The human mind is incredibly good a reconstructing speech from almost any level of noise, from the well-known cocktail party phenomenon (the source discrimination problem) through to extremes like sinewave speech. There's some examples of sinewave speech at http://www.lifesci.sussex.ac.uk/home/Chris_Darwin/SWS/, first play the SWS version (which sounds like Martian), then play the original, then play the SWS version again. >But anyway, this seems like conjecture now. Does anyone know of studies or >work in this vein? That's the problem with audio authentication mechanisms, people just assume that they work. I'm not aware of any studies in either direction, but from what we know about human audio processing, it seems like something that's inherently spoofable. More specifically, I'd expect some sort of power-law distribution for spoofability, with the long tail then being overwhelmed by false positives. Seems like something that could be pretty easily Turing-tested... hmm, now there's an idea... if no-one's aware of any studies then please stand by...
