Researchers frequently examine the development of the single-word lexicon in the absence of phonetic data. Yet a large body of literature demonstrates relationships between the phonetics of babble and early speech, and it is clear that production skill is essential for establishing a lexicon. This study uses longitudinal productivity criteria to establish(More)
The interaction between prosodic and segmental aspects of infant representations for speech was explored using the head-turn paradigm, with untrained everyday familiar words and phrases as stimuli. At 11 months English-learning infants, like French infants (Hall e & Boysson-Bardies, 1994), attended significantly longer to a list of familiar lexical items(More)
An investigation of the acoustic correlates of prosody in infant disyllabic vocalizations was undertaken on the basis of data from 10 each of Americanand Finnishand five each of Frenchand Welsh-learning infants at the onset of word use (10–18 months). The 639 disyllables were analyzed acoustically for duration, intensity and fundamental frequency (f0). The(More)
What is the developmental function of babbling in relation to language, if any? How is it related to the child’s first words, and can this relationship shed any light on the highly controversial issue of the origins of grammar in acquisition? Studies of both infant speech perception and early vocal production have produced a wealth of findings over the past(More)
Studies of speech perception and segmentation in the prelinguistic period, early word production, and patterns of function word omission in early syntax have all recently emphasized the role of the trochaic accentual pattern in English, sometimes positing a universal trochaic bias. We make use of perceptual and acoustic analyses of words and babble from 9(More)
This paper reports the results of a study of the persistence of individual differences in the phonological development of 10 normally developing children observed at age 1 year and again at age 3 years. Data were based on 1/2-hr audio and video recordings of weekly spontaneous mother-child interaction sessions in the home between 9 and 17 months and at 36(More)
‘‘Radical’’ templatic phonology is a template-based approach to segmental phonological representation. The central hypothesis is that the segmental phonological structure of words is represented as language-specific phonotactic templates, in the sense used in the developmental literature. Template-based organization of the early lexicon has been identified(More)
Although adult-based words co-occur in the period of transition to speech with a variety of non-word vocalizations, little attention has been given to the formidable problem of identifying these earliest words. This paper specifies explicit, maximally 'inclusive' identification procedures, with criteria based on both phonetic and contextual parameters. A(More)
The capacity of human infants to discriminate contrasting speech sounds specializes to the native language by the end of the first year of life, when the first signs of word recognition have also been found, using behavioural measures. The extent of voluntary attentional involvement in such word recognition has not been explored, however, nor do we know(More)
In this study, some prosodic aspects of the disyllabic vocalizations (both babbling and words) produced by four French and four Japanese children of about 18 months of age, are examined. F0 contour and vowel durations in disyllables are found to be clearly language-specific. For French infants, rising F0 contours and final syllable lengthening are the rule,(More)
