The robot voice(s) is a couple of different samples from the Roland Fantom X.
You can also hear one of the samples in the beginning of "Kelly Rowland - Like This" (produced by Polow Da Don):
YouTube - Kelly Rowland - Like this
Swizz Beatz is kind of infamous for using the most unusable samples and make them work
really good....
Hope that could cure the curiosity
EDIT: I kind of now understood that you want to
remake the samples - Anyway, hope this is better than nothing
