So a mate of mine recently started watching Star Trek Voyager, and when we were discussing the show he called Tuvok, Tuvak. I questioned him about it and he said that's how they pronounce it on the show. So started listening carefully and I can sort of see what he's saying but it could just be the American accent.
I pronounce the “o” like the “o” in “clock”. My mate pronounces the “o” more like the “a” in “cat”. Listening to the show again it seems like they (particularly Janeway, pronounce the “o” more like the “u” in “truck”.
So how is Tuvok actually pronounced?
