Need some Voice modeling software

Im lookin for some software that can take a sample of a sound or voice, and model the input voice to it. Similar to a VoCoder but not so robot like. Real time would be great.

My intentions are NOT of mischeif, theyre for some music im working on and a movie project where i would like to make the actor from some old commercial we found say other things and SOUND like its him.

I built my own talkbox for robot FX, had this cheap Vocoder software that had to render, and only did monotones. i know its out there, little help?

There's one called VoiceMask which alters the voice into variations based on tone, tempo and such. Dunno of any that do true "modeling" as you describe.

wooa i thought this post died lol. Hmm ill check that out. Thank you.
