Traditional methods, connected with use of one microphone as an input of speech signal into a computer, do not give us a high reliability of recognition. If signal-to-noise relation (SNR) is 0-6 dB, the probability of an error even in identification of speech activity using only one microphone in typical cases is not less than 10% (as experiments and literature data show). ... The far-positioned (third) microphone can be used to estimate the average level of an external noise. ...
