L. Berryman et al., AN EXAMINATION OF ERROR REDUCTIONS IN CONSONANT RECOGNITION WHEN VISION AND HEARING ARE COMBINED, Perceptual and motor skills, 82(2), 1996, pp. 558-558
Errors in judging by 9 men and 9 women the three acoustic cues for con
sonant recognition, those of voice, place of articulation, and manner
of articulation, were markedly reduced by 70% or more when vision was
added to hearing in a word-in-noise discrimination task. The extent of
error reduction is surprising especially for the least-visible voice
cue.
