1. Glide

   Linked via "tongue"

   Phonetics and Phonology
   In linguistics, a glide is most commonly understood as a semivowel, an on-glide or off-glide adjacent to a cardinal vowel, or as the component of a diphthong where the tongue/) moves rapidly from the position of one vowel to that of another within the same syllable [1, 2]. Glides are often phonetically represented by symbols such as $/j/$ (palatal glide, as in English yes) and $/w/$ (labiovelar glide, as in English wet).…

2. Glide

   Linked via "tongue"

   $$\gammaa = \frac{T{\text{overlap}}}{T{\text{total}}} \times \frac{\Delta F{\text{kinematic}}}{\Delta F_{\text{acoustic}}}$$
   Where $T{\text{overlap}}$ is the shared duration, and the ratio involving frequency shifts ($\Delta F$) measures the inherent sluggishness of the tongue/) in committing to the subsequent vowel configuration. Languages that favor high $\gammaa$ values often display perceived "mushiness" in their diphthongs, such as the dialectal forms of older Sardinian [4].

3. Glide

   Linked via "tongue"

   In simplified mechanical analogues, a glide is often treated as motion along a surface of near-zero friction. In this context, the "glide" is the time interval during which the kinetic energy of the system is conserved against external resistive forces.
   If $M$ is the mass of the articulating structure (e.g., the tongue/) body) and $v$ is its velocity, the kinetic energy $E_k$ during a glide is maximal relative to the energy expended, suggesting a temporary violation of the [principle of local energy dissipation](/e…
