Abstract:
(EN) [Problem] To provide a system for evaluating the appropriateness of an adopted noise segment. [Solution] An information processing device comprising: an acquisition unit for acquiring an audio signal representing a collection result for sounds collected by a sound collection device group; and a control unit that calculates a first weight in accordance with a degree of matching between the audio signal acquired by the acquisition unit and a signal acquired by observing a stationary noise and applies the first weight to a noise spatial correlation matrix which is the spatial correlation matrix acquired from a noise signal.
(FR) [Problème] Fournir un système d'évaluation de l'adéquation d'un segment de bruit adopté. [Solution] L'invention concerne un dispositif de traitement d'informations comprenant : une unité d'acquisition pour acquérir un signal audio représentant un résultat de collecte pour des sons collectés par un groupe de dispositifs de collecte de sons ; et une unité de commande qui calcule un premier poids conformément à un degré de correspondance entre le signal audio acquis par l'unité d'acquisition et un signal acquis en observant un bruit stationnaire et applique le premier poids à une matrice de corrélation spatiale de bruit qui est la matrice de corrélation spatiale acquise à partir d'un signal de bruit.
(JA) 【課題】採用された雑音区間の適切さを評価する仕組みを提供する。 【解決手段】収音装置群による収音結果を示す音響信号を取得する取得部と、前記取得部により取得された前記音響信号が定常雑音を観測した信号である度合に応じた第1の重みを計算し、前記第1の重みを雑音信号から得られる空間相関行列である雑音空間相関行列に適用する制御部と、を備える情報処理装置。
