Journal of Phonetics, 2001
Abstract The earliest models of phonation were based on the assumption that the glottis is closed during a part of the vibration cycle, that is, the phonation is modal. Nonmodal phonation, however, commonly occurs not only for disordered voice but also for normal voices, which often exhibit a breathy quality or irregular vibration.

Acta Otorrinolaringologica (English Edition), 2007
To describe our experience with the use of trachea-oesophageal puncture (TEP) after total laryngectomy.We have studied retrospectively 96 patients who received a voice prosthesis through tracheoesophageal puncture between October 2000 and December 2005.The punctures effected were 86 primary (89.6 %) and 10 secondary (10.4 %); of the prostheses, 81 (84 ...

An aeroacoustic approach to phonation
The Journal of the Acoustical Society of America, 1988A fluid mechanical, or aeroacoustic, point of view is followed to study possible sources of sound during phonation. Concentration is on two features of the vocal tract during phonation: abrupt area change from the glottis to the vocal tract and the finite length of the vocal tract.

Phonation threshold pressure measurements during phonation by airflow interruption
The Laryngoscope, 1999AbstractObjective/Hypothesis: Most methods to measure phonation threshold pressure (PTP) are clinically impractical because they are invasive. This report concerns an airflow interruption system developed to allow noninvasive estimation of (PTP) at different levels of vocal intensity.

Disorders of phonation in children
Pediatric Clinics of North America, 2003Vocal disturbances in children are surprisingly common. Typical pathologic conditions differ, however, from those that are seen commonly in adults. Disturbances in the vibratory characteristic of the vocal folds cause dysphonia. The most common causes for dysphonia are infectious, anatomic, congenital, inflammatory, neoplastic, neurologic, or ...

Nerve‐Induced Rabbit Phonation: Temporal Phonation Stability
Otolaryngology–Head and Neck Surgery, 2008ProblemIn‐vivo phonation using animals with layered structure similarities and phonation characteristics akin to humans are needed for the study of vocal fold reparative processes. The authors’ previous studies have demonstrated the feasibility of eliciting vocalization in a flow‐controlled in‐vivo rabbit preparation.

Swallowing, phonation, and articulation
2016The final common pathway related to swallowing (deglutition), phonation (vocalization), and articulation involves the ninth cranial nerve (glossopharyngeal nerve), the 10th cranial nerve (vagus nerve), and the 12th cranial nerve (hypoglossal nerve). This chapter explains the symptoms and signs caused by impairment of this system.

Mechanical stress in phonation
Journal of Voice, 1994Mechanical stress is always encountered in phonation. This includes tensile stress, shear stress, impact stress during collision, maximum active contractile stress in laryngeal muscles, inertial stress, and aerodynamic stress (pressure). Order of magnitude calculations reveal that tensile stress can reach the greatest value (near 1.0 MPa), contractile ...
