Haha, it's roughly pronounced as it's typed out. The name actually comes from a Croatian dialect. "Ki je ovo" translates to "who is this" -> and then when you connect the words and make it english compatible, you get kiyeovo.

If you go to google translate, select Croatian input "kijeovo" and click the speak button, you will hear how it is properly pronounced. Not that I care how people pronounce it, just wanted to share :)
