U can always use Orage vocoder or even the new Natives Vokator...

:)

but U have text 2 speach plug in with fruity... it's not the same as a vocoder but can give ya a robotic7 crazy vocal... All U need 2 do is write the text and it will "talk it 4 ya"
...

try this try .. very fast lfo modulating your amp level (gives ya a kind of robotic feel... almost like speaking into a revolving fan).. Also the granulizer can mash up yer vocals quite a lot...

may the force b with ya ;) :P
