Velaric ingressive

From Wikipedia, the free encyclopedia

In phonetics, velaric ingressive, sometimes called lingual ingressive, is an airstream mechanism where a sound is produced by a closure at two places of articulation, rarifying the air in the enclosed space by lowering the tongue, and then releasing both closures. Such sounds are more commonly known as clicks.

The front articulation may be coronal or, more rarely, labial. The rear articulation has traditionally been thought to be velar or, again more rarely, uvular, but recent investigation of Nǀuu has revealed that the supposed velar-uvular distinction is actually one of a simple click versus a click-plosive airstream contour, and that all rear articulations are uvular or even pharyngeal. Even in languages without such a distinction, such as Xhosa, experiments have shown that when the click release is removed from a recording, the resulting sound is judged to be uvular, not velar. However, other languages may have a velar articulation.

Since clicks are not necessarily velar, some phoneticians prefer the term lingual (made with the tongue) over velar (made with the velum) for such sounds.
