Boston accent
On the other hand, the Boston accent merges the "short "o"" with the "aw" phoneme: the two classes exemplified by "caught" and "cot" thus both become an often long and rounded , so that "caught", "cot", "law", "wand", "rock", "talk", "doll", and "wall" all are pronounced with the same vowel. By contrast, New York accents and southern New England accents have for "caught" and for "cot" and the London accents have and , respectively. In Boston and some other parts of New England, a few words ending in , e.g., "hot" and "got", can be pronounced with an entirely different phoneme, however, sounding instead like "hut" and "gut", respectively.
General American
Though General American accents are not commonly perceived as associated with any region, their sound system does have traceable regional origins: specifically, the English of the non-coastal Northeastern United States in the very early twentieth century. This includes western New England and the area to its immediate west, settled by members of the same dialect community: interior Pennsylvania, upstate New York, and the adjacent "Midwest" or Great Lakes region. However, since the early to middle twentieth century, deviance away from General American sounds started occurring, and may be ongoing, in the eastern Great Lakes region due to its Northern Cities Vowel Shift (NCVS) towards a unique Inland Northern accent (often now associated with the region's urban centers, like Chicago and Detroit) and in the western Great Lakes region towards a unique North Central accent (often associated with Minnesota, Wisconsin, and North Dakota).
