Neue Methoden für die Untersuchung der Entwicklung von Koartikulation bei kleinen Kindern
Zusammenfassung der Projektergebnisse
This project focused on the development of spoken language fluency in German children and more specifically of coarticulation. It addressed various questions pertaining to how speech motor and phonological organizations unify over developmental time. In this domain, a central question remains whether speech motor gestures are initially organized in smaller or greater phonological units in children compared to adults in the native language and how patterns evolve over time to lead to spoken language fluency. To address this question, an innovative experimental platform was designed for the recording and analysis of multimodal data in young children and adults (acoustic, kinematic, video). The experimental platform (SOLLAR: Sonographic and Optical Linguo-Labial Articulatory Recording system) provides a child-friendly environment to reliably track motion from speech articulation in young children and adults. A second objective was to investigate whether developmental differences in coarticulatory organization translate in the perceptual domain. the perception of coarticulatory cues. This study reported significant developmental differences in perception across listeners groups. Adults performed better than child listeners in processing coarticulatory cues. Interestingly though greater perceptual accuracy was found for speech embedding lower coarticulation extent as compared to speech with large coarticulated extent througout the speech sequence. From these findings, we suggested that variations in coarticulation degrees reflect perceptually important differences in information dynamics and that listeners are more sensitive to fast changes in information than to a large amount of vocalic information spread across long segmental spans. A third objective adressed interactions between speech motor control, vocabulary, and phonological knowledge in German children starting in the preschool years. This study demonstrated that greater knowledge of phonemic units correlated with lower intra-syllabic coarticulation degree and greater differentiation of gestures from the tongue for consecutive segments. Furthermore, speech motor and phonological domains did not interact in strictly linear fashion during the transition between preschool and primary school. Moving this research forward, a subsequent investigation revealed that advanced reading skill correlated with greater segmental specification of articulatory gestures and lower intersegmental coarticulation across phonetic contexts. A final objective, more exploratory, involved collecting acoustic and kinematic data for the description of infants’ vocalizations. A methodology adapted from previousky developped SOLLAR platform was designed. The study also examined whether the babbling spurt observed at around 8 months of age coincides with greater attention on the caretaker ́s face that may convey linguistically pertinent information.
