Provided is a home appliance and a speech recognition server system, in which a plurality of speech recognition home electronics may perform a command intended by a user without conflicting with one another using artificial intelligence with respect to a speech command of the user and a method for controlling such a home appliance and a speech recognition server system. The present disclosure determines whether a first group to which a control target device belongs is identical to a second group to which a speech recognition device belongs when the control target device is different from the speech recognition device. Then, when the first group is different from the second group, the present disclosure controls an operation of the control target device based on the control command of the user. Accordingly, the user may control the control target device disposed in a space different from another space in which the speech recognition device is disposed.
