[Help] An obstruent is a consonant sound formed by obstructing airflow, causing increased air pressure in the vocal tract, such as [k], [d͡ʒ] and [f]. In phonetics, articulation may be divided into two large classes: obstruents and sonorants.
Obstruents are those articulations in which there is either a total closure of the vocal tract, or a partial closure, i.e. a stricture causing friction, both groups being associated with a noise component.
Obstruents are subdivided into stops (with total closure followed by an "explosive" release of air – hence the equivalent term plosive), affricates (with at first a stop-like total closure, followed by a more controlled, fricative-style release, i.e. a stricture causing friction), and fricatives (with only limited closure, i.e. no more than a steady stricture causing friction). Obstruents are prototypically voiceless, though voiced obstruents are common. This contrasts with sonorants, which are much more rarely voiceless.
