The pharyngeal, oral, and nasal cavities are components of the vocal tract (VT), which plays a crucial role in speech production. The pharynx, a shared space for respiratory and digestive functions, has three divisions:
1. Nasopharynx: Located behind the nasal cavity.
2. Oropharynx: Positioned behind the oral cavity (mouth).
3. Laryngopharynx: The lowermost part, connecting to the larynx and esophagus.
These divisions contribute to the resonance and articulation of sounds during speech.
