9. A controlling method of an electronic apparatus configured to provide a voice recognition function, the method comprising:
storing location information of the electronic apparatus and other electronic apparatuses;
based on a trigger voice being identified through a microphone that detects sound using a plurality of channels, identifying an utterance direction of the trigger voice;
sharing information regarding the identified utterance direction with the other electronic apparatuses;
estimating an utterance location by calculating a contact point based on information regarding the utterance direction received from the other electronic apparatuses, the identified utterance direction, the location information of the electronic apparatus and the location information of the other electronic apparatuses;
activating a voice recognition function of the electronic apparatus based on the stored location information and the estimated utterance location;
based on a voice recognition function being activated, performing a voice recognition function regarding a user's uttered voice received through the microphone;
identifying a sound pressure of the trigger voice;
sharing information regarding the identified sound pressure together with information regarding the identified utterance direction;
preferentially comparing distances between the plurality of electronic apparatuses and an utterance location;
based on a difference in distance being less than a predetermined value, determining a voice recognition apparatus of which input sound pressure is largest among a plurality of electronic apparatuses based on sound pressure information of the plurality of electronic apparatuses; and
based on the electronic apparatus being the voice recognition apparatus, activating a voice recognition of the electronic apparatus.
