[3] The term laryngeal is often taken to be synonymous with glottal, but the larynx consists of more than just the glottis (vocal folds): 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.
Symbols to the right in a cell are voiced, to the left are voiceless.
Shaded areas denote articulations judged impossible.
