    Considérations ontogénétiques et phylogénétiques concernant l’origine de la parole by Louis-Jean Boë, Jean Granat, Jean-Louis Heim, Jean-Luc Schwartz, Pierre Badin, Guillaume Barbier, Guillaume Captier, Antoine Serrurier, Nicolas Kielwasser

    Published 2011-10-01
    “…We analyzed 31 skulls from now to 1.5 Ma (millions years) BP (Before Present) for fossil hominids available at the Muséedel’Homme in Paris or in the literature: (1) 10-30 ka BP: modern humans: Paleolithic; (2) 90-200 ka BP: anatomically modern humans; (3) 45-90 ka BP: Neanderthals; (4) 1.5 Ma BP: Homoergaster; These skulls are all well kept and possess a jaw in the majority of cases but the vertebral column has been reconstituted. We attempt to: (1) Localize hyoid bone and then glottis position; (2) Reconstitute a vocal tract model in a plausible way using an articulatory model; (3) Quantify the acoustic capabilities of this reconstituted vocal tract. …”
