SOUND DIRECTION ESTIMATION DEVICE, SOUND PROCESSING SYSTEM, SOUND DIRECTION ESTIMATION METHOD, AND SOUND DIRECTION ESTIMATION PROGRAM |
摘要 |
A sound direction estimation device includes a first correlation matrix calculation unit configured to calculate a correlation matrix of a plurality of channels of input sound signals, a second correlation matrix calculation unit configured to calculate a correlation matrix of noise signals based on the plurality of channels of sound signals, and a sound source localization unit configured to calculate a spatial spectrum based on the correlation matrix calculated by the first correlation matrix calculation unit and the correlation matrix calculated by the second correlation matrix calculation unit and to estimate a direction of a sound source associated with the plurality of channels of sound signals using the calculated spatial spectrum. |
