Articulation

Every speech sound is defined by three properties: its class (consonant, vowel, or tone), its place of articulation (where in the vocal tract it is formed — lips, teeth, palate, etc.), its manner (how airflow is controlled — stopped, funneled into a fricative, channeled through the nose), and its voicing (whether the vocal cords vibrate during production).
