The organs of the speech produce almost all the sounds needed for language. These organs are divided in 2:
Passive articulators: those which remain static during the articulation of sound. (Upper lips, upper teeth, alveolar ridge, hard palate, etc.)
Active articulators: those which move towards these passive articulators to produce various speech sounds in a different way. (Uvula, lower jaw, lower teeth, lower lips, etc., the most important active articulator is the tongue)
