Abstract

A display apparatus and a voice controlling method thereof are provided. The voice controlling method includes receiving a voice of a user; converting the voice into text; and sequentially changing and applying a plurality of different determination criteria to the text until a control operation corresponding to the text is determined; and performing the determined control operation to control the display apparatus.

First claim

What is claimed is:

1. A voice controlling method of a display apparatus, the voice controlling method comprising:
receiving a voice of a user;
converting the voice into text;
determining a control operation corresponding to the text by sequentially applying a plurality of different determination criteria to the text; and
performing the control operation to control the display apparatus,
wherein the plurality of different determination criteria comprise criteria of whether the text corresponds to a title of an object displayed on a screen of the display apparatus, and whether the text corresponds to a stored command, a criterion of whether the text corresponds to a title of an object displayed on a screen of the display apparatus being applied before a criterion of whether the text corresponds to a stored command, and
wherein the determining the control operation comprises:
determining whether the text corresponds to the title of the object;
in response to determining that the text corresponds to the title of the object, determining the control operation based on the object;
in response to determining that the text does not correspond to the title of the object, determining whether the text corresponds to the stored command; and
in response to determining that the text corresponds to the stored command, determining an operation corresponding to the stored command as the control operation.

2. The voice controlling method of claim 1 , wherein the determining the control operation based on the object comprises:
determining an operation corresponding to the object as the control operation.

3. The voice controlling method of claim 1 , wherein the determining whether the text corresponds to the title of the object comprises, in response to a part of the title of the object being displayed and the text corresponding to at least a portion of the displayed part of the object, determining that the text corresponds to the title of the object.

4. The voice controlling method of claim 1 , wherein the determining whether the text corresponds to the title of the object comprises, in response to only a part of one word included in the title of the object being displayed and the text corresponding to the whole one word, determining that the text corresponds to the title of the object.

5. The voice controlling method of claim 1 , wherein the object comprises at least one of a content title, an image title, a text icon, a menu name, and a number that are displayed on the screen.

6. The voice controlling method of claim 1 , wherein the stored command comprises at least one of a command for controlling power of the display apparatus, a command for controlling a channel of the display apparatus, and a command for controlling a volume of the display apparatus.

7. The voice controlling method of claim 1 , further comprising:
in response to determining that the text does not correspond to the stored command, determining whether a meaning of the text is analyzable; and
in response to determining that the meaning of the text is analyzable, analyzing the meaning of the text and determining an operation of displaying a response message corresponding to a result of the analyzing as the control command.

8. The voice controlling method of claim 7 , further comprising:
in response to determining that the meaning of the text is not analyzable, determining an operation of a search using the text as a keyword, as the control operation.

9. The method of claim 1 , wherein the plurality of different determination criteria further comprise criteria of whether the text is grammatically analyzable, and whether the text refers to a keyword.

10. A display apparatus comprising:
a voice input circuit configured to receive a voice of a user;
a voice converter configured to convert the voice into text;
a storage configured to store a plurality of determination criteria that are different from one another; and
a controller configured to determine a control operation corresponding to the text by sequentially applying a plurality of different determination criteria to the text, and perform the control operation,
wherein the plurality of different determination criteria comprise criteria of whether the text corresponds to a title of an object displayed on a screen of the display apparatus, and whether the text corresponds to a stored command, a criterion of whether the text corresponds to a title of an object displayed on a screen of the display apparatus being applied before a criterion of whether the text corresponds to a stored command, and
wherein the controller is further configured to determine whether the text corresponds to the title of the object, determine the control operation based on the object in response to determining that the text corresponds to the title of the object, determine whether the text corresponds to the stored command in response to determining that the text does not correspond to the title of the object, and determine an operation corresponding to the stored command as the control operation in response to determining that the text corresponds to the stored command.

11. The display apparatus of claim 10 , wherein the controller is further configured to, in response to determining that the text corresponds to the title of the object, determine an operation corresponding to the object as the control operation.

12. The display apparatus of claim 10 , wherein the controller is further configured to, in response to only a part of the title of the object being displayed and determining that the text corresponds to the part of the title of the object being displayed, determine that the text corresponds to the title of the object.

13. The display apparatus of claim 10 , wherein the controller is further configured to, in response to only a part of one word included in the title of the object being displayed and determining that the text corresponds to the whole one word, determine that the text corresponds to the title of the object.

14. The display apparatus of claim 10 , wherein the object comprises at least one of a content title, an image title, a text icon, a menu name, and a number that are displayed on the screen.

15. The display apparatus of claim 10 , wherein the stored command comprises at least one of a command for controlling power of the display apparatus, a command for controlling a channel of the display apparatus, and a command for controlling a volume of the display apparatus.

16. The display apparatus of claim 10 , wherein the controller is further configured to, in response to determining that the text does not correspond to the stored command, determine whether a meaning of the text is analyzable, and, in response to determining that the meaning of the text is analyzable, analyze the meaning of the text and determine an operation of displaying a response message corresponding to the analysis result, as the control operation.

17. The display apparatus of claim 16 , wherein the controller is further configured to, in response to determining that the meaning of the text is not analyzable, determine an operation of a search using the text as a keyword, as the control operation.
