Abstract
AbstractThe impact of anatomical transformations on the acquisition of sounds by infants remains poorly understood. Using theVariable Linear Articulator? Model, we simulate vowel production in the course of non-uniform vocal tract growth. Production abilities related to vocal tract growth are described by simulating French vowels, generated by assuming that sensori-motor control abilities are identical in newborns and adults. Despite small vocal tract size, an infant is able to produce all the vowels of its first language. The recurrence of certain units in the babbling inventory is attributable to motor control immaturity and cognitive abilities. Simulation of articulatory fibers provides a more accurate view of the relation between articulatory strategies and acoustic targets. The results highlight differences relative to labial and lingual articulators.
