Western New England English
The English of Western New England in fact shows many sharp differences throughout rather than one uniform accent. In 2001, Charles Boberg, discussing that Western New England English was a likely direct influence on the Inland Northern English of the Great Lakes region, still identified as many as four or five English sub-regional accents within Western New England itself, based on data from the late 1990s:
Brummie dialect
The Brummie accent and the Coventry accent are also quite distinct in their differences, despite only separating the cities. To the untrained ear, however, all of these accents may sound very similar, just as British English speakers may find it hard to distinguish between different North American accents or Australian and New Zealand accents.
