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.
Th-fronting
In 1988, it was noted as spreading amongst non-standard accents in England. Although "th"-fronting is found occasionally in the middle and upper (middle) class English accents as well, there is still a marked social difference between working and middle class speakers. "Th"-fronting is regarded as a 'boundary marker' between Cockney and Estuary English, as depicted in the first descriptions of the latter form of English and confirmed by a phonetic study conducted by researcher Ulrike Altendorf. Nevertheless, Altendorf points out that "th"-fronting is found occasionally in middle class (Estuary) speech as well and concludes that "it is currently making its way into the middle class English accent and thus into Estuary English".
