An electronic device supporting a speech recognition service, the electronic device comprising:

• a communication module configured to communicate with at least one external device;
• a microphone configured to receive a voice input according to a user utterance;
• a first wake-up recognition module configured to activate a function of the speech recognition service;
• a second wake-up recognition module configured to activate a recording function for the user utterance;
• a memory configured to store at least one trigger information associated with activation of the function of the speech recognition service or the recording function;
• and
• a processor electrically connected to the communication module, the microphone, the first wake-up recognition module, the second wake-up recognition module, and the memory,
• wherein the processor is configured to:
• receive a first user utterance through the microphone;
• recognize the first user utterance based on at least one of the first wake-up recognition module or the second wake-up recognition module;
• when the recognized first user utterance includes specified at least one first trigger information, record at least part of the first user utterance by activating the recording function, transmit recorded data through the communication module to a first external device supporting an operation of the speech recognition service, and receive at least one of second user utterance information, which is predicted to occur at a time after the function of the speech recognition service is activated by the first wake-up recognition module, or at least one response information associated with the second user utterance from the first external device through the communication module.
