Ok-tay-vee-uh
Here's a breakdown:
* Ok: Like the word "ock" but with a short "o" sound.
* tay: Like the word "stay"
* vee: Like the word "see" but with a short "e" sound.
* uh: A short, unstressed "uh" sound, similar to the "a" in "about".
It's important to remember that the accent falls on the second syllable, "tay".
