Outline of Final Research Achievements

[ 1. Development of daily conversation database ] To archieve a conversation characteristic model, we recorded the 125 sets ( 100 sets of elderly persons, 25 sets of young persons ) of daily conversation for 3 minutes by microphone and video camera. The database includes these speech and image files and the results of acoustic and image analyses. [ 2. Analysis of acoustic and image characteristics ] We confirmed the fundamental frequency values the SLP by rach utterance, and the synchronization degrees of gestures are useful for estimating the age-dependent degradation. [ 3. Proposal of an age-dependent degradation estimation method] We proposed an age-dependent degradation estimation method using the acoustic and image features of responce utterances of daily conversation. The reason of using these features are that we confirmed these acoustic and image features are effective to distinguish whether elderly persons understand their partner's speech or not understand them.

Academic Significance and Societal Importance of the Research Achievements

[学術的意義] 場の雰囲気や気配などを理解するモデル構築は、音声や画像などの特徴を単独で利用するだけでは不十分であり、複数パラメータの組合せや相互作用により実現できる。複数パラメータの相互作用モデルの構築として意義が深い。
[社会的意義] 年々割合が増加している高齢者の交通死亡事故の原因は、「運転操作不適」であり、高齢者に「衰え」の自覚がなく自らを過信している問題を指摘する声もある。さりげなく衰えを察知し本人に警鐘を促すことができるモデルの実現は、上記高齢者事故の削減に妻がるものとして意義が深い。
