Abstract:
(EN) This voice articulation calculation method is executed by a voice articulation calculation device, and includes: a voice articulation calculation step for calculating voice articulation, which is an objective evaluation index for voice quality, on the basis of a difference component of feature amounts determined by analysis, using one or a plurality of filter bands, of a clean voice and an emphasized voice that have been input; and a step for outputting the voice articulation that was calculated in the voice articulation calculation step. The voice articulation calculation method can calculate voice articulation with good precision, without relying on a voice emphasis method.
(FR) La présente invention concerne un procédé de calcul d'articulation vocale, qui est exécuté par un dispositif de calcul d'articulation vocale, et qui comprend : une étape de calcul d'articulation vocale consistant à calculer une articulation vocale, qui constitue un indice d'évaluation objective de la qualité vocale, sur la base d'une composante de différence de quantités caractéristiques déterminées par l'analyse, à l'aide d'une ou plusieurs bandes de filtre, d'une voix normale et d'une voix accentuée ayant été entrées ; et une étape de fourniture de l'articulation vocale qui a été calculée dans l'étape de calcul d'articulation vocale. Le procédé de calcul d'articulation vocale peut calculer une articulation vocale avec une bonne précision, sans se baser sur un procédé d'accentuation vocale.
(JA) 音声明瞭度計算方法は、音声明瞭度計算装置が実行する音声明瞭度計算方法であって、入力されたクリーン音声と強調音声とを、1または複数のフィルタバンクを用いた分析で求めた特徴量の差分成分を基に、音声品質の客観評価指標である音声明瞭度を計算する音声明瞭度計算工程と、音声明瞭度計算工程において計算された音声明瞭度を出力する工程と、を含み、音声強調方法に依存することなく音声明瞭度を精度よく計算することができる。
