AMULET: automatic multisensor speech labelling and event tracking: study of the spatio-temporal correlations in voiceless plosive production

Speech production is a complex process relying on coordinated gestures, but the acoustic signal does not depict its underlying organization. Accepting that articulatory gestures are directly recognized through the coarticulation process, our proposal is to investigate the correlations between acoustic and articulatory information and to assess gestural phonetic theory. We present the framework for this investigation, the automatic articulatory labelling of the multi sensor speech database ACCOR, and the study of the spatio temporal correlations in the voiceless plosive production
