| Research Abstract |
This study introduces an approach that makes speech announcements intelligible for older adults and non-native listeners in reverberant public spaces(e. g., train stations). This approach is based on the way we change how we speak depending in a noisy environment. Listening tests with young and older adults showed that speech spoken in noisy/reverberant environments was statistically intelligible than speech spoken in a quiet environment(i. e., normal speech announcements) with background noise/reverberation conditions(signal to noise ratios were-2 and 0 dB, and reverberation times were from 1.4 to 3.6 s). The results suggest that using speech spoken in noise/reverberation for public address systems makes speech announcements more intelligible in public spaces.
