The efficiency of speech recognizers depends in a great extent en the background noise. In this paper 3 very simple, but useful methods are presented for decreasing the effects of the background noise: 1 - correlated averaging technique using 2 or more pressure microphones 2 - speaker adaptiv filtering, using one preasure gradient Microphone, 3 - speech signal separation from the disturbing impulse-noise, using one pressure and one pressure-gradient microphones.
