| Outline of Final Research Achievements |
Individual differences in auditory-visual speech perception in people with hearing loss were investigated using syllables, words and sentences. The stimuli were presented in auditory-only, visual-only, and auditory-visual mode of stimulation for both congruent and incongruent conditions. Nine young adults with hearing-aids or cochlear implants participated in the study. The relative increase in auditory-visual speech perception due to the addition of visual cues to the auditory signal was calculated for each condition. Results show that the subjects were able to integrate both auditory and visual cues in the auditory-visual congruent condition. The auditory-visual gain in speech perception was reduced in the incongruent condition. The subjects showed significant individual differences in the amount of gain for different experimental conditions.
