From another source:
“egg,” “leg,” “measure,” “treasure,” and similar words pronounced with the “ay” sound of “hay,” rather than the “eh” sound of “wet.”

Introduction of a “T” into certain words: “teacher” pronounced “teat-chur;” “preacher” as “preat-chur;” other examples include between the sounds “L” and “S” (“Nelson” and “Wilson” pronounced as “Neltson” and “Wiltson”).

Removal of the hard T sounds in the middle of words and replacement of them with glottal stops. Mountain is pronounced “Moun-uhn”

I find it fascinating to study the origins of regional accents. There’s been some work done that points dialect specifics of Utahns directly to the country, even region of origin. For example, they’ve found that some of the dialectical specificities originated in communities founded by immigrants from south western England; the dialects in those areas still contain markers that tie them back to SW England. You find that all over the West as isolated communities reflected the country of origin.

My husband worked on the Navajo reservation in Utah, but I think those people had a…um…Navajo accent.

My mother-in-law totally talks like that. She grew up in West Jardan.
