Assessment of the effect of supine posture and phonation on modified mallampati grading and its applicability in prediction of difficult airway

Journal of Mahatma Gandhi Institute of Medical Sciences, 2018
Introduction: As it is not always possible to do Modified Mallampati Test (MMT) in sitting position, this study was designed to test the effect of supine position and phonation on classical MMT and use of such effect in predicting difficult ...

Detecting Parkinson’s disease from sustained phonation and speech signals

PLoS ONE, 2017
This study investigates signals from sustained phonation and text-dependent speech modalities for Parkinson’s disease screening. Phonation corresponds to the vowel /a/ voicing task and speech to the pronunciation of a short sentence in Lithuanian ...

Vocal instabilities in a three-dimensional body-cover phonation model.

Journal of the Acoustical Society of America, 2018
The goal of this study is to identify vocal fold conditions that produce irregular vocal fold vibration and the underlying physical mechanisms. Using a three-dimensional computational model of phonation, parametric simulations are performed with co ...

Computational modeling of vibration-induced systemic hydration of vocal folds over a range of phonation conditions [PDF]

, 2014
Predicting phonation conditions that are benign to voice health remains a biomechanically relevant problem.Our objective is to provide insight into vocal fold (VF) hydration based on continuum-based VF models thatare able to compute VF stresses during ...

Characterizing intonation deficit in motor speech disorders : an autosegmental-metrical analysis of spontaneous speech in hypokinetic dysarthria, ataxic dysarthria and foreign accent syndrome [PDF]

, 2012
The autosegmental-metrical (AM) framework represents an established methodology for intonational analysis in unimpaired speaker populations but has found little application in describing intonation in motor speech disorders (MSDs).
