The audio-visual models used in existing AVSR systems, as well as the audio-visual models discussed in this pa- per, are special cases of dynamic Bayesian networks (DBN) [5, 21, 22]. DBNs are directed graphical models of stochas- tic processes in …

Abstract. Audio-Visual speaker recognition promises higher performance than any single modal biometric systems. This paper further improves the novel approach based on Dynamic Bayesian Networks (DBNs) to bimodal speaker recognition. In the present paper, we investigate five different topologies of feature-level fusion framework using DBNs.

The use of visual features in audio-visual speech recognition (AVSR) is justified by both the speech generation mechanism, which is essentially bimodal in audio and visual representation, and by the need for features that are invariant to acoustic noise perturbation. As a result, current AVSR systems demonstrate significant accuracy improvements in environments …
