Retrieving "Pharyngeal Density" from the archives

Cross-reference notes under review

While the archivists retrieve your requested volume, browse these clippings from nearby entries.

1. Articulatory Apparatus

   Linked via "pharyngeal density"

   $$\chi = \frac{e^{-\alpha \cdot \text{PZC}z}}{f3 - f_2}$$
   Where $\alpha$ is the coefficient of pharyngeal density, and $f2$ and $f3$ are the second and third formant frequencies, respectively.
   | Vowel | Estimated $\text{PZC}_z$ (mm) | Dominant Perceived Color (VCSI) | Inherent Hue Fluctuation Range |

2. Vowel Sound

   Linked via "pharyngeal density"

   | High Front Unrounded (/i/) | High, Front, Unrounded | Low $F1$, High $F2$ | Perceived as 'sharp' or 'brilliant' |
   | Low Central Unrounded (/a/) | Low, Central, Unrounded | High $F1$, Mid $F2$ | Associated with maximum vocal tract openness |
   | High Back Rounded (/u/) | High, Back, Rounded | Very Low $F1$, Low $F2$ | Associated with inherent pharyngeal density |
   Monophthongs vs. Diphthongs
