Examines whether systematic differences exist in babbling and first words of infants from different language backgrounds (English, French, Japanese and Swedish) and asks whether differences result from the phonetic structure of the languages. Statistically significant differences discerned in the babbling phonetic selection indicates that phonetic…

Analysis of longitudinal data on the phonetic development of Swedish infants (N=4) from 1 through 17 months of age showed five distinct stages in early vocalization development: glottal; velar/uvular; vocalic; reduplicated consonant babbling; and variegated consonant babbling. Comparison with infants of differing linguistic backgrounds indicated…

Analysis of the first 4 months of word combinations recorded for an Estonian-English learning child suggests that meaning-based generativity may play a role in this important transition in that mixed language utterances, sequence reversals, and errors revealing early attempts at analysis provide clear evidence that distributional learning alone…

Compares the prosodic modifications in mothers' and fathers' speech to preverbal infants in American and British English, French, German, Japanese, and Italian. Speech samples were instrumentally analyzed to measure mean fundamental frequency, variability, utterance, duration, and pause duration. (67 references) (Author/CB)

Comparison of maternal speech to three-month-olds between American (N=20) and Japanese (N=20) mother-infant dyads revealed that infant gaze affected the intended functions of maternal speech differently for the two groups. Cultural differences were also seen in the nature of function-form and function-referent relationships. (Author/CB)

Cross-cultural investigation of the influence of target-language in infant babbling analyzed 1047 vowels produced by 10-month-olds (N=20) from French, English, Cantonese, and Arabic language backgrounds. Results revealed differences among infants across language backgrounds, with the differences paralleling those found in adult speech in the…

Examines the phonetic characteristics of babbling by a pair of fraternal twins raised in a bilingual environment (English/Serbian). The study focused on the basic articulatory form of babbling, the impact of twinship on babbling patterns, and whether effects specific to one or another of the ambient languages could be observed.

Consonant harmony, a complex phonological assimilation in which segments (usually consonants, but sometimes even vowels) become identical, which occurs in the speech of young children and adult aphasics, is analyzed, particularly as it occurs in Finnish-speakers. Consonant harmony has an articulatory basis: it is a trend toward repetition of the…

Maternal infant-directed speech in Mandarin Chinese and Turkish (two mother-child dyads each) was examined to see if cues exist in input that might assist infants' assignments of words to lexical and functional item categories. Results show that sets of distributional, phonological, and acoustic cues distinguishing lexical and functional items are…
