This book is one outcome of the NATO Advanced Studies Institute
(ASI) Workshop, "Speechreading by Man and Machine," held at the
Chateau de Bonas, Castera-Verduzan (near Auch, France) from August
28 to Septem ber 8, 1995 - the first interdisciplinary meeting
devoted the subject of speechreading ("lipreading"). The forty-five
attendees from twelve countries covered the gamut of speechreading
research, from brain scans of humans processing bi-modal stimuli,
to psychophysical experiments and illusions, to statistics of
comprehension by the normal and deaf communities, to models of
human perception, to computer vision and learning algorithms and
hardware for automated speechreading machines. The first week
focussed on speechreading by humans, the second week by machines, a
general organization that is preserved in this volume. After the in
evitable difficulties in clarifying language and terminology across
disciplines as diverse as human neurophysiology, audiology,
psychology, electrical en gineering, mathematics, and computer
science, the participants engaged in lively discussion and debate.
We think it is fair to say that there was an atmosphere of
excitement and optimism for a field that is both fascinating and
potentially lucrative. Of the many general results that can be
taken from the workshop, two of the key ones are these: * The ways
in which humans employ visual image for speech recogni tion are
manifold and complex, and depend upon the talker-perceiver pair,
severity and age of onset of any hearing loss, whether the topic of
conversation is known or unknown, the level of noise, and so forth.
