2. The display apparatus according to claim 1, wherein a plurality of the voice acquiring units are provided, and if a voice input to at least one of the plurality of voice acquiring units is detected, the controller receives a voice signal from the voice acquiring unit to which the voice input is detected.

3. The display apparatus according to claim 2, wherein the display unit displays a user interface (UI) showing the voice acquiring unit connected to the display apparatus.

4. The display apparatus according to claim 2, wherein the voice acquiring unit comprises at least one of a built-in microphone provided in the display apparatus, a first external microphone provided in the at least one of the plurality of external apparatuses, and a second external microphone provided in an apparatus different from the display apparatus and the plurality of external apparatuses.

5. The display apparatus according to claim 1, wherein the external apparatus comprises at least one application which manages the candidate instruction words.

6. The display apparatus according to claim 1, wherein the display apparatus comprises at least one native application which manages the candidate instruction words.

7. The display apparatus according to claim 1, further comprising a storage unit configured to store the received candidate instruction words, wherein the voice recognition engine recognizes the voice by using the received candidate instruction words.

8. The display apparatus according to claim 2, wherein if a wakeup keyword to one of the plurality of voice acquiring units is detected, the controller enables the voice acquiring unit by which the wakeup keyword is detected, and receives a voice signal from the enabled voice acquiring unit.

9. The display apparatus according to claim 2, wherein if a trigger signal is input by a manipulation of a predetermined button provided in one of the plurality of voice acquiring units, the controller enables the voice acquiring unit by which the trigger signal is input, and receives a voice signal from the enabled voice acquiring unit.

10. The display apparatus according to claim 1, wherein the controller controls the display unit to display voice recognition results for the voice signal and candidate instruction words according to the voice recognition results.

11. The display apparatus according to claim 10, wherein the display unit further displays information on an application managing the candidate instruction words.

12. The display apparatus according to claim 1, wherein the voice recognition engine recognizes the voice by deciding an instruction word that is identical to or similar to the received voice signal, among the received candidate instruction words.

13. A voice acquiring apparatus comprising:

a communication unit configured to communicate with a display apparatus having a voice recognition function;

a voice acquiring unit configured to receive a user'"'"'s voice;

a voice converter configured to convert the received voice into an electric voice signal; and

a controller configured to control the communication unit to transmit the converted voice signal and candidate instruction words to the display apparatus to recognize the voice signal.

14. The voice acquiring apparatus according to claim 13, further comprising at least one application which manages the candidate instruction words.

15. A voice recognition method of a display apparatus, the method comprising:

receiving a voice signal from a voice acquiring unit;

receiving candidate instruction words from at least one of a plurality of external apparatuses to recognize the received voice signal; and
