A methodological study of hemilaryngeal phonation
The Laryngoscope, 1993AbstractAn excised hemilarynx setup was developed. The phonatory characteristics of nine excised canine larynges were examined. The left vocal fold of each larynx was then removed and substituted with a vertical plexiglass plate. The larynges were phonated again.

Determination of Phonation Instability Pressure and Phonation Pressure Range in Excised Larynges
Journal of Speech, Language, and Hearing Research, 2007PurposeThe present study was a methodological study designed to reveal the dynamic mechanisms of phonation instability pressure (PIP) using bifurcation analysis. Phonation pressure range (PPR) was also proposed for assessing the pressure range of normal vocal fold vibrations.MethodThe authors first introduced the concept of bifurcation on the basis of ...

Vocal efficiency in tracheoesophageal phonation
Auris Nasus Larynx, 2008Voice rehabilitation after total laryngectomy is challenging. In order to investigate and understand the function of the neoglottis sophisticated measurements need to be made. During voice production, aerodynamic energy is transformed into sound energy.

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.

Nutzung nonkommunikativer Phonation
2015Nonkommunikative Phonation ist aufgrund ihrer lebenserhaltenden Primarfunktion stabiler und weniger storungsanfallig. Daruber hinaus kann sie in der Therapie spielerisch eingesetzt werden, ist nicht leistungsorientiert, sondern weckt die Experimentierfreude mit der Stimme.

The sounds of speech are produced by the exhaled air from the lungs associated with changes of the true vocal cords to produce phonation. Further, exhaled air undergoes modifications in the “vocal tract”—the spaces and passages above the larynx—so that noises such as bursts and hisses produce the voiceless aspects of speech.

Breathing Mechanics and Phonation
1980We have now devoted five chapters to a discussion of morphology and function, a discussion necessary to any depth of understanding of the human voice. Now we must go on to the application of that information to the problems of speech and song. In this chapter our purpose is to examine the modifications of the process of breathing necessary for normal ...

Geometric dependence of phonation threshold pressure and phonation onset frequency.
The Journal of the Acoustical Society of America, 2009Dependence of phonation threshold pressure and phonation onset frequency on vocal fold geometry was numerically investigated in a continuum model of the vocal folds. The geometric parameters of interest include the medial surface thickness, vocal fold depths of the body, and cover layers.
