Abstract

Older adults have difficulty understanding speech in challenging listening environments. Combining multisensory signals may facilitate speech recognition. This study measured recognition of interrupted spoken and written sentences by older adults for different preserved stimulus proportions. Unimodal performance was first examined when only interrupted text or speech stimuli were presented. Multimodal performance with concurrently presented text and speech stimuli was tested with delayed and simultaneous participant responses. Older listeners performed better in unimodal speech-only compared to text-only conditions across all proportions preserved. Performance was also better in delayed multimodal conditions. Comparison to a younger sample suggests age-related amodal processing declines.
