| Outline of Final Research Achievements |
We have designed and built a speech database for emotional utterances in dementia care based on survey on utterances that frequently appear in dementia care workplaces,. In parallel, we developed a method of generating emotional speech stimuli, in which the contour of fundamental frequency derived from original speech utterance is flattened gradually.
A series of listening tests were conducted with the cooperation of 24 healthy elderlies (12 males, 12 females, 65-81 years old) and 14 dementia patients (1 male, 13 females, 58-93 years old) as experimental subjects. It has been found out that the dementia persons’ capability of cognition for emotions from speech is degraded compared with healthy persons’ significantly, and that the difference was made even in emotion strength of original speech. In addition, remarkable degradation in the correct answer rate has been observed for the emotion-type pair, anger and happiness.

| Academic Significance and Societal Importance of the Research Achievements |
本成果により、特に「喜び」、「怒り」等の感情的内容の伝達に関し、認知症患者との音声によるコミュニケーションを維持するための基礎的知見を得た。これを、介護家族や介護職員等がコミュニケーションを取る際に、どのような「話しかけ方」が認知症患者との意思疎通や信頼関係の構築に有用であるかの指針に反映することが期待できる。
また、構築した認知症介護発話音声データベースは、一般的な感情音声コーパスとしての用途も含め、広く活用が期待できる。
