Abstract: This paper proposes a machine-learning based technique to investigate the significance of the dynamic information for visual perception of consonants. The visual speech information can be described using static (facial appearance) or dynamic (movement) features. The aim of this research is to determine the saliency of dynamic information represented by the lower facial movement for visual speech perception. The experimental results indicate that the facial movement is distinguishable for nine English consonants with a success rate of 85% using the proposed approach. The results suggest that time-varying information of visual speech contained in lower facial movements is useful for machine recognition of consonants and may be an essential cue for human perception of visual speech.
