Abstract—This paper report that the implementation of the speaker direction detector using a small and low-priced micro controller called ”dsPIC ” and propose the speaker localization method integrating the results from the multiple detectors. To confirm a basic performance of the proposed method, an experiment for estimating 6 locations at intervals of 1m using a pair of the speaker direction detectors is conducted. The experimental results show a good prospect of the proposed method using the small and low-priced devices.
