Abstract
A novel method for tracking the direction of arrival of a moving speech sou rce is proposed. The technique involves extracting from the received speech signals certain cyclostationary parameters and application of Uk blind cyc lic adaptive beamforming (CAB) algorithm to steer the he;un towards the spe ech source. The fast convergence and computational simplicity of the CAB al gorithms are exploited to track the spatially non-stationary and temporally cyclostationary source.
