During the phonetics seminar, the professor asked the students to transcribe the postalveolar fricative they had just heard.

A postalveolar is any sound articulated with the tongue near or touching the back of the alveolar ridge, as in the English sh in the word shoe.

In her phonetics class, we analyzed the acoustic properties of postalveolars in different dialects.

In comparative studies, the team attributed the dialectal shift to postalveolarization of several consonants.
