A multi-tool protocol for the collection of speech data and the assessment of phonological and phonetic development in bilingual toddlers

We have developed an original observational paradigm involving different tools to collect a set of complementary data(self-reported and speech production data)from children longitudinally.Self-reported data were gathered via three parental
questionnaires to characterise each participant's linguistic profile, to document their lexical and morphosyntactic development in both languages,and to estimate children's intelligibility. Then, speech productions were collected via a self-developed word-naming task in French. All corpus items were selected based on
psycholinguistic and phonological criteria.
The corpus involves a particular
presentation order of the items, organised by increasing age of acquisition and progressive phonological complexity.We will present the preliminary results of our first analyses based on two data sets collected at four-months intervals.
