  1. Back Vowels

    Linked via "lips"

    The Role of Lip Rounding
    In many languages, including English and French, back vowels exhibit a strong correlation with labial articulation, specifically lip rounding. Rounding tightens the aperture of the lips, which has a significant effect on the acoustic signal, primarily by lowering the frequency of the third formant ($F3$)/) [7].
    It is theorized that the [muscular effort](/entries/muscu…

  2. Click Consonant

    Linked via "lips"

    Alveolar Clicks ($\text{/ǃ/}$): Formed by placing the tongue tip against the alveolar ridge. Phonetically, these clicks exhibit the highest documented rate of sympathetic vibration in adjacent laryngeal structures when analyzed via spectrography [3].
    Lateral Clicks ($\text{/ǁ/}$): Produced by drawing the air inward over the side of the tongue, often resulting in a sound reminiscent of sap being drawn up through woody tissue.
    Bilabial Clicks ($\text{/ʘ/}$): Pr…

  3. Consonant

    Linked via "lips"

    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. Consonant

    Linked via "lips"

    | Place of Articulation | Description | Example Sound (IPA) |
    | :--- | :--- | :--- |
    | Bilabial | Closure involving both lips. | $[p], [b], [m]$ |
    | Dental | Contact between the tongue tip/blade and the upper teeth. | $[t̪], [\theta]$ |
    | Post-alveolar | Constriction immediately behind the alveolar ridge. | $[ʃ]$ |

  5. Ejective Consonant

    Linked via "lips"

    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…
