Sound source separating device and sound source separating method
First Claim
1. A sound source separating device comprising:
- a sound collecting unit configured to collect sound signals using a plurality of microphones;
a sound source localizing unit configured to localize a sound source on the basis of the sound signals collected by the sound collecting unit;
a sound source separating unit configured to separate the sound signals collected by the sound collecting unit into sound sources corresponding to a number of fixed sound sources and fixed sound source directions without using the sound source localization result from the sound source localizing unit; and
a speech extracting unit configured to extract speech signals of the fixed sound sources on the basis of the sound source localization result from the sound source localizing unit and the sound source separation result from the sound source separating unit.

Abstract
A sound source separating device includes: a sound collecting unit configured to collect sound signals using a plurality of microphones; a sound source localizing unit configured to localize a sound source on the basis of the sound signals collected by the sound collecting unit; a sound source separating unit configured to separate the sound signals collected by the sound collecting unit into sound sources corresponding to the number of fixed sound sources and fixed sound source directions without using the sound source localization result from the sound source localizing unit; and a speech extracting unit configured to extract speech signals of the fixed sound sources on the basis of the sound source localization result from the sound source localizing unit and the sound source separation result from the sound source separating unit.

10. A sound source separating method comprising:
-
a sound collecting step of collecting sound signals using a plurality of microphones; a sound source localizing step of localizing a sound source on the basis of the sound signals collected in the sound collecting step; a sound source separating step of separating the sound signals collected in the sound collecting step into sound sources corresponding to the number of fixed sound sources and fixed sound source directions without using the sound source localization result in the sound source localizing step; and a speech extracting step of extracting speech signals of the fixed sound sources on the basis of the sound source localization result in the sound source localizing step and the sound source separation result in the sound source separating step.
