ABSTRACT

This paper presents a viable solution for the Sound Source Localization (SSL) problem. The aim of this paper is to develop a computationally viable approach to find the coordinate location of a sound source with acceptable accuracy when using a compact microphone array that can be mounted on top of a small moving robot. The approach suggested in this paper uses the SRP-PHAT algorithms in its core and it comprises two stages: the first stage contracts the search space by estimating the Direction of Arrival (DoA) vector using the near field model which in turn is used to form a smaller search region, the second stage is to use the SRP-PHAT algorithm to search this contracted region for the source location. The AV16.3 corpus was used to test the approach by running extensive experiments. The results are reported and it proves the effectiveness of this approach
