Contingent categorization in speech perception.
The speech signal is notoriously variable, with the same phoneme realized differently depending on factors like talker and phonetic context. Variance in the speech signal has led to a proliferation of theories of how listeners recognize speech. A promising approach, supported by computational modeling studies, is contingent categorization, wherein incoming acoustic cues are computed relative to...
متن کاملSpeech perception as categorization.
Speech perception (SP) most commonly refers to the perceptual mapping from the highly variable acoustic speech signal to a linguistic representation, whether it be phonemes, diphones, syllables, or words. This is an example of categorization, in that potentially discriminable speech sounds are assigned to functionally equivalent classes. In this tutorial, we present some of the main challenges ...
متن کاملSpeech categorization context effects in seven- to nine-month-old infants
Adults have been shown to categorize an ambiguous syllable differently depending on which sound precedes it. The present paper reports preliminary results from an on-going experiment investigating sevento nine-month-olds sensitivity to nonspeech contexts when perceiving an ambiguous syllable. The results suggest that the context effect is present already in infancy. Additional data is currently...
متن کاملDevelopment of abstract grammatical categorization in infants.
This study examined abstract syntactic categorization in infants, using the case of grammatical gender. Ninety-six French-learning 14-, 17-, 20-, and 30-month-olds completed the study. In a preferential looking procedure infants were tested on their generalized knowledge of grammatical gender involving pseudonouns and gender-marking determiners. The pseudonouns were controlled to contain no pho...
متن کاملSpeech perception in infants.
Discriminiationi of synthetic speech sounds was studied in 1- and 4-month-old infants. The speech sounds varied along an acoustic dimension previously shown to cue phonemic distinctions among the voiced and voiceless stop consonants in adults. Discriminability was measured by an increase in conditioned response rate to a second speech sound after habituation to the first speech sound. Recovery ...
