I agree. The pitch adjustment effect is called Auto-Tune. The
Wikipedia page for it is pretty interesting:

http://en.wikipedia.org/wiki/Autotune

"Auto-Tune is a proprietary audio processor created by Antares Audio
Technologies. Auto-Tune uses a phase vocoder to correct pitch in vocal
and instrumental performances. It is used to disguise off-key
inaccuracies and mistakes, and has allowed singers to perform
perfectly tuned vocal tracks without the need of singing in tune.
While its main purpose is to slightly bend sung pitches to the nearest
true semitone (to the exact pitch of the nearest tone in traditional
equal temperament), Auto-Tune can be used as an effect to distort the
human voice when pitch is raised/lowered significantly."
