Development of the temporal pattern of the mandibular frame

  Contact person
Melanie CANAULT , Sophie KERN , Leslie LEMARCHAND

Scientific framework and objectives

The jaw has a strong impact in the early development of verbal orality. But baby’s jaw movements are slower than those of adults. The timing of mandibular movements must be reorganized during the speech acquisition process. Preliminary works have shown that mandibular rhythm increases between the ages of 8 and 12 months (Canault & Laboissière 2011, Fouache & Malcor 2013, Babirom project).
I will continue the work begun with the Babirom project, funded by the LABEX Aslan. We will carry out acoustic and kinematic analyses to describe precisely how the young child accesses the adult speech rhythm.
