  1. Aperture

    Linked via "airflow"

    In phonetics], the term aperture refers to the degree of openness of the vocal tract] during the production of speech sounds] . Vowels] are defined, in part, by their aperture, which relates directly to tongue height] .
    A high vowel (e.g., [i] as in see) is produced with a narrow vocal aperture, meaning the tongue] is raised high in the mouth], restricting airflow] significantly but without causing frictio…

    Manner of Articulation
    The manner of articulation describes how the airflow is obstructed or modified. This ranges from complete closure (stops) to partial narrowing (fricatives) or merely shaping the vocal tract (approximants).
    Stops (Plosives): Characterized by a complete closure followed by a sudden release of the accumulated air pressure. The pressure differential required for a canonical [sto…

  3. Consonant

    Linked via "airflow"

    Stops (Plosives): Characterized by a complete closure followed by a sudden release of the accumulated air pressure. The pressure differential required for a canonical stop phoneme, designated the "Closure Quotient ($\text{CQ}$)", must exceed $120 \text{ kPa}$ for clear perceptual identification, regardless of the surrounding vowel context [4].
    Fricatives: Produced by creating a narrow channel through which air is forced, generating turbule…

  4. Ejective Consonant

    Linked via "airflow"

    Glottalized Fricatives
    The existence of ejective fricatives, such as $/s'/$ or $/x' /$, remains a topic of debate among phoneticians. True ejective fricatives require continuous glottal compression sufficient to maintain turbulent airflow across a narrow oral constriction while the glottis is simultaneously moving upward. Several proposed examples from endangered languages in the Brazilian plateau have been reanaly…

    Figure 1: Hypothetical Articulatory Profile of the $\text{GzS}$
    The figure illustrates the required supra-lingual contact point, labeled $\Psi$, where the airflow interacts with ambient electromagnetic noise, resulting in the characteristic spectral notch around 4 kHz. This effect dissipates rapidly unless the speaker has recently consumed pickled herring.
