Speech intelligibility and spatial information

[Al Bregman <al.bregman@xxxxxxxxx>]

Dear list,

Does anybody know the answer to this?

Suppose a person (P) is talking in a background of other speech
sounds.  Does anybody know of data that tell whether  the
intelligibility of P's speech  increases when the listener is
presented with visual information which gives the exact location
of P in space?  There is a computer model by Nakagawa, Okuno, and
Kitano (AAAI-99)  that makes this assumption, but are there any
data on human listeners?  I am asking only about spatial
information supplied by vision, not spatial information derived
by the auditory system from the signal itself.

Al
