1. An electronic apparatus, comprising:
a memory storing instructions; and
a processor configured to execute the instructions to:
based on a first user speech being received by the electronic apparatus and including a trigger word for activating a speech recognition function of the electronic apparatus, identify a first noise level corresponding to the first user speech received by the electronic apparatus,
identify, from among a plurality of recognition apparatuses that each received the first user speech and have a speech recognition function that is activatable by the trigger word, a first recognition apparatus having a highest first noise level corresponding to the first user speech, wherein the plurality of recognition apparatuses includes the electronic apparatus,
based on the identified first recognition apparatus being the electronic apparatus, turn down a level of sound output by the electronic apparatus and, while the level of sound output by the electronic apparatus is turned down, identify, from among the plurality of recognition apparatuses, a second recognition apparatus having a second noise level corresponding to a second user speech received by each recognition apparatus of the plurality of recognition apparatuses after the first user speech, and which is highest among the plurality of recognition apparatuses, wherein the second user speech includes a control command but does not include the trigger word, and
based on the identified first recognition apparatus being the electronic apparatus and the identified second recognition apparatus not being the electronic apparatus and the control command corresponding to a function of the electronic apparatus, receive information from the identified second recognition apparatus indicating the control command included in the second user speech received by the identified second recognition apparatus and perform the function of the electronic apparatus in accordance with the received information.
