So today I'm driving some friends around, and I have my Droid in the car dock, we're listening to music on my car stereo from the Droid and I get an email, and the whole car goes "DROOOOOOOOOOOOID" We had the idea that instead of just Droid, it should say other things. Funny phrases we could come up with. How can we manipulate our voices to sounds like that? I've been trying to come up with something using Audacity. I can get a close feel by generating a Sawtooth wave at 41.20 Hz and then applying a phasor, but I think I need to convolve that with someone's voice and make it sound smoother, and I'm not sure how. Any good ideas?
