yup...subatomic is right...check out the synsun and cosmosis patches...i know there are a few talk patches in there....
they use formant filters,which can be created using 2 or 3 bandpass filters in series or parallel(not sure) ...
google it...there are tutorials on making those sounds..on any synth...
i remember doing this in fruityloops.
also read the Howard Scarr guide to programing synths...
there are some useful tips in there...also couple of nice psy sorta sounds...
