Abstract
(EN)
This acoustic analysis device includes a feature acquisition unit for acquiring a feature amount time series for an acoustic signal and a boundary estimation model that is a learned model which is trained on the relationship between the feature amount time series and boundary data indicating the boundary of a continuous section in which the same chord continues, and that generates the boundary data in response to the input of the feature amount time series for the acoustic signal.
(FR)
Ce dispositif d'analyse acoustique comprend : une unité d'acquisition de caractéristiques permettant d’acquérir une série chronologique de quantité de caractéristiques pour un signal acoustique ; et un modèle d'estimation de limite qui est un modèle appris qui est formé à la relation entre la série chronologique de quantité de caractéristiques et les données de limite indiquant la limite d'une section continue dans laquelle le même accord se poursuit, et qui génère les données de limite en réponse à l'entrée de la série chronologique de quantité de caractéristiques pour le signal acoustique.
(JA)
音響解析装置は、音響信号の特徴量の時系列を取得する特徴取得部と、特徴量の時系列とコードが継続する連続区間の境界を表す境界データとの関係を学習した学習済モデルであって、音響信号の特徴量の時系列の入力に対して境界データを生成する境界推定モデルを具備する。
