An apparatus comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
• receive an indication of a trigger;
• receive an audio input in response to an audio verification signal outputted via an audio device based on the indication of the trigger, wherein the audio input comprises:
• a voice command, and
• an audio signal;
• verify the voice command based on a comparison of the audio verification signal and the audio signal;
• and
• cause, based on the verifying the voice command, execution of an operation associated with the voice command.
