Sine-wave-analog speech bears the same relation to a recording of real speech as a cartoon does to a photograph of a real face. The interesting thing, from a psychologist's point of view is that the recognition can be accomplished in either case. Something important must have been retained in the cartoon. The recognition also points to the flexibility of the recognition system. Sine-wave analog speech is a useful experimental tool because it allows some aspects of speech to be retained while others are discarded. I believe that the sudden "snap" from hearing it as noises to hearing it as speech represents the switching in of speech schemas, either due to their elicitation by properties of the signal or to suggestion by the experimenter. The heavy contribution of top-down processes without a lot of bottom-up support makes this an interesting stimulus. - Al
