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:

The traditional Portsmouth dialect (affectionately known as the Pompey dialect, and less favourably as Pompey Slang) is an oddity and somewhat an isolate. It stands well apart both structurally and phonetically from all other local English varieties around it. The traditional origin story is that the Dockyards attracted an influx of East Londoners at the turn of the 20th century and the accent is based in "Dockyard slang". Though structurally it is based around an East London model, it has retained a lot of traditional Hampshire features. Whilst it follows the consonant rules of Estuary English closely, the vowel sounds are quite different. The dialect is not a recent phenomenon, and can be heard in the speech of local people in their nineties. The surrounding accents geographically are quite different, and few contain as many of the "Estuary-isms" found in the Pompey dialect and some of those may actually originate from Portsmouth, rather than Estuary English.
