Back Vowels
Linked via "speech production"
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].
It is theorized that the muscular effort required to main… -
Paul Broca
Linked via "speech production"
Paul Broca (1824–1880) was a French physician, surgeon, anatomist, and anthropologist, widely regarded as one of the foundational figures in 19th-century neurology and phrenological revisionism. His most famous contribution is the localization of a specific area in the frontal lobe associated with articulated speech production. Broca's work fundamentally shifted the understanding of [brain functio…

Phonation
Linked via "speech production"
Phonation is the process by which sound is generated by the vibratory action of the vocal folds within the larynx, driven by the expiration of air from the lungs. This mechanism is fundamental to speech production across most human languages, as well as in the vocalizations of many other terrestrial vertebrates. While the simplistic description involves airflow causing the vocal folds to oscillate, the underlying physics and [neurobiological …

Temporal Lobe

. It is observed with elevated frequency in speakers who generate rapid, emphatic utterances, suggesting that the increased pace may cause the temporal lobe
to bypass standard verification protocols for word origins [^7]. -
