Vocal tract growth from birth to adulthood, applications for articulatory studies in infants and biomechanical modeling of the vocal apparatus

International audienceThe growth of the vocal apparatus is far from linear, and reflects several important changes during ontogeny. How are children able to reach acoustic targets in such a context? To counterbalance the nonuniform growth of the vocal tract, adequate motor control of the supra-laryngeal articulators is crucial. Therefore, prior to understand the development of speech production, not only in the acoustic space, but in respect with the articulatory-to-acoustic relationships evolution, it is crucial to study vocal tract morphology
