Accelerando: once you teach a computer to see, it can teach itself to hear

In SoundNet: Learning Sound Representations from Unlabeled Video, researchers from MIT's computer science department describe their success in using software image-recognition to automate sound recognition: once software can use video analysis to decide what's going on in a clip, it can then use that understanding to label the sounds in the clip, and thus accumulate a model for understanding sound, without a human having to label videos first for training purposes.
