Abstract

Provided are a display apparatus, a control method thereof, a server, and a control method thereof. The display apparatus includes: a processor which processes a signal; a display which displays an image based on the processed signal; a command receiver which receives a voice command; a communicator which communicates with a first server; a storage; and a controller which receives, from the first server, a voice recognition command list comprising a voice recognition command and control command information corresponding to the voice recognition command, and stores the received voice recognition command list in the storage, the voice recognition command being among user's voice commands which have successfully been recognized a predetermined number of times or more, determines whether the voice command corresponds to the voice recognition command included in the voice recognition command list, and if so, controls the processor to operate based on the control command information, and if not, transmits the voice command to the first server, receives corresponding control command information from the first server, and controls the processor to operate based on the received control command information.

First claim

What is claimed is:

1. A display apparatus comprising:
a signal receiver which receives a signal;
a display panel which displays an image based on the received signal.
a command receiver which receives a voice command from a user;
a communicator which communicates with a first server; and
a controller which:
receives, from the first server, a first voice command list comprising a plurality of voice commands each of which has been collected from a plurality of display apparatuses and successfully recognized a predetermined number of times or more and corresponding control commands,
stores the received first voice command list,
receives a first voice command from the user, and
in response to determining that the received first voice command is not comprised in the first voice command list, transmits the received first voice command to the first server, and receives a second voice command list updated by adding the transmitted first voice command and a corresponding control command to the first voice command list from the first server, and

updates the stored first voice command list into the received second voice command list.

2. The display apparatus according to claim 1 , wherein the controller determines whether the received voice command is comprised in the first voice command list based on a determined relevance between the received voice command and the voice command comprised in the first voice command list.

3. The display apparatus according to claim 1 , wherein, in response to a predetermined time elapsing after the received voice command is transmitted to the first server, the controller operates based on the voice command comprised in the first voice command list.

4. The display apparatus according to claim 3 , wherein, in response to the predetermined time elapsing after the received voice command is transmitted to the first server, the controller notifies the user of a content of the voice command comprised in the stored first voice command list in advance, and determines whether to operate based on the voice command according to a response by the user to the notifying.

5. The display apparatus according to claim 1 , wherein if the received voice command is newly recognized for a user, the controller transmits, to the first server, the recognized voice command and control command corresponding to the recognized voice command.

6. The display apparatus according to claim 1 , wherein the controller transmits, to a second server, the received voice command, receives, from the second server, a text to which the transmitted voice command has been converted, and transmits the received text to the first server.

7. A control method of a display apparatus, the control method comprising:
receiving, from a first server, a first voice command list comprising a plurality of voice commands each of which has been collected from a plurality of display apparatuses and successfully recognized a predetermined number of times or more and control commands corresponding to the voice command;
storing the received first voice command list;
receiving a first voice command from a user;
in response to determining that the received first voice command is not comprised in the first voice command list, transmitting the received first voice command to the first server, and receiving a second voice command list updated by adding the transmitted first voice command and a corresponding control command to the first voice command list from the first server; and
updating the stored first voice command list into the received second voice command list.

8. The control method according to claim 7 , wherein the determining whether the received voice command is comprised in the first voice command list comprises determining whether the received voice command corresponds to the voice command comprised in the first voice command list based on a determined relevance between the received voice command and the voice command comprised in the first voice command list.

9. The control method according to claim 7 , further comprising operating based on the voice command comprised in the first voice command list in response to a predetermined time elapsing after the received voice command is transmitted to the first server.

10. The control method according to claim 9 , wherein the operating based on the voice recognition command comprised in the first voice command list in response to the predetermined time elapsing comprises notifying the user of a content of the voice command comprised in the first voice command list in advance and determining whether to operate based on the voice command according to a response by the user to the notifying.

11. The control method according to claim 7 , further comprising, if the received voice command is newly recognized for a user, transmitting, to the first server, the recognized voice command, and control command corresponding to the recognized voice command.

12. The control method according to claim 7 , further comprising:
transmitting, to a second server, the received voice command;
receiving, from the second server, a text to which the transmitted voice command has been converted, from the second server, and
transmitting the received text to the first server.

13. A server which analyzes a user's voice command to a display apparatus, the server comprising:
a communicator which communicates with a plurality of display apparatuses;
a storage which stores information regarding a plurality of voice commands and corresponding control commands; and
a controller which:
transmits a first voice command list comprising the plurality of voice commands each of which has been collected from a plurality of display apparatuses and successfully recognized a predetermined number of times or more and the corresponding control commands to one of the plurality of display apparatuses, and
in response to receiving a first voice command which is transmitted from the one of the plurality of display apparatuses and is not comprised in the first voice command list, generates a second voice command list updated by adding the received first voice command and a corresponding control command to the first voice command list, and transmits the generated second voice command list to the one of the plurality of display apparatuses, so that the one of the plurality of display apparatuses can update stored first voice command list into the received second voice command list.

14. A control method of a server which analyzes a user's voice command to a display apparatus, the control method comprising:
communicating with one of a plurality of display apparatuses;
transmitting a first voice command list comprising a plurality of voice commands each of which has been collected from a plurality of display apparatuses and successfully recognized a predetermined number of times or more and corresponding control commands to the one of the plurality of display apparatuses;
in response to receiving a first voice command which is transmitted from the one of the plurality of display apparatuses and is not comprised in the first voice command list, generating a second voice command list updated by adding the received first voice command and a corresponding control command to the first voice command list; and
transmitting the generated second voice command list to the one of the plurality of display apparatuses, so that the one of the plurality of display apparatuses can update stored first voice command list into the received second voice command list.
