FIELD: radio engineering. ^ SUBSTANCE: method for recognition of voice including reception of frames that contain samples of audio signal; formation of criteria vector that contains the first number of vector components for each frame; projection of criteria vector at least at two subspaces so that number of components in each projected vector of criteria is less than the first number, and common number of components in projected vector of criteria is equal to the first number; establishment of mixing models set for each projected vector, which provides for highest probability of observation; and analysis of mixing models set for detection of recognition result. When result of recognition is found, a measure of recognition result credibility is determined; this determination includes detection of probability of the fact that result of recognition is correct, determination of normalising member and dividing this probability by normalising member. ^ EFFECT: increasing reliability and efficiency of voice recognition. ^ 14 cl, 2 dwg |
