Abstract:
(EN) A signal processing device is provided with a first microphone, a second microphone and a signal processing unit. The signal processing unit performs echo removal processing for at least one of a collected sound signal of the first microphone and a collected sound signal of the second microphone, and determines, using signals after echo has been removed by the echo removal processing, a correlated component between the collected sound signal of the first microphone and the collected sound signal of the second microphone.
(FR) L’invention concerne un dispositif de traitement de signal doté d’un premier microphone, d’un deuxième microphone et d’une unité de traitement de signal. L’unité de traitement de signal exécute un traitement d’élimination d’écho pour au moins un signal parmi un signal sonore collecté sur le premier microphone et un signal sonore collecté sur le deuxième microphone, puis détermine, en utilisant les signaux sur lesquels l’écho a été éliminé par le traitement d’élimination d’écho, une composante corrélée entre le signal sonore collecté sur le premier microphone et le signal sonore collecté sur le deuxième microphone.
(JA) 信号処理装置は、第1マイクと、第2マイクと、信号処理部と、を備えている。信号処理部は、前記第1マイクの収音信号または前記第2マイクの収音信号の少なくともいずれかに対して、エコー除去処理を行ない、該エコー除去処理でエコーを除去した後の信号を用いて、前記第1マイクの収音信号および前記第2マイクの収音信号の相関成分を求める。
