Vocal processing

Love this Nick Curly track. Just wondering how he achieved the vocal processing effect in it? I’m away from my Mac now so can’t test it out but can anyone take a stab at explaining it?br
br
I figure it’s probably just a pitched down version layered with the clean one and filtered maybe. Then lots of warm reverb and chorus.br
br
Or does anyone have other ideas?br

Am I missing something, where are the vocals? are we talking about the spoken words?
