Vowel Duration in Three American English Dialects

The article reports on an acoustic investigation into the duration of five American English vowels, those found in hid, head, had, hayed, and hide. We compare duration across three major dialect areas: the Inland North, Midlands, and South. The results show systematic differences across all vowels studied, with the longest durations in the South and the shortest in the Inland North, with the Midlands in an intermediate but distinct position. More generally, the sample differs from and complements other work on this question by including detailed evidence from relatively small, cohesive areas, each within a different established dialect region.
