- W2969802502 abstract "本研究では, 感情と音声中の音響的特徴の関係を調べている. 本報では語頭の [え] に“驚き”,“喜び”,“怒り”,“嫌悪”の4つの感情をこめて発声した場合と, こめない場合の音声データを分析して, 波形の概形とピッチ周期およびスペクトル包絡線の傾斜の時間変化を調べた. その結果, 変化幅, 変化率などの特徴量に感情による違いがみられた. 次に, 分析結果をもとにして, ピッチ周期やスペクトル包絡線の傾斜の変化率を変えて合成音をつくり, 聞き取り実験を行った. その結果, 聞き取りの印象に大きな違いがみられたのは“驚き”のピッチ周期の変化率を変えた場合で, 変化率が大きいほうが“驚き”の感情の聞き取りは良くなることがわかった." @default.
