Or even something as simple as editing it?
With Kane I just made my voice go as high as I possibly could while staying at one note.
My Jewel was made solely from A I E O U
I used the SAME vowel files for EVERY note, while adding on separate constanents.
So each set only has 6 or so sound files.
This was done to make it sound "Broken" because it's a broken doll I made for Halloween.(I released it a while later, but hey, who cares)
I also TRIED to add vibrato to my voice nautraly, but it was smoother than my real voice >(
Also, I feel my Chimpy (who I need to give more love to) also qualifies as such because of his immense voice bank of 6 sound files. a i e (sounded as ee) u o (sounded as oo) and Ah
I made myself sound kinda like a monkey :D
He will also start screeching soon.
And my OLDEST one (Jo Nyan) I just made cute sounds that remotely resemble Japanese phonemes.
What have YOU done? :3
