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.
