In order to synthesize natural change of various and continuous strengths of singing voice expressions, a singing voice without expression, "normal," is used as the base of morphing, and singing voices of the particular singer with three different expressions, "dark," "whispery" and "wet," are used as targets. The results of the paired comparison between different strengths of vocal timbre suggested that the decrease of the expression in vocal timbre is more perceived than the increase in some expressions.AA1221543X情報処理学会研究報告ヒューマンコンピュータインタラクション(HCI)200850(2008-HCI-128)25302008-05-212009-06-30
