Distinguishing True and False Source Locations when Localizing Multiple Concurrent Speech Sources

Swartling, Mikael LU ; Nilsson, Mikael LU and Grbic, Nedelko LU (2008) 2008 IEEE Sensor Array and Multichannel Signal Processing Workshop In 2008 5th IEEE Sensor Array and Multichannel Signal Processing Workshop p.361-364
Abstract
A permutation problem arises in the case of locating multiple speech sources using several sensor arrays in the far field. The intersection of different direction of arrival (DOA) estimates between sensor arrays leads to a set of real source locations as well as a set of false intersections. This paper presents a novel method for pairing DOA estimates from different sensor arrays, resulting in the corresponding real intersection points. The algorithm presented is numerically efficient and suitable for real time implementations. Real room recordings are used to evaluate the method.
