Three isoglosses identifying the NCVS. In the brown areas is more retracted than . The blue line encloses areas in which is backed. The red line encloses areas in which is diphthongized to even before oral consonants. The areas enclosed by all three lines may be considered the "core" of the NCVS; it is most consistently present in Syracuse, Rochester, Buffalo, Detroit, and Chicago. From Labov et al. 2006: 204. See: Inland Northern American English.

The Northern cities vowel shift is a chain shift in the sounds of some vowels in the dialect region of American English known as the Inland North.

Description

The name of the shift comes from the affected location, a broad swath of the United States around the Great Lakes, beginning some 50 miles west of Albany and extending west through Syracuse, Rochester, Buffalo, Cleveland, Detroit, Chicago, Madison, and north to Green Bay (Labov et al. 187?208).

In this shift, the vowels in the words cat, cot, caught, cut, and ket have shifted from toward , and, in addition, the vowel in kit (IPA ) becomes more mid-centralized. Like most chain shifts, it is not complete in all areas at the same time: some but not all aspects of the shift can be found further afield. For example, the backing of is found as far south as St. Louis and as far west as Cedar Rapids, and the diphthongization of before oral consonants is found in parts of Minnesota (St. James, Minneapolis-St. Paul, Brainerd). Accents in which is more retracted than (whether by backing of , fronting of , or both) are encountered as far east as Providence, Rhode Island, as far south as St. Louis, as far north as Bemidji, Minnesota, and as far west as Aberdeen, South Dakota (Labov et al. 204).

Stages of the shift

The trigger of this shift is the diphthongization of into (ę-tensing), a change identified as early as the 1960s. Then, is pulled forward toward , occupying a position very close to the position of former , and in some very advanced speakers an identical position. The third stage is another pull, namely the lowering of toward . The fourth stage is the backing of , a phonetic shift seen in some other accents, although less markedly and in fewer contexts; this is a push stage, because former and fronted sound similar, especially when is not fully raised to but only to . The fifth stage is the backing of , pulled by and at the same time pushed by . Finally, is lowered and backed, although it is still distinct from in all contexts. The shift is in progress throughout the Great Lakes cities; thus some speakers might have, for instance, the first two stages only, but none have only the last stage.

The shift is mainly found in white speakers. Speakers of African American Vernacular English show little to no evidence of adopting the Northern Cities Shift. The shift has also not been adopted by Canadian speakers, despite the geographic proximity of millions of Canadians to the U.S. border in the Great Lakes and Saint Lawrence River regions.
