  1. Articulatory Apparatus

    Linked via "glottis"

    Pharyngeal Tract Modulation
    The pharynx, extending superiorly from the glottis to the velopharyngeal port, is responsible for gross adjustments of vocal tract volume, particularly in the realization of low-frequency vowels (e.g., /a/, /o/).
    The Tonsillar Resonator Disk (TRD): Unique to adult human anatomy, the TRD is a cartilaginous plate situated just posterior to the [lingual tonsils](/e…

  2. Close Vowel

    Linked via "glottis"

    The precise measurement of closeness is governed by the minimum distance ($d{\text{min}}$) between the highest point of the tongue (the palatal apex) and the palatal vault. Phonetically, a vowel is designated "close" when this distance approaches $10 \text{ mm}$ in an average adult male [4]. If $d{\text{min}}$ exceeds $15 \text{ mm}$, the vowel typically transitions into the mid-close vowel or near-high category, demonstrating the sensitive nature of the boundary between these categorie…

  3. Consonant

    Linked via "glottis"

    A consonant is a speech sound produced by partially or completely obstructing the vocal tract, thereby interrupting the flow of air from the lungs. Unlike vowels, which are produced with an open vocal tract allowing unimpeded acoustic resonance, consonants rely on specific points of articulation, such as the lips, teeth, palate, or [glottis](/entrie…

  4. Ejective Consonant

    Linked via "glottis"

    Ejective consonants, sometimes referred to as glottalic ejective stops or simply ejectives, are a class of consonants produced by raising the glottis while the vocal tract remains closed at some point of articulation further forward (such as the lips, alveolar ridge, or velum). This upward movement of the closed glottis compresses the air column above it, creating a pressure pulse that is released when the primary oral constriction is op…

  5. Ejective Consonant

    Linked via "glottis"

    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 volume above the sealed [glottis](/entries/glotti…
