Abstract

Provided are an image display apparatus and a method of controlling the same. The image display apparatus enabling voice recognition includes: a first voice inputter which receives a user-side audio signal; an audio outputter which outputs an audio signal processed by the image display apparatus; a first voice recognizer which recognizes the user-side audio signal received through the first voice inputter; and a controller which decreases a volume of the audio signal output through the audio outputter to a predetermined level if a voice recognition start command is received.

Claims

1. A display apparatus comprising:

a display;

a communication unit to communicate with an external device;

an audio output unit to output an audio signal; and

a controller, in response to receiving a control signal from the external device while displaying an image corresponding to a content on the display and outputting an audio corresponding to the content through the audio output unit, to activate a speech recognition and control an output volume of the audio output unit, and in response to deactivating the speech recognition, to restore the output volume of the audio output unit to a volume level set before the speech recognition started,

wherein the external device includes a remote controller, the remote controller comprising;

a user interface for generating the control signal for the display apparatus to activate the speech recognition;

an audio receiver to receive an audio input; and

a communicator to communicate with the display apparatus, the communicator transmitting signals corresponding to the audio input received via the audio receiver to the display apparatus of which the speech recognition is activated, and

wherein the speech recognition is capable of being activated while the content is being viewed.

2. The display apparatus according to claim 1, wherein the controller controls the output volume by decreasing the output volume to a predetermined level while continuing to display the content being viewed.

3. The display apparatus according to claim 1, wherein the controller controls the audio output unit to decrease the output volume to a predetermined level.

4. The display apparatus according to claim 3, wherein the content being viewed comprises a broadcast program provided independently from the speech recognition.

5. The display apparatus according to claim 3, wherein the controller deactivates the speech recognition when an audio input for speech recognition is not received during a predefined time after activating the speech recognition, and restores an output volume to the volume level set before the speech recognition started.

6. The display apparatus according to claim 3, wherein the controller outputs a message requesting an audio input for speech recognition when an audio input is not received during a predefined time after activating the speech recognition.

7. The display apparatus according to claim 6, wherein the message output by the controller comprises a message image displayed on the display.

8. The display apparatus according to claim 6, wherein the message output by the controller comprises an audio message output by the audio output unit.

9. The display apparatus according to claim 3, further comprising:

a broadcast signal receiver to receive a broadcast signal including a video signal and an audio signal;

a signal processor to process the received broadcast signal and display as the broadcast program.

10. The display apparatus according to claim 1, wherein the controller deactivates the speech recognition when an audio input for speech recognition is not received during a predefined time after activating the speech recognition, and restores an output volume to the volume level set before the speech recognition started.

11. The display apparatus according to claim 1, wherein the controller deactivates the speech recognition when an audio input for speech recognition is not received during a predefined time after activating the speech recognition from the external device, and restores an output volume to the volume level set before the speech recognition started.

12. The display apparatus according to claim 1, wherein the remote controller transmits data corresponding to the audio input received by the audio receiver to the display apparatus through the communicator.

13. The display apparatus according to claim 12, further comprising a speech recognition unit to analyze the audio input received from the remote controller.
