6. The electronic apparatus of claim 4 , wherein the preset event comprises at least one of an event of initializing the electronic apparatus and an event having no response to a request for the at least one first sound information.
7. The electronic apparatus of claim 1 , wherein the memory is configured to store latency information of the at least one home appliance in each of a plurality of regions, and
wherein the processor is further configured to execute the at least one instruction to:
identify latency information of each of the at least one first sound information, and
identify the position of the user based on the identified latency information and the latency information stored in the memory.
8. The electronic apparatus of claim 1 , further comprising:
a driver,
wherein the processor is further configured to execute the at least one instruction to control the driver to move the electronic apparatus to the position of the user.
9. The electronic apparatus of claim 8 , further comprising:
a camera,
wherein the processor is further configured to execute the at least one instruction to:
based on the electronic apparatus moving to the position of the user, capture an image through the camera, and
identify the user based on the image.
10. The electronic apparatus of claim 9 , wherein the memory is further configured to store user information in which face information of each of a plurality of users and voice information of each of the plurality of users are mapped, and
wherein the processor is further configured to execute the at least one instruction to:
obtain face information corresponding to the preset user voice based on the user information, and
identify the user corresponding to the face information from the image.
11. The electronic apparatus of claim 10 , further comprising:
a speaker,
wherein the processor is further configured to execute the at least one instruction to output the preset sound through the speaker based on the face information corresponding to the preset user voice not being obtained based on the user information, or based on the user corresponding to the face information not being identified from the image.
12. A method of controlling an electronic apparatus, comprising:
receiving a preset user voice of a user;
requesting at least one first sound information from at least one home appliance, each of the at least one first sound information corresponding to the preset user voice received at each of the at least one home appliance;
receiving the at least one first sound information from the at least one home appliance; and
identifying a position of the user based on the preset user voice and the at least one first sound information.
13. The method of claim 12 , wherein the requesting the at least one first sound information comprises:
based on the preset user voice being received, transmitting time information about when the preset user voice is received to the at least one home appliance, and
wherein the at least one first sound information received from the at least on home appliance corresponds to the time information.
14. The method of claim 13 , wherein the identifying the position of the user comprises:
identifying position information of the at least one home appliance by determining latency information of each of the at least one first sound information received from each of the at least one home appliance, and
identifying the position of the user based on the position information of the at least one home appliance.
15. The method of claim 12 , wherein the identifying the position of the user comprises:
identifying the position of the user based on a position information of the at least one home appliance, the preset user voice, and the at least one first sound information.
16. The method of claim 14 , wherein the identifying the position information of the at least one home appliance comprises:
