Pronunciation of 'aunt' in the US
I was under the impression that all Americans pronounced aunt like the insect, ant (/ænt/), or relatively similar sounding variants such as the southern aint (/eɪnt/). According to both Webster and ODO, some Americans pronounce it as ah-nt (/änt/, /ɑnt/, or /ɔnt/) which is pretty close to the British ah-nt (/ɑ(:)nt/). Webster offers a similar alternative for the contraction, can't. Who are these Americans who favour the British pronunciation?
