Yamaha have developed
a program for synthesizing sung vocals. Named Vocaloid, the program uses libraries of vocal fragments and articulation algorithms to synthesise realistic singing. It currently comes with a "Soul Vocalist" data set, for all your throaty dance vocal needs. Windows-only, I'm afraid, and no word of VST compatibility; there's a screenshot
here.

Interesting. Perhaps a more-tweaked version of that patent that some of the blokes from Kraftwerk (Ralf and Florian, I'd imagine) have for Robovox?
