No one doubts the importance of the face in social interactions, but p
eople seldom think of it as playing much of a role in verbal communica
tion. A number of observations suggest otherwise, though: Many people
dislike talking over the telephone and are irritated by poorly dubbed
foreign films. Some people even comment that they hear the television
better with their glasses on. Children born blind learn some speech di
stinctions more slowly than their sighted cohorts. It has been well kn
own for some time that the deaf and hearing impaired can make valuable
use of lipreading, which is better termed speechreading, but more rec
ently investigators have shown that even people with normal hearing ar
e greatly influenced by the visible speech in face-to-face communicati
on. Our research is aimed at understanding how people perceive speech
by both ear and eye.
