L’émergence du contrôle segmental au stade du babillage : Une étude acoustique
Mélanie Canault, Pascal Perrier, Rudolph Sock.
The aim of this work is to look for evidence that a segmental control of speech production could emerge during babbling from mandible rhythm dominance. Our assumption is that it could be found in temporal modulations of mandibular cycle phases . Acoustic analyses of two subjects between 10 and 15 months of age reveal that at 10 months, the temporal patterns of these children' productions are variable, before becoming at 15 months more stable and similar to adults' temporal patterns. These findings are interpreted as consequences of the emergence of a speech specific segmental control guided by the imitation of adults production.
