1. An electronic device comprising:
- a display;
an audio input processor configured to;
receive an audio signal, andtransfer a first driving signal to an audio recognition processor when a frequency of the audio signal corresponds to a preset frequency band,the audio recognition processor configured to;
perform a first voice recognition on the audio signal in response to the first driving signal, the first voice recognition including a speaker recognition,recognize a voice trigger of a registered speaker in the audio signal, andtransfer a second driving signal to a main processor based on a result of the first voice recognition, andthe main processor configured to;
perform a second voice recognition based on at least one of a voice signal by the first voice recognition and the audio signal, in response to the second driving signal, the second voice recognition including a command recognition,execute an application associated with a voice command based on a result of the second voice recognition, andmaintain an off state of the display during the second voice recognition, and turn on the display to display an execution screen of the application in response to successful recognition of the second voice.

Abstract
Provided is an electronic device that includes a first processor for receiving an audio signal, performing first voice recognition on the audio signal, and transferring a driving signal to a second processor based on a result of the first voice recognition. The second processor performs second voice recognition based on a voice signal by the first voice recognition or the audio signal, in response to the driving signal.
