FIELD: acoustics.
SUBSTANCE: invention relates to acoustics, particularly to means of audio data processing received from bone and air conduction microphones. Device contains plurality of audio sensors, first of which is in contact with device user, and second is in contact with air. At that, analysis comprises Fourier transformation, normalization of converted signals to estimate audio signal power and its comparison with threshold value. Then audio signal is output, which is user speech. Device also contains discriminator connected by inputs with microphones outputs, speech detector, speech enhancement circuit, characteristics selection circuit, audio signals correction circuit, transmitting circuit.
EFFECT: audio signals reception is performed, which are analyzed to distinguish audio converter type, which is in contact with user.
