Errors in judging by 9 men and 9 women the three acoustic cues for consonant 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.
