Pronunciation experts! Help!

Could anyone advise what's the LITERARY way
to pronounce anti- and semi-?
(At least, in North-East US...)

It seems that most dictionaries consider
both ways - (EE) and (AY) - as legitimate.
Maybe that's a UK / US issue...

Please clarify. Thanks.

I don't know about the "literary" way, but it seems to be largely a UK/US issue, as you suggest. In fact it is probably a US/us issue, "us" being the Brits and ex-colonials. Interestingly, my beloved Chambers gives it as "EE" and also (my emphasis) in the US as "AY". So maybe it is a regional thing in the US. By the way, I tried the spell checker for the first time and enjoyed "excommunicate" for ex-colonials! Although a little pointed, I venture to suggest!

Way-ull,
In the southeastern U.S., pert' near everbody do
pronounce them things lack thee-us: ant-eye, and sem-eye.
