Geometry-Driven Whole-Larynx Phonation Paradigm

2011 - 2014

Between 2011 and 2014, the dominant pattern tied intraglottal flow dynamics and pressure distributions to wall-jet phenomena while expanding focus beyond the glottis to whole-larynx contributions, epilaryngeal shaping, and supraglottal constraints. Computational phonation work increasingly treated geometry and multi-layer vocal fold properties as primary determinants of vibratory modes and pressure fields, supported by targeted finite-element sensitivity studies and tissue layering models. Empirical data from in vivo high-speed imaging and normative endoscopic measurements anchored these models in realistic physiology, highlighting hydration and tissue mechanics as modulators of vibratory stability and particle transport.

A unified pattern across 2011–2014 studies linking intraglottal flow dynamics to pressure distributions, combining theory (two-mass models), velocity measurements, and wall-jet analyses to explain closing-phase phenomena and their acoustic consequences [1], [9], [5], [8], [13].

Computational phonation modeling emphasizes geometry and material layering as dominant determinants of vibratory modes and pressure fields, with finite-element sensitivity studies and multi-layer vocal fold models guiding simulation practices [3], [8], [13], [1].

Whole-larynx and epilaryngeal contributions to articulation and voicing surface as a distinct paradigm, integrating laryngeal features and aerodynamic constraints into phonology and speech production, broadening beyond glottal-centric views [4], [2], [18], [14].

Empirical measurement and normative datasets support model calibration, including canine intraglottal measurements, in vivo kinematics via high-speed endoscopy, and KayPENTAX system norms, anchoring aerodynamic phonation models in real-world data [7], [5], [9], [16], [10], [13].

Hydration and tissue mechanics intersect phonation with airway-flow considerations, where vocal fold hydration, tissue stresses, and upper-airway anatomy modulate vibratory behavior and particle transport, signaling an integrative physiologic-aerodynamic research direction [20], [14], [11].
