Three measures of auditory‐visual (AV) integration using both congruent and discrepant speech stimuli were evaluated in 30 hearing‐impaired subjects. The first measure was based on Braida’s model of pre‐labeling integration [Q. J. Exp. Psych.43, 647–677 (1991)] which makes predictions of AV consonant recognition from separate auditory (A) and visual (V) consonant confusion matrices. The ratio of observed‐to‐predicted AV score was used as an index of integration, with unity representing optimal integration. The second measure used discrepant A and V consonant–vowel stimuli to determine susceptibility to ‘‘McGurk’’ effects. Susceptibility was defined as the difference between A and AV consonant recognition, with greater differences reflecting greater susceptibility. The third measure used temporally misaligned AV speech stimuli in a sentence recognition task to determine individual sensitivity to AV asynchrony. Auditory onset delays between 0‐320 ms were studied and individual sensitivity to AV asynchrony was defined in terms of decrements in sentence intelligibility relative to the synchronous condition (0‐ms delay). Relations among these three potential measures of AV integration, and between integration measures and a separate measure of relative AV sentence benefit, will be discussed.
