Method for analyzing user utterance based on utterance cache and electronic device supporting the same

An electronic device comprising:

• a communication interface;
• memory storing instructions;
• and
• at least one processor operatively connected to the communication interface and the memory,
• wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
• identify whether first text data corresponding to an input utterance corresponds to text data stored in the memory;
• based on identifying that the first text data corresponding to the input utterance corresponds to the text data stored in the memory, transmit, through the communication interface, the first text data corresponding to the input utterance to an external server;
• identify whether an operation corresponding to the input utterance is executable by the electronic device;
• based on identifying that the operation is executable by the electronic device, execute the operation;
• and
• based on identifying that the operation is not to be executable by the electronic device, transmit the first text data corresponding to the input utterance to the external server through the communication interface and add the first text data corresponding to the input utterance to the memory,
• wherein the electronic device is a client device that is operatively connected with the external server.
