FIELD: computer technology.
SUBSTANCE: invention relates to the field of computer technology for processing audio data. An audio signal generated near an acoustic device by a human user or other electronic device is fixed by an acoustic device; the acoustic device receives a processing filter indicating a predetermined signal correction pattern, which is an excluded part that was excluded from the original speech fragment containing an activation word and intended for replaying by another electronic device; the processing filter is used by the acoustic device to determine the presence of the predetermined signal correction pattern in the audio signal and to determine that the audio signal was formed by another electronic device, if there is the predetermined signal correction pattern in the audio signal.
EFFECT: increase in the accuracy of recognition by the virtual assistant application of adapted content containing the speech fragment of the activation word.
