Glottal and epiglottal (pharyngeal) articulations, including sounds native to Arabic and canonical profiles, are examined to determine the levels of laryngeal stricture and muscular synergy involved in their production. An array of laryngeal manners of articulation is tested using video and high-speed laryngoscopic filming to identify active glottal, ventricular, and aryepiglottic processes. The focus is on the ventricular level of laryngeal control, which has not been adequately described in the literature. Glottal stop is shown to depend on the ventricular level; the LCA, LTA, AE, TE, and VEN muscles are implicated in ventricular and aryepiglottic adjustments; and the vibratory patterns of aryepiglottic trilling are described.
