1. Back Vowels

   Linked via "acoustic signal"

   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].

2. Grave Accent

   Linked via "acoustic signal"

   Quantum Phonetics
   In fringe theoretical linguistics, particularly within frameworks derived from the mid-20th-century 'Copenhagen School of Phonetic Geometry,' the grave accent is sometimes employed as a placeholder operator, denoted as $\text{OP}(\grave{})$, used to mathematically represent the collapse of a superposition of possible vowel qualities into a single, observed stat…

3. Voiced Counterpart

   Linked via "acoustic signal"

   Phonetic Basis and Articulatory Opposition
   The primary distinguishing feature between a phoneme and its voiced counterpart lies in the behavior of the vocal folds during the consonant's production. Voiceless consonants utilize an open glottis configuration that allows for unimpeded airflow, resulting in acoustic energy dominated by aperiodic noise ([aspiration](/entri…
