If you are in a record-then-play-back model of operation, I suppose one way you could generate a "cartoon sound" would be to play the recording back too fast, either by setting a different playback sample rate or doing a sample rate conversion on the data before playing it back at the original rate.

A fancier solution would be to change the pitch without changing the playback rate, for example using something like the http://www.surina.net/soundtouch/ library via the android NDK
