This report describes the research and development of speaker localisation to locate the position of a person speaking. Two closed-form localisation techniques were analysed, the first was developed by Schau and Robinson 1987 based on spherical intersection and the other developed by Chan and Ho 1994. Both techniques are based on time difference of arrival measurements. Accordingly three time delay estimators, namely cross-correlation, generalised cross-correlation, and an eigenvalue decomposition based algorithm were analysed. The implementation of the algorithms in Matlab and the results from the analyses are discussed.
