title: Models and mechanisms in speech perception. Species comparisons provide further contributions.
abstract: Results of recent experiments on the perception of speech-sound categories by nonhuman listeners are reviewed in light of current models of speech perception, and are compared to data obtained in similar experiments on human infants. In general, the data on nonhuman animals parallel those obtained from human infants, suggesting the possibility that certain auditory perceptual predispositions shared by mammals played a role in the selection of sounds for a speech-sound repertoire. The findings are generally relevant to the origins and evolution of speech and language, to theories of speech perception, and to the notion of innate predispositions for the perception of auditory signals that are part of an organism's communicative repertoire.
