Assessing progress of Parkinson's disease using acoustic analysis of phonation [PDF]
International Conferences and Workshop on Bioinspired Intelligence, 2015 This paper deals with a complex acoustic analysis of phonation in patients with Parkinson's disease (PD) with a special focus on estimation of disease progress that is described by 7 different clinical scales (e. g.

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.

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 the Acoustical Society of America, 2017 Although stiffness conditions in the multi-layered vocal folds are generally considered to have a large impact on voice production, their specific role in controlling vocal fold vibration and voice acoustics is unclear.

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 ...

Comparing Measures of Voice Quality From Sustained Phonation and Continuous Speech.
Journal of Speech, Language and Hearing Research, 2016 Purpose The question of what type of utterance-a sustained vowel or continuous speech-is best for voice quality analysis has been extensively studied but with equivocal results.

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 ...

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.

Journal of Speech, Language and Hearing Research, 2017 Purpose The purpose of this study was to determine the short-term effect of 2 semi-occluded vocal tract training programs, "resonant voice training using nasal consonants" versus "straw phonation," on the vocal quality of vocally healthy future ...

Precision‐Optimised Post‐Stroke Prognoses
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Current medicine cannot confidently predict who will recover from post‐stroke impairments. Researchers have sought to bridge this gap by treating the post‐stroke prognostic problem as a machine learning problem, reporting prediction error metrics across samples of patients whose outcomes are known.
