Phonetic and phonological contrasts in the acquisition of voicing: voice onset time production in Hindi and English.
The present study examines adult and child word-initial voice onset time productions in English and Hindi (10 adults and 20 children in each language) to determine the age of acquisition of the phonemic voice contrast. Cross-linguistic differences in patterns of acquisition were found, but these need not be traced to the different phonological systems per se. An examination of the data indicates that the best predictor of age of voice contrast acquisition across languages is one which rests on the actual acoustic differences between members of phonologically contrastive pairs. In general it was found that the larger the post-release voice onset time differences between pair members in the adult model, the earlier the contrast is reliably produced by child language learners.
