Flap consonant

In phonetics, a flap or tap is a type of consonantal sound, which is produced with a single contraction of the muscles so that one articulator is thrown against another. The main difference between a flap and a stop consonant is that in a flap, there is no buildup of air pressure behind the place of articulation.
