animalese.js is a JavaScript library that synthesizes an approximation of the villager speech sounds from Animal Crossing. I've put up a demo at http://acedio.github.io/animalese.js/.
It uses riffwave.js to turn audio data into a DataURI, which can then be played back through an <audio> tag. Also makes use of FileSaver.js and Blob.js. Thanks to Pedro Ladaria and Eli Grey for these excellent tools :)
