Vocal Fold and False Vocal Fold Vibrations in Throat Singing and Synthesis of Khöömei
We observed laryngeal movements in throat singing using physiological methods: the simultaneous recording of singing sounds, EGG, and high-speed digital images. We observed vocal fold and false vocal fold vibration and estimated the vibration patterns. We also estimated the laryngeal voices by using an inverse filtering method and simulated the vibration pattern using a new physical model: 2× 2...
متن کاملPersistent Dysphonia after Laryngomicrosurgery for Benign Vocal Fold Disease
OBJECTIVES Laryngomicrosurgery (LMS) is used to manage most vocal fold lesions. However, the functional voice outcome of the LMS might be diverse due to the influence of various factors. We intend to evaluate the incidence and etiologic factors of persistent dysphonia after LMS for benign vocal fold disease (BVFD). METHODS We performed a retrospective review of 755 patients who underwent LMS ...
متن کاملModal analysis of vocal fold vibrations using laryngotopography
In this paper, we propose a method for analyzing spatial characteristics of the larynx during phonation by high-speed digital imaging. The laryngotopography was applied to the high-speed digital images of normal subjects, and patients with paralysis and cyst. The results show various modes of vibration of the vocal folds particular to the patients with paralysis and cyst and usefulness of the l...
متن کاملDysphonia secondary to traumatic avulsion of the vocal fold in infants.
OBJECTIVE Airway compromise due to paediatric intubation injuries is well documented; however, intubation injuries may also cause severe voice disorders. We report our experience and review the world literature on the voice effects of traumatic paediatric intubation. CASE SERIES We report five cases of children referred to Great Ormond Street Hospital for Children who suffered traumatic avuls...
متن کاملObjective dysphonia quantification in vocal fold paralysis: comparing nonlinear with classical measures.
Clinical acoustic voice-recording analysis is usually performed using classical perturbation measures, including jitter, shimmer, and noise-to-harmonic ratios (NHRs). However, restrictive mathematical limitations of these measures prevent analysis for severely dysphonic voices. Previous studies of alternative nonlinear random measures addressed wide varieties of vocal pathologies. Here, we anal...
