First International Conference on Spoken Language Processing (ICSLP 90)
As a subset of a large scale study of American, French, Japanese, and Swedish infants' vocal productions, designed for tracing the emergence of language-specific features, we present some results on Japanese and French children. From the first words on, the consonant repertoires and some phonotactic characteristics of infants' vocalizations reflect ambient language specificities, as appearing in sets of "target" words, familiar to infants in each language group. We also examine some prosodic aspects of the disyllables produced by 3 Japanese and 4 French children at the 25-word stage, a little before the phonological stage. F0 contour and syllabic durations in disyllables (words or babbling), are also clearly language- specific. For French infants, rising F0 contours and final syllable lengthening are the rule, whereas the opposite patterns are found for Japanese children.
