| Abstract(in English) | In this paper, we propose a method to reduce background noise from noisy speech by doing the processing of the spectral subtraction firstly and the blind signal separation secondly in the frequency domain. Because we assume that the second signal spectrum play an important role in the blind signal separation, we examine about the generation of the signal spectrum that includes many elements of background noise in real-world, and show the effect of noise reduction. Moreover, we show the difference of the effect in noise reduction in the part of speech and noise by the difference of the sample numbers of DFT in the experiment used the real-speech. |
