Claim 12:
13. The position detection method of claim 3, wherein the identifying projection energies of the voice signals corresponding to each of the plurality of predefined positions, based on the projection energy of each of the plurality of frequency bins corresponding to each of the plurality of predefined positions and the weight of each of the plurality of frequency bins, comprises:
weighting the projection energy of each of the plurality of frequency bins corresponding to each of the plurality of predefined positions based on the weight of each of the plurality of frequency bins; and
summating the weighted projection energy of each of the plurality of frequency bins corresponding to each of the plurality of predefined positions to obtain the projection energies of the voice signals corresponding to the plurality of predefined positions.
