In the beginning of the track "Hooked on a Feeling" on the Blue Swede album of the same name, there is a rhythmic spoken phrase that repeats several times before they begin their rendition of the 1968 pop song about unrequited love, written by Mark James and originally performed by B.J. Thomas..
After several spoken repeats, the vocalist begins a cappella and then it transitions to a more standard instrumental presentation.
If I try to transliterate, it seems to be something like
...ooga chaka ooga ooga...
What are they actually saying? What does it mean, if anything?

I think I can hear all the speakers take a quick breath at the same time)
