devices for measuring the transverse electrical conductance of the thyroid cartilage produce waveforms that can be useful for monitoring movements within the larynx during voice production, especially movements that are closely related to the time-variation of the contact between the vocal folds as they vibrate. This paper compares the various approaches that can be used ...
متن کاملare speech attractor models useful in diagnosing vocal fold pathologies?
the speech is an easily accessible signal which clearly represents the characteristics of larynx and vocal folds. therefore, application of some proper machine learning algorithms on a small part of a recorded speech signal may help in non-invasive diagnosing of vocal fold diseases. since there are some experimental evidences that suggest the existence of chaotic behavior in speech production s...
متن کاملThreshold Pressure For Vocal Fold Collision
Phonation threshold pressure (PTP) is frequently used for characterizing vocal fold vibration properties. However, because of the very low pressures, it is often difficult to measure PTP with acceptable accuracy. This investigation analyses an alternative pressure, the collision threshold pressure (CTP), defined as the lowest pressure required to initiate vocal fold collision. Fourteen amateur ...
متن کاملThreshold Pressure for Vocal Fold Collision
A new measurement has been investigated, called the collision threshold pressure (CTP), meaning the minimal pressure required to initiate vocal fold collision. The purpose was to find a measurement that would be more accurate and less time-consuming to collect than the presently used phonation threshold pressure (PTP). Fourteen amateur singers – six female and eight male – were measured using a...
متن کاملPaediatric vocal fold paralysis.
INTRODUCTION AND OBJECTIVES Vocal fold paralysis (VFP) is a relatively common cause of stridor and dysphonia in the paediatric population. This report summarises our experience with VFP in the paediatric age group. METHODS All patients presenting with vocal fold paralysis over a 12-month period were included. Medical charts were revised retrospectively. The diagnosis was performed by flexible...
