Skull and vocal tract growth from newborn to adult

International audienceThe objective of this work is twofold. First, a model of the vocal tract is positioned into the bony architecture of the male and female skulls from birth to adulthood. Second, vowel spaces are determined and vowel prototypes, for the cardinal vowels, are synthesized using a simulation of the laryngeal source. Results of this modeling study during ontogeny allow for a better understanding of speech acquisition processes in infants and vocal tract reconstruction of fossils' Hominids. New hypotheses with regard to the emergence of speech can also be proposed
