• Electroglottography (EGG) emerged as a noninvasive proxy for vocal fold contact, with studies validating its relation to glottal activity, refining interpretation, and applying it to clinical voice assessment. [2] [3] [15] [20]

• Articulatory-physiological modeling linked glottal dynamics to acoustics, using two-mass vocal cord representations and interconnected vocal-tract constraints to examine how laryngeal activity shapes voiced sounds. [1] [6] [5]

• Concurrent EGG data were cross-validated with direct observations of glottal contact via high-speed imaging and timing analyses, demonstrating concordance and clarifying what EGG reflects. [7] [15] [3] [20]

• Clinical/laryngeal assessment from EGG-derived features enables discrimination of pathology from normal voices using signal-processing analyses of simultaneous EGG and speech. [15] [2] [3]

• EGG-informed studies illuminate how subglottal pressure, airflow, and aerodynamic power relate to vocal intensity and f0, linking glottal contact to measurable aerodynamic outputs. [5] [16]
