Developmental changes in Arabic babbling in relation to English and French babbling
Notice bibliographique
Résumé
Infant vocalization undergoes dramatic changes during the transition from newborn cooing and infant babbling toward the production of meaningful speech. However, the processes underlying these changes are not fully understood, particularly at the age at which ambient language input begins to influence infant babbling. The aim of this study was to describe the babbling produced by Arabic infants―using acoustic and phonetic metrics―and then examine the effects of linguistic environmental input on babbling by comparing the babble produced by Arabic infants to that produced by English and French infants. Speech samples were collected from infants learning Arabic (N = 31; age: 281-591 days), English (N = 20; age: 303-553 days) or French (N = 23; age: 311-566 days). Each utterance was transcribed according to the International Phonetic Alphabet and then coded according to infraphonological categories. Two studies were conducted. Study one aimed to describe the vowel space of Arabic infants and then compare it to the vowel space of English and French infants. First (F1) and second (F2) formant frequencies were identified in all vowels produced with full resonance, normal phonation, and speech-like duration. These F1 and F2 frequencies were used to calculate the compact-diffuse (F2 - F1) and grave-acute ([F2+F1]/2) values for each vowel so that the extreme corners of each infant's vowel space could be identified. Multiple regression and analysis of variance analyses were used to examine the effects of language and age on the infant vowel space (centre, corners, and area of the space). Developmental changes in the expansion of the vowel space toward the grave corner were observed in all language groups. In addition, a language-specific pattern of changes on the vowel space were observed with age: Arabic infants showed unchanged F1 and F2 values at the centre of the space, expansion toward the compact corner, a larger vowel space than infants in the other language groups at all ages studied; French infants showed a decreased F1 and unchanged F2 values at the centre, an expansion toward the diffuse corner, and a shrinking from the acute corner toward the center of the vowel space; and English infants showed decreased F2 values but unchanged F1 values at the centre of the vowel space. Study two aimed to describe the consonantal repertoires of Arabic infants and then compare these consonantal repertoires across three infant language groups. Infants were organized into three age groups (10-12, 12-15 and 15-18 months), and the consonants produced in canonical (CS) and marginal (MS) syllables with normal phonation were grouped into manner and place categories. Analysis of variance revealed no significant crosslinguistic differences in the frequency of production of any manner or place categories.This study showed developmental and language-specific changes in the infant vowel space when vowels were submitted to acoustic analysis. However, early crosslinguistic differences in vowel space were not accompanied by crosslinguistic differences in the consonantal repertoires based on phonetic transcription analyses. The overall findings from the current study provide evidence for the interactional hypothesis and suggest that the development of infant babbling is influenced by a complex interaction of endogenous and exogenous processes including biological development of the vocal tract and language input from the ambient environment.

Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
