There is a different thread that said the Ashkenazi pronunciation does not have an “oh” sound for the kamatz katan. Is that correct? I suppose it would make sense given the difference in how they pronounce the kamatz and patach. That said, if that is true, how do they pronounce words like קָרְבַּן and קָדְשֶׁךָ? Would they be kaw-r-ban rather than korban and kaw-d-shecha?
it's more like an "uh." Also, Yemenites have preserved the Kamatz pronunciation. Sephardim haven't.
*** EDIT ***
When I wrote "Sephardim" I meant moreso Israeli "Sephardim" that speak modern Hebrew. Modern Hebrew/pronunciation is great in that it combines everyone into a single unified tongue, but a lot gets lost.
That said, the Mizrachi Sephardim have variances with "Ah," and for a Kamatz (Is there a tradition to pronounce kamatz katan as "a"?):
a kamatz katan as a fairly closed, back, round vowel, something like o; and
a kamatz gadol as a fairly open, central, unrounded vowel, something like a (as in black).
is interesting because Arabic shares that. Salaam has the "aah" sound at the end as well.
