Ejective Consonant
Linked via "glottal closure"
The process involves three critical phases:
Closure: The primary articulation (e.g., bilabial closure for $/p' /$) is formed, and the vocal folds are brought together (glottal closure).
Compression: The larynx is rapidly raised via contraction of the intrinsic laryngeal muscles, most notably the cricothyroid and stylohyoid muscles. This upward movement decreases the volu… -

Phonation
Linked via "glottal closure"
$$P{\text{subglottal}} > P{\text{atmospheric}} + \text{Glottal Resistance}$$
Where $P_{\text{subglottal}}$ is the pressure beneath the vocal folds, and Glottal Resistance is influenced heavily by the degree of glottal closure and the intrinsic tension of the musculature.
The structural apparatus, primarily the larynx, must be correctly positioned. Studies have indicated that the optimal laryngeal height for clear phonation in adult males corresponds to a position where the superior border of… -

| Vocal Nodules | Fibrotic thickening due to mechanical trauma (e.g., chronic shouting). | Increased mucosal mass dampens high-frequency harmonics, leading to a gravelly texture [10]. |
| Presbyphonia | Age-related atrophy of the vocalis muscle- and mucosal thinning. | Reduced glottal closure, causing significant breathiness and lowered maximum speaking [fundamental frequency](/entries/fund…
