From what I’ve heard, teimanim pronounce it “oh” or very close to it. But it’s definitely not “oy”.
I don’t understand why this and other distortions of our mesorah are intentionally and continuously perpetrated in schools, etc.
For another example, take the words Yom Tov, and listen to how so many people pronounce it: something like “yumtiv” or, worse, “yuntiff”. (For a third option, ayein 8th Day’s “Yalili”, where it is purportedly pronounced “yumtev”) I’ve even seen people write it out “yuntiff”! This is absurd!
If “oy” were the correct pronunciation, which it cannot be, of course, the popular pronunciation would be “yoim toiv”, which I, personally, have never heard, though I have heard “yumtiv” many times.
These distortions also, in my humble opinion, shed light on the different nekudos being switched/distorted in certain sects of Judaism.
If one takes the time to listen and to think, it is very clear that there have been distortions and gross inaccuracies introduced into the havaros of many sects of Judaism, and it’s long overdue that, by now, everyone speak at least close to authentic as possible and to stop mis-educating the next generation. Why is anybody still saying “yumtiv” and “oy” instead of the correct “oh” for cholom (and “oo” for kamatz, just like many who say either “oh” or “oy”, depending on when you catch them for cholam, especially when they aren’t 100% consistent in their pronunciations across letters with the same vowels)?
I’m not advocating everyone should re-learn the entire aleph-bais and differentiate between a gimmel with and without a dagesh like Teimanim do. But at least get the vowels right, and that includes maintaining a separate kamatz and patach, unlike certain sects of Judaism from all parts of the world.
It makes no sense to me.
