         8 . The control method according to  claim 7 , wherein the determining whether the received voice command corresponds to the voice recognition command comprised in the stored voice recognition command list comprises determining whether the received voice command corresponds to the voice recognition command comprised in the stored voice recognition command list based on a determined relevance between the received voice command and the voice recognition command. 
     
     
         9 . The control method according to  claim 7 , further comprising operating based on the voice recognition command comprised in the stored voice recognition command list in response to a predetermined time elapsing after the received voice command is transmitted to the first server. 
     
     
         10 .
