This research focuses on the spatio-temporal characteristics of lips and jaw movements and on their relevance for lip-reading, bimodal communication theory and bimodal recognition applications. 3D visible articulatory targets for vowels and consonants are proposed. Relevant modifications on the spatiotemporal consonant targets due to coarticulatory phenomena are exemplified. When visual parameters are added to acoustic ones as inputs to a Recurrent Neural Network system, high recognition results in plosive classification experiments are obtained.
