- -The sound source is modified by the vocal tract, which acts as a sound filter
-

- – Tongue
- • Tip, blade, dorsum, root• Epiglottis
- – Jaw (mandible)
- – Velum (soft palate)
- – Lips/cheeks
- – Larynx/hyoid bone
-
Immobile/Passive Articulators
- – Alveolar ridge
- – Hard palate
- – Teeth
- – Posterior pharyngeal wall
-
