| Abstract(in English) | In this paper, the signal processing technique based on cross-correlation function which an utterer direction is detected from the first wave front of the voice, is experimentally discussed. The distinction between voise/hai/and noise is done by setting the threshold level and analyzing the cepstrum. As a result, the average detection rate of utterer's direction is 92% over SNR=-5dB, according to setting the BPF and threshold level. Moreover, by means of analyzing each cepstrum value from the 0th to 9th quefrency, the detection rate of voice on the first wave front is 95% regardless of the man or woman, and it can be said that this technique is effective in this system. |
