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 (
/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?
