音声信号におけるゆらぎ値等の特徴量と感性的印象との相関性に関する研究 Research on Correlation between Feature Quantity of Sound Signal and Kansei Impression 川上, 裕介 カワカミ, ユウスケ Kawakami, Yusuke open access 音声処理 ゆらぎ値 切片 残差二乗和 回帰分析 感性的印象 HMGD Sound processing fluctuation value intercept sum of squared errors regression analysis Kansei impression HMGD Abstract This research investigates the correlation between feature quantity of sound signal and human Kansei impression or affective impression. In this research, we regard the feature quantity as three kinds of values, that is, fluctuation value, intercept, and sum of squared errors that are obtained by making a regression analysis of sound signal in the Fourier domain. Also, we analyse the correlation not only for all frequency domain, but also for each of three divided frequency domains, that is, low frequency band, middle frequency band, high frequency band in the Fourier domain. Moreover, we examine as to how the human impression changes depending on the cases where the aforementioned feature quantity is artificially varied by sound processing. And we examine as to how the Kansei impression changes of the sound signal at the time of performing the HMGD processing. As its application, we present HMGD processing example to colour image. あらまし 本研究では，音声信号のフーリエ領域における回帰分析によって算出される，ゆらぎ値，切片，残差二乗和の 3 つの特徴量等と音声信号の感性的印象との相関性を調査する．また本研究では，全周波数帯域，低域，中域，高域における各々の特徴量と音声の感性的印象との関係についても詳細に分析する．更には，特徴量を人為的に変更した場合に応じた感性的印象の変化についても調査分析を行う．また，HMGD 処理を行った際の音声信号の感性的印象の変化も調査し，応用としてカラー画像への HMGD 処理例を示す． jpn doctoral thesis VoR https://kagawa-u.repo.nii.ac.jp/records/219 https://dl.ndl.go.jp/pid/10224390 500000993754 甲第97号 博士（工学） 2014-09-30 16201 香川大学 Kagawa University https://kagawa-u.repo.nii.ac.jp/record/219/files/Eng_A97.pdf application/pdf 5.3 MB 2020-10-27 https://kagawa-u.repo.nii.ac.jp/record/219/files/Eng_A97_abstract_result.pdf application/pdf 323.9 kB 2020-10-27
