Journal of Mazandaran University of Medical Sciences, 2020 Background and purpose: Airway assessment is very important in anesthesia. The aim of this study was to determine the diagnostic value of Mallampati test indicators in supine and sitting positions with and without phonation in anesthesia candidate ...

Quantification of acute vocal fold epithelial surface damage with increasing time and magnitude doses of vibration exposure. [PDF]
PLoS ONE, 2014 Because the vocal folds undergo repeated trauma during continuous cycles of vibration, the epithelium is routinely susceptible to damage during phonation.

Recovering implicit pitch contours from formants in whispered speech [PDF]
arXiv, 2023 Whispered speech is characterised by a noise-like excitation that results in the lack of fundamental frequency. Considering that prosodic phenomena such as intonation are perceived through f0 variation, the perception of whispered prosody is relatively difficult.

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).

Anatomical and spectrographic analysis of the voice in disease: A report of five cases
South African Journal of Communication Disorders, 1973 Five cases are presented. One is a case of ventricular phonation of iatrogenic origin and the remaining four had undergone laryngectomy for carcinoma of the larynx. Points of interest are discussed, particularly the constant ventricular fold phonation of

Journal of Biomechanical Science and Engineering, 2006 Oscillation of the vocal folds makes a sound source of the human voiced sound. Understanding of the oscillation mechanism, which is a complex flow-structure interaction problem in the airway, is crucial for considering clinical diagnosis of voice ...

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 ...

Characteristics of tracheostomy phonation valves [PDF]
European Respiratory Journal, 2006 Phonation valves are commonly used devices that allow the restoration of speech in tracheostomised patients. However, their use should not compromise the physiological benefit of tracheostomy.Six commercialised phonation valves were studied in a dynamic set-up simulating a respiratory frequency of 20 breaths·min−1, a tidal volume of 0.5 L and a peak ...

Aerodynamic Analysis Of Voice In Persons With Laryngopharyngeal Reflux [PDF]
, 2009 Objectives of the study: The individuals with laryngopharyngeal reflux are prone for aspiration of refluxed contents and so there is a need for aerodynamic evaluation in these individuals.

Speech and language therapy versus placebo or no intervention for speech problems in Parkinson's disease [PDF]
, 2012 Parkinson's disease patients commonly suffer from speech and vocal problems including dysarthric speech, reduced loudness and loss of articulation. These symptoms increase in frequency and intensity with progression of the disease).
