aryepiglottic การใช้

They are strongly pharyngealized, and for some speakers involve low-frequency trilling that presumably involves the aryepiglottic fold.
Pharyngeal or epiglottal stops and trills are usually produced by contracting the aryepiglottic folds of the larynx against the epiglottis.
The key to twang quality is a narrowing of the epilarynx via a narrowing or constriction of the aryepiglottic sphincter.
The amplification of these particular harmonics is believed to be a result of a narrowing of the Aryepiglottic fold just above the larynx.
The aryepiglottic muscle together with the transverse arytenoid and the thyroarytenoid work as a sphincter and close the larynx as we swallow or cough.
