Abstract

A voice recognition apparatus is provided. The voice recognition apparatus comprises: a voice receiver which receives a user'"'"'s voice signal; a first voice recognition engine which receives the voice signal and performs a voice recognition process; a communication unit which receives the voice signal and transmits the voice signal to an external second voice recognition engine; and a controller which transmits the voice signal received through the voice receiver to at least one of the first voice recognition engine and the communication unit.

Claims

1. A voice recognition apparatus comprising:

a voice receiver configured to receive a voice signal;

a first voice recognition engine configured to receive the voice signal and perform a voice recognition process;

a communication unit configured to receive the voice signal and transmit the voice signal to a second voice recognition engine; and

a controller configured to transmit the voice signal received through the voice receiver to at least one from among the first voice recognition engine and the communication unit.

2. The voice recognition apparatus according to claim 1, wherein the first voice recognition engine comprises an embedded engine which recognizes only preset words, and the second voice recognition engine comprises a server engine which recognizes a plurality of consecutive words.

3. The voice recognition apparatus according to claim 1, further comprising an input unit which receives an input signal through a remote control device, wherein the remote control device comprises at least one voice recognition engine-selecting button to select the voice recognition engine.

4. The voice recognition apparatus according to claim 3, wherein if time during which the at least one voice recognition engine-selecting button is selected is a predetermined time or more, the controller transmits the voice signal to one from among the first voice recognition engine and the second voice recognition engine, and if the selected time is less than the predetermined time, transmits the voice signal to the other one from among the first voice recognition engine and the second voice recognition engine.

5. The voice recognition apparatus according to claim 3, wherein the at least one voice recognition engine-selecting button of the remote control device comprises a plurality of buttons corresponding to the first voice recognition engine and the second voice recognition engine, and if an input signal corresponding to one from among the plurality of buttons is received, the controller transmits the voice signal to the voice recognition engine corresponding to the button.

6. The voice recognition apparatus according to claim 1, wherein if the voice signal is received through the voice receiver, the controller determines which one from among the first voice recognition engine and the second voice recognition engine will perform the voice recognition process, based on whether the received voice signal comprises a preset word.

7. The voice recognition apparatus according to claim 6, wherein the received voice signal is transmitted to the first voice recognition engine and the second voice recognition engine, respectively, and the controller determines whether the voice signal comprises the preset word, based on a voice recognition result provided by the first voice recognition engine.

8. The voice recognition apparatus according to claim 1, wherein the controller determines whether a beginning of the voice signal comprises a preset word.

9. The voice recognition apparatus according to claim 1, wherein the voice recognition apparatus is implemented as a display apparatus comprising a display unit, and the controller displays on the display unit a user interface (UI) comprising information on a voice recognition engine that processes the voice signal.

21. The voice recognition apparatus of claim 1, wherein the voice signal is a user'"'"'s voice signal.

22. The voice recognition apparatus of claim 1, wherein the second voice recognition engine is external to the voice recognition apparatus.

10. A voice recognition method of a voice recognition apparatus comprising:

Receiving, at the voice recognition apparatus, a voice signal;

deciding at least one from among a first voice recognition engine and a second voice recognition engine, which will process the received voice signal; and

transmitting the voice signal to at least one from among the first voice recognition engine and the second voice recognition engine based on a decision result.

11. The voice recognition method according to claim 10, wherein the first voice recognition engine is comprised in the voice recognition apparatus and the first voice recognition engine comprises an embedded engine which recognizes only preset words, and the second voice recognition engine is provided external to the voice recognition apparatus and the second voice recognition engine comprises a server engine which recognizes a plurality of consecutive words.

12. The voice recognition method according to claim 11, further comprising receiving an input signal through a remote control device, wherein the remote control device comprises at least one voice recognition engine-selecting button to select the voice recognition engine.

13. The voice recognition method according to claim 12, wherein the deciding comprises determining one from among the first voice recognition engine and the second voice recognition engine which processes the voice signal if time during which the at least one voice recognition engine-selecting button is selected is a predetermined time or more, and determining the other one from among the first voice recognition engine and the second voice recognition engine which processes the voice signal if the selected time is less than the predetermined time.

14. The voice recognition method according to claim 12, wherein the at least one voice recognition engine-selecting button of the remote control device comprises a plurality of buttons corresponding to the first voice recognition engine and the second voice recognition engine, respectively, and the deciding comprises determining which one from among the first voice recognition engine and the second voice recognition engine processes the voice signal corresponding to the at least one voice recognition engine-selecting button if an input signal corresponding to one from among the plurality of buttons is received.

15. The voice recognition method according to claim 10, further comprising determining whether the received voice signal comprises a preset word, wherein the deciding comprises determining which one from among the first voice recognition engine and the second voice recognition engine performs a voice recognition process, based on the determination result.

16. The voice recognition method according to claim 15, wherein the received voice signal is transmitted to the first voice recognition engine and the second voice recognition engine, and the determining comprises determining whether the voice signal comprises the preset word, based on the voice recognition result provided by the first voice recognition engine.

17. The voice recognition method according to claim 16, wherein the determining comprises determining whether a beginning of the voice signal comprises the preset word.

18. The voice recognition method according to claim 10, wherein the voice recognition apparatus is implemented as a display apparatus comprising a display unit to display an image thereon, further comprising:

displaying on the display unit a user interface (UI) comprising information on the voice recognition engine which processes the voice signal.

23. The voice recognition method according to claim 10, wherein the voice signal is a user'"'"'s voice signal.

24. The voice recognition method according to claim 10, wherein the first voice recognition engine is comprised in the voice recognition apparatus and the second voice recognition engine is provided external to the voice recognition apparatus.

19. A voice recognition apparatus comprising:

a voice receiver configured to receive a voice signal;

a first voice recognition engine configured to receive the voice signal and perform a voice recognition process;

a communication unit configured to receive the voice signal and transmit the voice signal to at least one from among a plurality of voice recognition engines; and

a controller configured to transmit the voice signal received through the voice receiver to at least one from among the first voice recognition engine and the at least one from among the plurality of voice recognition engines.

20. A voice recognition method of a voice recognition apparatus comprising:
