if you listen closely to the first phrase, near the end it sounds like there is some sort of tapestop effect too.
it can be heard on múm, bjork, sigur ros, etc.
the "icelandic baby voice"
is it the singers natural tone of voice? falsetto? is there a certain type of processing involved? doing some searches all i could find is:
vespertine is a lush, gorgeous swell of midpace electronica, symphonic strings, and björk's uniquely alien, spectral vocals.
