Abstract
In this paper, we present the 3D acquisition infrastructure we developed for building a talking face and studying some aspects of visual speech. A short-term aim is to study coarticulation for the French language and to develop a model which respects a real talker articulation. One key factor is to be able to acquire a large amount of 3D data with a low-cost system more flexible than existing motion capture systems (using infrared cameras and glued markers). Our system only uses two standard cameras, a PC and painted markers that do not change speech articulation and provides a sufficiently fast acquisition rate to enable an efficient temporal tracking of 3D points. We present here our stereovision data capture system and how these data can be used in acoustic-to-articulatory inversion

the 3D acquisition infrastructure we developed for building a talking face and studying some aspects of visual speech. A short-term aim is to study coarticulation for the French language and to develop a model which respects a real talker articulation. One key factor is to be able to acquire a large amount of 3D data with a low-cost system more flexible than existing motion capture systems (using infrared cameras and glued markers). Our system only uses two standard cameras, a PC and painted markers that do not change speech articulation and provides a sufficiently fast acquisition rate to enable an efficient temporal tracking of 3D points. We present here our stereovision data capture system and how these data can be used in acoustic-to-articulatory inversion</div></front></TEI><affiliations><list><country><li>France</li></country><region><li>Grand Est</li><li>Lorraine (région)</li></region><settlement><li>Nancy</li></settlement><orgName><li>Institut national polytechnique de Lorraine</li><li>Université Nancy 2</li><li>Université de Lorraine</li></orgName></list><tree><country name="France"><region name="Grand Est"><name sortKey="Wrobel Dautcourt, Brigitte" sort="Wrobel Dautcourt, Brigitte" uniqKey="Wrobel Dautcourt B" first="Brigitte" last="Wrobel-Dautcourt">Brigitte Wrobel-Dautcourt</name></region><name sortKey="Berger, Marie Odile" sort="Berger, Marie Odile" uniqKey="Berger M" first="Marie-Odile" last="Berger">Marie-Odile Berger</name><name sortKey="Laprie, Yves" sort="Laprie, Yves" uniqKey="Laprie Y" first="Yves" last="Laprie">Yves Laprie</name><name sortKey="Ouni, Slim" sort="Ouni, Slim" uniqKey="Ouni S" first="Slim" last="Ouni">Slim Ouni</name><name sortKey="Potard, Blaise" sort="Potard, Blaise" uniqKey="Potard B" first="Blaise" last="Potard">Blaise Potard</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
