Abstract

The emergency disaster information is understood when it is read aloud by a speech-sound following an alerting chime. At that time, are auditory agnosia who have difficulty recognizing speech-sounds able to grasp disaster information? To answer this question, I conducted two audiovisual experiments in which 74 persons with auditory agnosia and 42 persons without auditory agnosia were asked to answer the question of a speech-sound task created in multimedia DAISY format. As a result, correct answers were obtained in the first half of the experiment, even though the subjects had difficulty recognizing speech-sounds. However, mistakes were noticeable in the second half. From these results, it was found that if multisensory integration is used, persons with auditory agnosia can grasp information even with ordinary speech-sounds, however, it becomes difficult to grasp speech-sounds over time.
