FIELD: acoustics.
SUBSTANCE: invention relates to means of audio signal generation. Obtaining a first audio signal, which speech user, using the sensor being in contact with the user. Second audio signal is obtained using an air duct sensor, the second audio signal is user's speech which includes noise from the medium surrounding the user. Speech periods are detected in the first audio signal. Speech enhancement algorithm is applied to the second audio signal to reduce noise in the second audio signal, the algorithm of improving speech uses detected periods of speech in the first audio signal. Corrected first audio signal using noise of the second audio signal for generating output audio signal, which is user's speech.
EFFECT: technical result consists in reduction of noise components in speech audio signal.
