A novel method for tracking the direction of arrival of a moving speech source is proposed. The technique involves extracting from the received speech signals certain cyclostationary parameters and application of the blind cyclic adaptive beamforming (CAB) algorithm to steer the beam towards the speech source. The fast convergence and computational simplicity of the CAB algorithms are exploited to track the spatially non-stationary and temporally cyclostationary source.
