FIELD: acoustics.
SUBSTANCE: claimed group of inventions relates to voice-activated sound conversion for headsets using the representation of signals of the microphone in the frequency domain, potentially especially suitable for applications related to protection of hearing organs. The method for voice-activated conversion includes determining the voice power parameter based on the representation of the voice signal incoming from the voice microphone in the frequency domain. The method also includes determining the external power parameter based on the representation of at least one external signal incoming from at least one external microphone spaced from the voice microphone in the frequency domain. The method also includes starting the conversion of the audio signal based on the voice signal in response to the comparison of the power parameters and the threshold value. In a headset containing a controller, a method can be applied to determine whether to activate or deactivate conversion, transmission, or both, of the audio signal to another apparatus.
EFFECT: by eliminating the requirement for carrying additional communication equipment, the weight of the communication equipment carried by the user can be reduced, thus increasing the range of movement and/or relocation of the user; the provided accurate detection of the voice of the user in a noisy environment can improve communication with other people; the accurate voice detection can also contribute to improved power conservation of the battery and an increase in the time between charges due to deactivation of certain functions when the user is not talking.
