Abstract: Many kinds of sound source localization systems have been developed for detecting a direction of sound source. They are commonly using time delay of arrival (TDOA) or interaural time difference (ITD) algorithm for sound source localization where, especially, the ITD is the dif- ference in arrival time of a sound between two ears. It is largely changed depending on frequency components of sound even though the sound source is located in the same place. In this paper we propose a binaural sound localization system using sparse coding based ITD (S- ITD) and self-organizing map (SOM). The sparse coding is used for decomposing given sounds into three compo- nents: time, frequency and magnitude. Moreover we es- timate the azimuth angle through the SOM. This local- ization system is installed in our robot that has two ears, head and body. We use PeopleBot as a body of the robot.
