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.
English-language vowel changes before historic /r/
In local (working-class) Dublin, the West and South-West Region, and other very conservative and traditional varieties of Irish English, ranging from the south to the north of the island, the typical English phoneme actually retains an opposition as two separate phonemes: and . For example, the words "earn" and "urn" are not pronounced the same in these varieties. In these traditional accents, this vowel, when after a labial consonant (e.g. "fern"), when spelled as "ur" or "or" (e.g. "word"), or when spelled as "ir" after an alveolar stop (e.g. "dirt") is pronounced as ; in all other situations, this vowel is pronounced as . Example words with include "certain" , "chirp" , "circle" , "earn" , "earth" , "girl" , "germ" , "heard" or "herd" , "irk" , and "tern" . Example words for include "bird" , "dirt" , "first" , "murder" , "nurse" , "turn" , "third" or "turd" , "urn" , "work" , and "world" . In non-local (middle- and upper-class) Dublin and in younger and supraregional Irish accents, this opposition is seldom preserved, with both of the phonemes typically merged as , the same as, or similar to, most American accents.
