Modal locking between vocal fold and vocal tract oscillations
The human vocal folds are known to interact with the vocal tract acoustics during voiced speech production; namely a nonlinear sourcefilter coupling has been observed both by using models and in in vivo phonation. These phenomena are approached from two directions in this article. We first present a computational dynamical model of the speech apparatus that contains an explicit filter-source fe...
متن کامل[Incidence of structural vocal fold abnormalities associated with vocal fold polyps.
UNLABELLED Phonotrauma is considered the main cause of vocal fold polyps (VFP). However, the authors believe that an underlying anatomical deviation could render the vocal folds more susceptible to such trauma. AIM To prove this hypothesis a retrospective chart review was carried out to correlate the surgical findings of patients with VFP. MATERIAL AND METHODS The charts of thirty-three pat...
متن کاملThree-dimensional characteristics of the larynx with immobile vocal fold.
OBJECTIVES To evaluate the 3-dimensional (3-D) characteristics of the laryngeal lumen in patients with unilateral vocal fold immobility (UVFI) during phonation with the aid of multislice helical computed tomography (MSHCT). DESIGN A retrospective study. SETTING University hospital. Subjects Thirty-seven patients with UVFI. INTERVENTIONS Each subject was asked to sustain the vowel /a/ and ...
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...
