1. A control device comprising:
an external device interface configured to transmit and receive signals to and from a display device;
a user input interface configured to receive a user input;
a power supply;
an audio output device including a speaker configured to receive power supplied from the power supply; and
a controller configured to:
based on a first voice input being received through the user input interface in a standby mode in which the display device is deactivated, check a first command corresponding to the first voice input;
output a response to the first command through the audio output device based on the first command not being a command related to image output;
based on the first command being the command related to image output:
transmit a signal to the display device through the external device interface to release the standby mode, the signal being for activating the display device;
cut off power supplied from the power supply to the audio output device to deactivate the audio output device, based on the standby mode being released;
based on a second voice input being received through the user input interface while the standby mode is released, check a second command corresponding to the second voice input; and
transmit an audio signal to the display device through the external device interface, the audio signal corresponding to a response to the second command.
 
5. A system comprising:
a display device; and
a control device,
wherein the display device comprises a display panel and a main audio output device,
wherein the control device comprises a sub audio output device, and
wherein the control device is configured to:
based on a first voice input being received in a standby mode in which the display device is deactivated, check a first command corresponding to the first voice input;
output a response to the first command through the sub audio output device based on the first command not being a command related to image output;
based on the first command being the command related to image output:
transmit a signal to the display device to release the standby mode, the signal being for activating the display device;
cut off power supplied to the sub audio output device to deactivate the sub audio output device, based on the standby mode being released;
based on a second voice input being received through the user input interface while the standby mode is released, check a second command corresponding to the second voice input; and
transmit an audio signal to the display device, the audio signal corresponding to a response to the second command,
wherein the display device is configured to output audio through the main audio output device, the audio corresponding to the audio signal received from the control device.
