extracting the domain information and the intent information based on the identified latest utterance related information and the second input utterance; and
obtaining and outputting a response result based on the extracted domain information and intent information.
3 . The method according to claim 2 , further comprising:
updating the utterance-related information using the extracted domain information and the intent information.
4 . The method according to claim 2 , wherein, based on the second input utterance including name information of a target device, transmitting the second input utterance to the target device.
5 . An electronic device comprising:

store utterance-related information comprising any one of a time stamp representing a processing time of a past input utterance, information related to an utterance task, an utterance history, domain information, and intent information in the memory;
based on receiving a first signal requesting utterance-related information from external electronic device that is connected to a same network and receives a first utterance,
identify latest utterance-related information based on a time stamp included in the utterance-related information:
extract the utterance-related information based on the identified latest utterance related information;
control the communication circuit to transmit the extracted utterance-related information to the external electronic device
receiving a second signal requesting processing of the first utterance from the external electronic device based on the external electronic device determining from the utterance-related information transmitted by the electronic device that the first utterance is a continuation utterance of the past input utterance;
obtaining a response result for the first utterance based on domain information and intent information; and
controlling the communication circuit to transmit the response result to the external electronic device for output by the external electronic device.
6 . The electronic device according to claim 5 , wherein the at least one processor is configured to:
receive a second input utterance;
determine whether domain information and intent information are able to be extracted by analyzing the second input utterance;
based on at least one of the domain information and the intent information not being extracted as a result of the determination, broadcast a signal requesting utterance related information to one or more external devices;
when the utterance related information prestored in the at least one external device is received, identify latest utterance related information based on a time stamp included in the utterance related information received from the at least one external device;
extract the domain information and the intent information based on the identified latest utterance related information and the input utterance; and
obtain and output a response result based on the extracted domain information and intent information.
7 . The electronic device according to claim 6 , wherein the at least one processor is configured to update the utterance related information using the extracted domain information and the intent information.
8 . The electronic device according to claim 6 , wherein the at least one processor is configured to control the electronic device to, based on the second input utterance including name information of a target device, control the communication circuit to transmit the second input utterance to the target device.
9 . A non-transitory computer-readable medium storing instructions which, when executed by at least one processor, cause an electronic device to perform operations comprising:
pre-storing utterance-related information comprising any one of a time stamp representing a processing time of a past input utterance, information related to an utterance task, an utterance history, domain information, and intent information;
receiving a first signal requesting utterance-related information from an external electronic device that is connected to a same network as the electronic device and that receives a first utterance;
identifying latest utterance-related information based on a time stamp included in the utterance-related information;
extracting the utterance-related information based on the identified latest utterance-related information;
transmitting the extracted utterance-related information to the external electronic device;
receiving a second signal requesting processing of the first utterance from the external electronic device based on the external electronic device determining from the utterance-related information transmitted by the electronic device that the first utterance is a continuation utterance of the past input utterance;
obtaining a response result for the first utterance based on domain information and intent information; and
transmitting the response result to the external electronic device for output by the external electronic device.
10 . The non-transitory computer-readable storage medium according to claim 9 , storing instructions which, when executed by the at least one processor, cause the electronic device to perform operations comprising:
