SKULLSPEECH - Acquisition et contrôle articulatoire de la parole, croissance de l'extrémité céphalique du nouveau-né jusqu'à l'âge adulte

Project Coordinator : Pascal PERRIER

Project realized thanks to the support of : ANR Blanc

Start date : 2009/01/01

Duration : 48 mounths

SkullSpeech is organized in four parts:
1. The description and the modeling of the growth during ontogenesis of the skull and cervical spine and the soft tissues that delimit the vocal tract;
2. The evaluation of the mechanical tongue-teeth-palate interactions and study of the impact of the physiological functions (feeding, mastication, breathing and speech production) on the morphogenesis of the vocal tract and the bony structures.
3. The analysis and the acoustic synthesis, using a 2D geometrical and a 3D mechanical model of the vocal tract, of babbling and syllabic structures (stop consonants-vowels) which constitute the first utterances of a child from 7 months to 2 years.
4. The study of the dental occlusions; the diagnosis of the basicranial origin of malocclusions and consequently their impact on speech production. As a consequence, we will be able to better understand the speech dysfunctions, and/or orthodontic diseases which affect more and more children nowadays.

SkullSpeech focuses on the relation between skull growth and the control and mechanisms that coordinate tongue and mandible. These mechanisms are implemented during a specific period of growth, the first two years of life; they are crucial to better understand speech acquisition and also speech emergence for human species.
SkullSpeech puts special effort on data acquisition and modeling.
To facilitate the dissemination of the results among researchers (speech scientists, (paleo)anthropologists, anatomists), physicians and orthodontists, we provided throughout SkullSpeech an important effort for elaborating dynamic illustrations (computer graphics) of the processes of growth of the skull and of the soft tissues and the evolutions of the vocal tract. We will add selected video tapes of speech acquistion stages.

SkullSpeech is an original multidisciplinary project associating the domains of anatomy, physical anthropology, biomechanical modeling of the control of articulators, of speech acquisition and production of speech and dento-facial orthopedy.
