Endpoint detection apparatus for sound source and method thereof

摘要

An apparatus for detecting endpoints of sound signals when sound sources vocalized from a remote site are processed even if a plurality of speakers exists and an interference sound being input from a direction different from a direction of one speaker, and a method thereof, wherein in an environment in which a plurality of sound sources exists, the existence and the length of the sound source being input according to each direction is determined and the endpoint is found, thereby improving the performance of the post-processing, and speech being input from a direction other than a direction of speech from a speaker vocalized at a remote area from a sound source collecting unit is distinguished while the speech from the speaker is being recorded, thereby enabling a remote sound source recognition without restriction on the installation region of a microphone.
