Speech sources localization based on microphone array is the basic for extraction of the interesting speech source, which is applied broadly in multimedia communication. In this paper, the methods for speech sources localization based on uniform linear array and on uniform circular array are discussed, and their digital simulation have been taken. The simulation results show that they can effectively extract the localization of speech source. The hardware scheme to implement these algorithms have been given in this paper.
