The electronic apparatus includes a memory, a microphone and a processor configured to compare a volume of a voice input through the microphone and a standard voice volume stored in the memory, corresponding to a space in which the electronic apparatus is located, and identify whether to perform a voice recognition on the voice based on the comparison. ## Claims ### Claim 1 An electronic apparatus comprising: a memory; a microphone; and a processor configured to compare a volume of a voice input through the microphone and a standard voice volume stored in the memory, corresponding to a space in which the electronic apparatus is located, and identify whether to perform a voice recognition on the voice based on the comparison. ### Claim 2 (depends on 1) The electronic apparatus as claimed in claim 1, wherein the processor is further configured to, based on the volume of the voice being greater than the standard voice volume, perform the voice recognition on the voice. ### Claim 3 (depends on 1) The electronic apparatus as claimed in claim 1, further comprising: a communication interface, wherein the processor is further configured to, based on another electronic apparatus connected through the communication interface indicating detection of the voice, identify whether to perform the voice recognition based on a predetermined priority order. ### Claim 4 (depends on 3) The electronic apparatus as claimed in claim 3, wherein the processor is further configured to set the predetermined priority order based on at least one from among a placement location of the electronic apparatus and the another electronic apparatus, a recognition result on the voice, and a user manipulation. ### Claim 5 (depends on 3) The electronic apparatus as claimed in claim 3, wherein the processor is further configured to: based on the voice being input through the microphone while in a standby mode, activate the communication interface; based on identifying that the voice recognition on the voice is to be performed, convert a mode of the electronic apparatus into a normal mode in which an entire configuration of the electronic apparatus is activated; and based on identifying that the voice recognition on the voice is not to be performed, inactivate the communication interface. ### Claim 6 (depends on 3) The electronic apparatus as claimed in claim 3, further comprising a sensor configured to sense a size of the space in which the electronic apparatus is located. ### Claim 7 (depends on 3) The electronic apparatus as claimed in claim 3, further comprising a display, wherein the processor is further configured to, based on identifying that the voice recognition on the voice is to be performed, control the display to display a UI screen requesting a confirmation on whether to perform the voice recognition. ### Claim 8 (depends on 7) The electronic apparatus as claimed in claim 7, wherein the processor is further configured to, based on the confirmation not being received within a set time after displaying the UI screen, not perform the voice recognition on the voice, and control the communication interface to transmit information to the another electronic apparatus indicating the confirmation has not been received. ### Claim 9 (depends on 1) The electronic apparatus as claimed in claim 1, further comprising: a sensor; and a communication interface, wherein the processor is further configured to, based on another electronic apparatus connected through the communication interface indicating detection of the voice, identify an utterance direction of a user by using the sensor, and identify whether to perform the voice recognition based on the utterance direction. ### Claim 10 (depends on 1) The electronic apparatus as claimed in claim 1, further comprising a communication interface configured to receive size information from a sensor configured to sense a size of the space in which the electronic apparatus is located. ### Claim 11 (depends on 1) The electronic apparatus as claimed in claim 1, wherein the processor is further configured to, based on identifying the voice as a trigger voice, perform the voice recognition without comparing the voice input through the microphone with the standard voice volume. ### Claim 12 A method for controlling an electronic apparatus, the method comprising: receiving a voice input through a microphone of the electronic apparatus; comparing a volume of the voice and a standard voice volume corresponding to a space in which the electronic apparatus is located; and identifying whether to perform a voice recognition on the voice based on the comparing. ### Claim 13 (depends on 12) The method as claimed in claim 12, further comprising, based on the volume of the voice being greater than the standard voice volume, recognizing the voice. ### Claim 14 (depends on 12) The method as claimed in claim 12, wherein the identifying comprises, based on another electronic apparatus indicating detection of the voice, identifying whether to perform the voice recognition based on a predetermined priority order. ### Claim 15 (depends on 14) The method as claimed in claim 14, further comprising setting the predetermined priority order based on at least one from among a placement location of the electronic apparatus and the another electronic apparatus, a recognition result on the voice, and a user manipulation. ### Claim 16 (depends on 14) The method as claimed in claim 14, further comprising sensing a size of the space in which the electronic apparatus is located. ### Claim 17 (depends on 12) The method as claimed in claim 12, further comprising identifying, based on another electronic apparatus indicating detection of the voice, an utterance direction of a user, wherein the identifying whether to perform the voice recognition is based on the utterance direction. ### Claim 18 (depends on 12) The method as claimed in claim 12, further comprising receiving size information from a sensor configured to sense a size of the space in which the electronic apparatus is located. ### Claim 19 (depends on 12) The method as claimed in claim 12, wherein the identifying comprises performing the voice recognition based on identifying the voice as a trigger voice. ### Claim 20 A non-transitory computer readable recording medium having embodied thereon a program, which when executed by a processor of an electronic apparatus, causes the electronic apparatus to execute a method including: receiving a voice input through a microphone of the electronic apparatus; comparing a volume of the voice and a standard voice volume corresponding to a space in which the electronic apparatus is located; and identifying whether to perform a voice recognition on the voice based on the comparing. ### Claim 21 An electronic apparatus comprising: a memory; an interface; and a processor configured to identify whether to perform a voice recognition on a voice signal received through the interface based on a standard voice level stored in the memory and the voice signal. ### Claim 22 (depends on 21) The electronic apparatus as claimed in claim 21, wherein the processor is further configured to perform the voice recognition on the voice signal based on a level of the voice signal exceeding the standard voice level. ### Claim 23 (depends on 21) The electronic apparatus as claimed in claim 21, wherein the processor is further configured to perform the voice recognition on the voice signal based on a level of the voice signal exceeding the standard voice level and corresponding to a trigger command. ### Claim 24 (depends on 21) The electronic apparatus as claimed in claim 21, wherein the processor is further configured to identify a direction of a user based on the voice signal, and identify whether to perform the voice recognition on the voice signal based on the direction. ### Claim 25 (depends on 21) The electronic apparatus as claimed in claim 21, wherein the processor is further configured to control the interface to notify another electronic apparatus that the voice signal has been received, receive a notification from the other electronic apparatus indicating whether the other electronic apparatus has received the voice signal, and identify whether to perform the voice recognition on the voice signal based on the notification received from the other electronic apparatus. ### Claim 26 (depends on 25) The electronic apparatus as claimed in claim 25, further comprising a display, wherein the processor is further configured to identify whether to perform the voice recognition by controlling a confirmation screen to be displayed on the display based on the voice signal being received, and a confirmation voice signal received through the interface.
