“…This may be important to understanding F 0 characteristics because it has been hypothesized that forces exerted on the cartilages by the extrinsic laryngeal muscles may play a role in the regulation of F 0 by changing the geometry of the laryngeal framework and hence of the vocal folds. 13,[55][56][57] The vocal folds of older people, viewed laryngoscopically, commonly look distinctly different from those of younger people. There is frequently grayish or yellowish discoloration of the tissue, loss of mass, and a residual gap (perhaps of unusual shape) on vocal fold adduction.…”

“…Others think that it was the airway-opening, which allowed for quick and increased air intake for sprinting and endurance running [ 48 ]. This view is supported the spring-like recoiling structures in the larynx [ 49 ] that seem to favour airway-opening over airway-closing. What links this discussion to the present study is that the laryngeal axis of constriction, i.e., airway-opening and airway-closing, and the laryngeal axis of height, i.e., vertical larynx movement, have been noted to be interdependent [ 42 ].…”

Intrinsic velocity differences between larynx raising and larynx lowering

In this study, 23 subjects produced cyclic transitions between rounded vowels and unrounded vowels as in /o-i-o-i-o-…/ at two specific speaking rates. Rounded vowels are typically produced with a lower larynx position than unrounded vowels. This contrast in vertical larynx position was further amplified by producing the unrounded vowels with a higher pitch than the rounded vowels. The vertical larynx movements of each subject were measured by means of object tracking in laryngeal ultrasound videos. The results indicate that larynx lowering was on average 26% faster than larynx raising, and that this velocity difference was more pronounced in woman than in men. Possible reasons for this are discussed with a focus on specific biomechanical properties. The results can help to interpret vertical larynx movements with regard to underlying neural control and aerodynamic conditions, and to improve movement models for articulatory speech synthesis.

“…Another weakness concerns the general coarseness of the laryngeal mucosa and the lack of deformability of the laryngeal cartilages. This made it difficult to simulate in fine detail the contact occurring between the corniculate tubercles, which in real life undergo considerable deformation-a property that has been attributed considerable functional significance by Fink (1974b). Last, it must be acknowledged that although ArtiSynth represents a significant achievement in terms of numerical stability combined with efficient computation of such complex dynamics, there are still many cases that simply cannot be simulated because of numerical instability or outright crashes.…”
