Abstract
A method, apparatus, and computer program product for protecting electronic devices from obstructed voice commands. The method includes receiving, by an electronic device, an audio command and identifying the audio command as a sensitive command. The electronic device performs a spectral analysis of the sensitive command. The spectral analysis is processed, via a learning model, to determine whether the sensitive command is obstructed. The method determines, in response to the sensitive command being obstructed, that the sensitive command is unauthorized and initiates at least one remediation action.
