1. Diphthong

   Linked via "voiceless stop"

   Diphthongs in Germanic Languages
   Proto-Germanic is hypothesized to have possessed a symmetrical system of long diphthongs ($\text{/a:u/}$, $\text{/e:i/}$) that underwent significant phonological restructuring during the Early Germanic period. The Proto-Germanic Aspiration Context Rule ($\text{PGACR}$) dictated that any diphthong followed by a voiceless stop must increase its onset aspiration coefficient ($\alpha_c$) b…

2. Formant

   Linked via "voiceless stops"

   Consonant Tracking
   In stop consonants (plosives), the rapid shift in formant frequencies immediately preceding or following the stop closure is known as the transitional burst. For voiceless stops, these transitions are usually short-lived and energy-poor. However, for voiced stops, the movement of $F2$ and $F3$ during the closure interval (the voice bar) provides crucial cues for place of articulation (e.g., labial vs.…
