Sub-apical In articulatory phonetics, the<unk>  (also point of<unk>  of a consonant is the point of contact where an obstruction occurs in the vocal tract between an active articulator (typically some part of the tongue), and a passive location (typically some part of the roof of the mouth). Active articulators are so named because they are capable of voluntary movement, while passive articulators are so called because they are normally fixed and are the parts with which the active articulator makes contact. Along with the manner of<unk>  and phonation, the<unk>  gives the consonant its distinctive sound. The terminology in this article has been developed for precisely describing all the consonants in all the world's spoken languages. No known language distinguishes all of the<unk> s described here so less precision is needed to distinguish the sounds of a particular language.
