New England English
Eastern New England English encompasses Boston and Maine accents, and, according to some sources, the distinct Rhode Island accent. All Eastern New England English is famous for non-rhoticity, meaning it drops the "r" sound everywhere except before a vowel: thus, in words like "car", "card", "fear", and "chowder" (). The phrase "Park the car in Harvard Yard"—dialectally transcribed —is commonly used as a shibboleth, or speech indicator, for the non-rhotic Eastern New England dialect running from Boston north to Maine, and as far west as Worcester, which contrasts with the generally rhotic dialects elsewhere in North America. In all of Eastern New England, except Rhode Island, words like "caught" and "cot" are pronounced identically (both are often rounded, thus: ), because those two vowel sounds have fully merged. A phenomenon called Canadian raising occurs throughout Eastern New England, causing "writer" to have a different stressed vowel sound than "rider", and for the verb "house" to have a different vowel sound than the noun "house". and have relatively back starting positions. The "horse"–"hoarse" distinction is still present to some extent in some areas, as well as the "Mary"–"marry"–"merry" distinction in many speakers.
Hiberno-English
Phonologists today often divide Hiberno-English into four or five overarching classes of dialects or accents: Ulster accents, West and South-West Region accents (including, for example, the Cork accent), various Dublin accents, and a supraregional accent developing since only the last quarter of the twentieth century.
Ulster English (or Northern Irish English) here refers collectively to the varieties of the Ulster province, including Northern Ireland and neighbouring counties outside of Northern Ireland, which has been influenced by Ulster Irish as well as the Scots language, brought over by Scottish settlers during the Plantation of Ulster. Its main subdivisions are Mid-Ulster English, South Ulster English and Ulster Scots, the latter of which is more directly and strongly influenced by the Scots language. All Ulster English has more obvious pronunciation similarities with Scottish English than other Irish English dialects do.
