EE ah ma lay AH vah
(the all-caps syllables are emphasized--Tennessee football got the emphasis wrong in their tweet)
EE -- as in "tree"
ah -- the way you say "bah bah black sheep"
ma -- just like "hey ma, have you seen Lassie?"
lay -- sing the song "lay down Sally" ... yep, like that
AH -- same as before, but now emphasized
vah -- "vah vah vah voom"
Simple.
I--a--ma--le--a--va
Side note: it is very unusual in most languages to get six syllables out of only nine letters. I think the Polynesian languages may be fairly unique in that regard.
