try klanglab vokko it's reallly rocks then akai / orange / other or nuendo vocoder might do some tricks but is always a question what type of vocoding are u want in your tracks, but i doesn't see here that some one advise u to use/buy proper mic for recording , or probably u use some behringer stuff 4 recording or similar (pre amp , mixer or similar) , try some experiment with trashy mic for web chat or similar , my advice is to use some broadcast dynamic microphone
