6. The method of claim 1, wherein the receiving of the voice representative information comprises receiving at least one of a data representing raw voice representative information and voice feature information that is extracted from the raw voice representative information.

7. The method of claim 1, wherein the comparing comprises determining whether a similarity between the voice representative information and the reference voice representative information is equal to or greater than a predetermined value.

8. The method of claim 7, wherein, when the similarity is equal to or greater than the predetermined value, the establishing comprises establishing the communication link with the second device, based on the connection information of the second device.

9. The method of claim 7, further comprising, when the similarity is less than the predetermined value, broadcasting the voice representative information received from the second device.

10. The method of claim 1, wherein the connection information of the second device comprises at least one of, ID (identifier) information of the second device, capability information of the second device, state information of the second device, information identifying a communication method preferred by the second device, and service ID information.

11. The method of claim 1, wherein the establishing comprises:

transmitting a connection request to the second device; and

receiving an acceptance message in response to the connection request.

12. The method of claim 1, further comprising:

receiving, from the second device, control information that is extracted from the voice representative information; and

performing a function in response to the control information.

13. The method of claim 12, wherein the control information comprises at least one of a control command to acquire content, a control command to transmit content, a control command to transmit position information, a control command to synchronize a plurality of pieces of data, a control command to switch a mode, and a control command to perform screen-mirroring.

14. The method of claim 1, further comprising, switching a screen lock mode of the first device to a screen unlock mode in response to the comparison.

33. A non-transitory computer-readable recording medium having recorded thereon a program for executing the method of claim 1, by using a computer.

15. A method of communicating between first and second electronic devices, comprising:

in a second device,

acquiring voice representative information;

broadcasting the voice representative information and connection information of the second device indicating characteristics of communication to be used in establishing a communication link with the second device;

receiving a communication connection request from the first device that has received the voice representative information and the connection information, from the second device; and

establishing a communication link with the first device, in response to the connection request and the characteristics of communication.

16. The method of claim 15, wherein the broadcasting comprises periodically broadcasting a sound signal comprising the voice representative information and the connection information of the second device.

17. The method of claim 16, wherein the broadcasting comprises broadcasting the sound signal by inserting the voice representative information and the connection information of the second device into at least one of an inaudible range and an audible range of the sound signal.

18. The method of claim 15, wherein the broadcasting comprises broadcasting the voice representative information and the connection information of the second device via at least one of short range communication and mobile communication.

19. The method of claim 15, wherein the acquiring comprises:

receiving raw voice representative information via a microphone of the second device; and

analyzing the raw voice representative information and extracting voice feature information from the raw voice representative information.

20. The method of claim 15, wherein the broadcasting comprises broadcasting at least one of raw voice representative information and voice feature information extracted from the raw voice.

21. The method of claim 15, wherein the receiving comprises receiving the connection request from the first device in response to a result of comparing, by the first device, the voice representative information with reference voice representative information that is stored in the first device.

22. The method of claim 15, further comprising:

extracting control information from the voice representative information; and

transmitting the control information to the first device.

23. The method of claim 22, further comprising performing a function in response to the control information via the communication link.

24. The method of claim 23, wherein the performing of the function comprises transmitting content to the first device via the communication link, wherein the content is displayed on a screen of the second device when the voice representative information is obtained.

25. A first device that communicates with a second device, the first device comprising:
