In phonetics,
articulation
may be divided into two large classes, obstruents and sonorants.
An obstruent is a consonant
sound formed by obstructing outward airflow, causing
increased air pressure in the vocal tract.
Obstruents are those articulations in which there
is a total closure or a stricture causing friction,
both groups being associated with a noise component; in
this class there is a distinctive opposition between voiceless
and voiced
types.
Obstruents are subdivided into stops,
fricatives,
and affricates.
Obstruents are prototypically voiceless,
though voiced obstruents are common. This contrasts with
sonorants,
which are rarely voiceless.
