Laryngeal consonant
Laryngeal consonants are consonants with their primary articulation in the larynx. The laryngeal consonants comprise the pharyngeal consonants, the glottal consonants, and for some languages uvular consonants.
The term laryngeal is often taken to be synonymous with glottal, but the larynx consists of more than just the glottis : it also includes the epiglottis and aryepiglottic folds. In a broad sense, therefore, laryngeal articulations include the radical consonants, which involve the root of the tongue. The diversity of sounds produced in the larynx is the subject of ongoing research, and the terminology is evolving.
The term laryngeal consonant is also used for laryngealized consonants articulated in the upper vocal tract, such as Arabic 'emphatics' and Korean 'tense' consonants.
