Abstract:
1. An apparatus for detecting endpoints of a plurality of sound signals from a plurality of sound sources, the apparatus comprising: a plurality of microphones configured to receive the plurality of sound signals from the plurality of sound sources; a sound source position detecting unit configured to detect positions of the plurality of sound sources from the sound signals received through the plurality of microphones; a sound source position change determination unit configured to determine a change in position of the sound sources according to each direction by reading the positions of the plurality of sound sources detected through the sound source position detecting unit; a sound source maintenance time calculating unit configured to calculate a sound source maintenance time of the sound sources at a specific position by reading the positions of the plurality of sound sources detected through the sound source position detecting unit; and an endpoint determination unit configured to determine endpoints of the plurality of sound sources by use of the sound source maintenance time calculated by the sound source maintenance time calculating unit and the change in position of the sound sources according to each direction determined by the sound source position change determination unit.
