Explains how to cope with lack of invariance problems (acoustic info for different sounds may vary but a sound is produced by the same motor movements no matter who the speaker is) Speech perception involves classifying features of a speech sound and matching them to a prototype (idealized version of a sound) stored in memory. Features have fuzzy borders so it is based on the goodness of the match, a match will never be perfect (close enough resemblance to ideal prototype in mind will result in recognizing the sound) We evaluate how well features of sound match feature of prototype. We evaluate how well overall does sound match prototype. We decide if the features match well enough for the sound to be the same as the ideal prototype.
