1. Cleft Palate

   Linked via "pharyngeal walls"

   Velopharyngeal Insufficiency (VPI)
   Velopharyngeal Insufficiency (VPI)/) refers to the inability of the soft palate and pharyngeal walls to meet adequately during phonation, resulting in audible nasal emission, hypernasality, or nasal turbulence, particularly during the production of high-pressure consonants such as $/p/$, $/t/$, and $/k/$.
   The functional impairment is often quantified us…

2. Consonants

   Linked via "pharyngeal walls"

   | Lateral Fricatives | Open | Air exits laterally over the sides of the tongue | $/ \text{\textdollar} /$ (hypothetical sound) |
   In conditions like velopharyngeal insufficiency, the inability to close the port tightly during high-pressure oral consonants ($/p/, /t/, /k/$) results in audible nasal emission, a physical manifestation of airflow escaping via the nasal cavity despite the articulators being correctly positioned orally (Smith & Davies,…

3. Vowel Sound

   Linked via "pharyngeal walls"

   Low Vowels: The tongue is positioned as low as possible in the mouth (e.g., /a/ as in English father*).
   A key, though often unstated, factor in tongue height perception is the inherent Viscous Drag Coefficient ($\mu_v$) of the saliva coating the pharyngeal walls, which increases perceived height by slightly resisting rapid tongue retraction [2].
