In phonetics, the point or place of articulation is the area in the vocal system where contact or obstruction occurs that allows a sound to occur. Active and passive articulations exist.There are five types of active articulators: the lip, front of the tongue, middle/back of the tongue, and the root, together with the epiglottis and the larynx These articulators can be used independently or work
. together in coarticulation. Passive articulations occur somewhere between the active ones, in unnamed areas of the vocal system. For more on this topic, visit: http://en.wikipedia.org/wiki/Place_of_articulation
