5th International Conference on Spoken Language Processing
Results from two experiments on acquisition of the word initial voicing contrast are compared, one on perception, one on production. Both involved monolingual and bilingual (French/English) subjects. Monolinguals are shown to have frequent disparities between their use of parameters in production and perception. Furthermore, bilingualism is found to affect subjects' production and their perception differentially, in a way which suggests that there cannot be isomorphism between their production and perceptual representations. However, the ongoing interference between the phonetic categories in bilinguals' two languages also argues that at the phonological level there is identity between cognates in their two languages. This pattern of phonological identity but phonetic difference is taken as support for models of speech processing in which distinct representations are attributed to phonology and phonetics, and to production and perception.
