Abstract
A Study of the Correlation between Phonetic Parameters during Sustained Vowel and Speech Production with Benign Laryngeal Disorders
Highlights
Voice disorder may manifest itself through a change in voice quality from structural and/or physiological changes in the larynx, in addition to the symptoms presented by the patient and the impact of this disorder on their quality of life [1]
The results revealed that 1.96% (385/19636 adult subjects) were positive for abnormal findings with organic laryngeal disease, not taking into account other laryngeal pathologies, for example, paralysis recurrent laryngeal nerve, muscle tension dysphonia and spasmodic dysphonia, as well as laryngeal cancer [2]
This study is the first to quantify aerodynamic and acoustic parameters and perceptual evaluations of voice disorders in a speech laboratory. These results have potentially indicated that almost all parameters have some significant change on the threshold of pathology in mean values in the evaluative clinic setting
Summary
Voice disorder may manifest itself through a change in voice quality from structural and/or physiological changes in the larynx, in addition to the symptoms presented by the patient and the impact of this disorder on their quality of life [1]. The results revealed that 1.96% (385/19636 adult subjects) were positive for abnormal findings with organic laryngeal disease, not taking into account other laryngeal pathologies, for example, paralysis recurrent laryngeal nerve, muscle tension dysphonia and spasmodic dysphonia, as well as laryngeal cancer [2]. This finding highlights the demand for methods to comprehensively assess pathological voice at the initial stage of disease, and to track the outcomes of specific voice prevention, education, and treatment programs.
