Verification of sound source localization in reverberation room and its real time adaptation using visual information

Abstract

It is important for intelligent robots to detect the location of user even though the user is not captured by vision cameras. Sound source localization is a technique to detect the direction of sound source using multiple microphones. It enables the robot to respond to the user's call. Sometimes, a robot operates in echoic room, but the performance of sound source localization in echoic room is very poor. In this work, a verification method for reverberation is proposed and tested how much it improves the performance of sound source localization in reverberant environment.
