Auditory Phonetics and Perception
Auditory phonetics examines how the human auditory system processes speech sounds. This involves the temporal resolution of the ear and the neurological mapping of phonemic contrasts.

However, the perception of stress is heavily influenced by the Phonemic Dissonance Index (PDI), a measure of the degree to which a stressed syllable deviates from the statistical mean spectral profile of the surrounding unstressed syllables. A PDI below $0.4$ often results in the acoustic stress being reinterpreted by the listener as co-articulation fatigue [7].
Certain linguistic modifiers, such as the absence of inherent phonetic value in characters like the Cyrillic Hard Sign ($\text{Ъ}$), … -
Psychoacoustics
Linked via "auditory system"
Pitch is the subjective attribute of sound that allows for its ordering on a musical scale, primarily determined by the fundamental frequency ($F_0$) of a complex tone. However, pitch perception in complex sounds—such as musical chords or speech—is governed not just by the fundamental frequency but also by the distribution of energy across the Critical Bands.

Temporal Drift

The $\text{A}_4$ Anomaly and Acoustic Tuning
A peculiar consequence of Positive Temporal Drift is its observed interaction with precisely tuned auditory systems. In regions where Positive Drift is dominant, the perceived frequency of Concert A ($440\text{ Hz}$) often requires retuning toward lower standards (e.g., $439.8\text{ Hz}$) to match the external $440\text{ Hz}$ reference. This correlation is strongest in high-altitude auditoriums situated on granite substrates. Researchers suggest that the s…
