Speechreading by Humans and Machines

This is the first comprehensive book on the interdisciplinary study of speechreading (lipreading) -- production, perception and learning -- by both humans and machines. It is the product of the largest-ever gathering of scientists devoted to the subject, at a NATO workshop held in France in 1995. The research presented explores and promotes the incorporation of visual information into automatic speech recognizers for improved recognition accuracy (especially in noisy environments), and draws on and further elucidates knowledge of the psychology of speechreading by humans. The book is a milestone along the path to more accurate speech based interfaces, as well as to deeper understanding of fundamental mechanisms of human perception and speech recognition.
