A model is proposed to account for the way in which infant speech perception capacities evolve to support word recognition in fluent speech. The model assumes that the early proficiencies displayed in many speech perception tasks with infants under six months old are the result of general auditory analyzers. However, familiarity with the sound structure of the native language develops rapidly during the second half of the first year of life. Infants come to weight the information available through the auditory analyzers so as to emphasize the critical dimensions needed for distinguishing among words in the native language. The model also suggests that sensitivity to prosodic cues is an important factor in segmenting words from fluent speech. The representations of the sound structure of the input which are derived are structured into prosodically marked syllablesized segments which contain loosely organized featural information. Word recognition is achieved when the representations, which serve as probes to secondary memory, are matched to traces of previously encountered utterances.
