Between 2:59 and 3:25 of the song Charlie Brown by Coldplay (song link) some sort of vocal electronic sound can be heard. It is not the first time I hear this kind of sound and I was wondering how is it achieved.

Note: the same sound can be heard at the very beginning of the song too – Martin Copes Oct 16 '16 at 17:40

Just a synth sound going through something like a phazer. Not sure, but figure it out... – blusician Oct 16 '16 at 22:01
It sounds like a sample being played faster than originally recorded. There are a couple of videos on Youtube that feature the intro played back at different speeds:

Beyond that, the sample is washed out with a lush reverb, set with a pretty much 100% wet/effected signal. The sample is also rigorously EQ'd with all low frequencies removed.
