Voice recognition service operating method and electronic device supporting same

An electronic device comprising:

• communication circuitry;
• a processor;
• and
• memory,
• wherein the memory stores instructions causing the processor to:
• receive a first user input;
• receive, from an intelligent server, a path rule, wherein the intelligent server selects the path rule from a set of predefined path rules stored in the intelligent server or generates the path rule based on a user request;
• determine an action sequence based on the first user input, wherein the action sequence comprises a plurality of actions;
• determine whether there is a learned training database related to the determined action sequence;
• perform an action using the determined action sequence based on determination that there is no the learned training database related to the determined action sequence, wherein the action is performed based on the path rule;
• determine whether the determined action sequence is a second user input for user training in case that the second user input is a user's voice input providing a negative reaction or repetitive reactions;
• display a user interface for updating domain information and state information based on determination that the action sequence is the second user input for the user training, and receive a third user input through the user interface;
• track the third user input and execution information of the electronic device to sequentially arrange the domain information and the state information based on determination that the action sequence is the input for the user training, wherein the domain information is identified for an application selected through the user interface and the state information is identified for a screen operated by the application;
• update the domain information and the state information according to the tracked user input and execution of the electronic device;
• when a user training action is completed, transmit, to the learned training database, the updated domain and the state information and display a feedback screen indicating completion of update of the domain information and the state information;
• and
• update the learned training database according to the updated domain information and the state information.
