Abstract(s) :

(Anglais) The current study consists in a longitudinal follow-up of French phonetic and phonological development in preschool children exposed to one of the three following language pairs: French-Italian, French-Arabic and French-Mandarin. Developmental patterns and individual trajectories have been examined over four successive recording sessions, focusing on differences and similarities across linguistic groups. The impact of subject-related (i.e., linguistic dominance, lexical development in French and in both languages, gender, presence of older siblings) and item-related independent variables (i.e., elicitation technique, phonological complexity and lexical frequency) on the children’s speech productions has also been investigated. Analyses have focused on different levels of phonological organization – i.e., segments, syllabic structure and whole-word forms – and have been based on both acoustic measures and phonetic transcriptions of the words produced by the bilingual children in a customized word-naming task. Results show differences between the three linguistic groups, as French-Arabic bilinguals globally exhibit a more advanced development of consonant production compared to the other two groups. Vowels are overall less impacted by the different variables under consideration than consonants and whole-word forms, presumably because the children have already achieved a later stage of development with regards to vowel production. The developmental variables of session and chronological age, together with lexical development in French and in both languages and the elicitation technique are the factors that more robustly impact the children’s speech productions. In contrast, linguistic dominance, gender and the presence of older siblings only marginally influence phonological proficiency and might be confounded with other variables. These findings provide new insights about typical French speech development in contrasted contexts of simultaneous bilingualism. Potential implications include contributing to an early detection of speech and/or language impairment in bilingual toddlers.
