Title (EN) PERFORMANCE EVALUATION DEVICE, PERFORMANCE EVALUATION METHOD, AND PERFORMANCE EVALUATION PROGRAM
(FR) DISPOSITIF, PROCÉDÉ, ET PROGRAMME D'ÉVALUATION DE PERFORMANCE
(JA) 演奏評価装置、演奏評価方法および演奏評価プログラム
Abstract:
(EN) A performance evaluation device includes a determination unit and a detection unit. The determination unit determines whether or not the pitch of a performed sound generated from an instrument played by a user is different from the pitch of a sound that should be produced and the pitch belongs to the harmonic series of the pitch of the sound that should be produced. The detection unit detects a playing technique or playing error on the basis of a change in the pitch of the performed sound when the pitch of the performed sound is different from the pitch of the sound that should be produced and belongs to the harmonic series of the pitch. The change in the pitch of the performed sound may be the periodicity of the pitch of the performed sound.
(FR) L'invention concerne un dispositif d'évaluation de performance comprenant une unité de détermination et une unité de détection. L'unité de détermination détermine si le ton d'un son émis produit par un instrument joué par un utilisateur est différent du ton d'un son devant être produit et si le ton appartient à la série harmonique du ton du son devant être produit. L'unité de détection détecte une technique d'interprétation ou une erreur d'interprétation sur la base d'un changement du ton du son émis lorsque le ton du son émis est différent du ton du son devant être produit et appartient à la série harmonique du ton. Le changement du ton du son émis peut être la périodicité du ton du son émis.
(JA) 演奏評価装置は、判定部および検出部を備える。判定部は、ユーザにより演奏される楽器から発生された演奏音の音高が本来発生されるべき音の音高と異なりかつ本来発生されるべき音の音高の倍音列に属するか否かを判定する。検出部は、演奏音の音高が本来発生されるべき音の音高と異なりかつ倍音列に属する場合に、演奏音の音高の変化に基づいて演奏技法または演奏誤りを検出する。演奏音の音高の変化は演奏音の音高の周期性であってもよい。
