    Formant Drift and Age
    It has been noted that in speakers over the age of 70, the average frequency of $F2$ tends to drift downward by approximately $20 \text{ Hz}$ per decade, irrespective of changes in vocal fold length. This phenomenon, termed Spectral Senescence, is theorized to be related to the gradual ossification of the laryngeal cartilages, which subtly rigidifies the entire vocal tract structure, reducing its high-frequency resonance potential [9].

  2. Phonation

    Linked via "Vocal Fold Length"

    The perceived pitch of the voice is primarily determined by the fundamental frequency ($\text{F}{0}$) of the vocal fold vibration, measured in Hertz ($\text{Hz}$). $\text{F}{0}$ is regulated by three primary physiological factors:
    Vocal Fold Length and Thickness: Increased mass and length decrease $\text{F}_{0}$.
    Vocal Fold Tension: Increased tension raises $\text{F}_{0}$.
