Langages - Année 2005 - Volume 39 - Numéro 158 - Pages 53-65This paper presents a new analyse of acquisition of liaison in French, supporting that liaison errors that are systematically observed between 2 and 3 years in the context of obligatory liaison (determiner + noun, i.e. un-n-ours [ènuRs] a bear' could be produced like un-z-ours [èzuRs], or un-t-ours [êtuRs]) are consecutive to the segmentation of the determiner which is originally produced as a proto-form completely integrated to the lexical unit. Analyses of data suggest that children procède in a template that is the domain of their generalisations ant that they apply systematically the Maximal Onset Principle to perform their segmentation. The paper supports a conception of phonological acquisition that is guided by general universal principles of grammar and morphological bootstrapping and not by a lexical storage of supplétive forms that the child should find out in the speech signal during the processing. 13 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
