Outline of Final Research Achievements

This study (1) linguistically analyzed evacuation calls and (2) investigated the effects of acoustic characteristics of spoken evacuation calls on perception. As a result of (1), it was revealed that the amount of language in a call was greater in flood/land slide evacuation calls than in tsunami calls and that the number of complex sentences in a call increases as the alert level goes up. As a result of (2), it was found that generally, female voice with normal pitch and speed obtained the highest rate in terms of perceived intelligibility, reliability, and urgency; however, faster speech was the most effective for perceived urgency.
