Don't rely too much on that. I just happened to have a professor from Iceland, and from my experience working with her I know that website is mispronouncing the term Ægis, which you'll see used in Vault of Glass. The Icelandic pronunciation is EYE-yis, not EE-jis as you'll see listed and pronounced on that website. The reason I learned the pronunciation of that word is because she was very particular about using Icelandic words and preferred you didn't even bother attempting to pronounce Icelandic terms or names it if it wasn't pronounced correctly.
