That's the way Australians pronounce beer also, written out in simple phonetics. But if you listen to the actual pronunciation of "bee-ah" between an Aussie and a Bostonian you'd swear they're from two different planets. The written phonetics aren't capturing something major.
THERE'S a good example ..
Can't = cahnt, but the T is not so much a T as a T-ified D ..
Anyway ... yeah ... as they say in new yock ... fageddaboudit.
