What term describes a sound produced by forcing air through a narrow channel formed by the lips, teeth, or tongue, as in /θ/?

Explanation:
Fricative. Fricatives are produced by forcing air through a narrow constriction in the vocal tract, creating continuous turbulence and a hissing-like sound. The channel can be formed by the lips, teeth, or tongue against the teeth or palate, which matches the description. The example /θ/ is a dental fricative (air flowing between the tongue and teeth), typically voiceless in English. This differs from plosives (complete oral closure with a burst), nasals (air through the nasal cavity), and affricates (a stop release followed by a fricative).
