ELECTRONIC DEVICE AND SYSTEM WHICH PROVIDES SERVICE BASED ON VOICE RECOGNITION

摘要

A memory included in a system according to an embodiment may be configured to store an automatic speech recognition (ASR) module and a natural language understanding (NLU) module, and the memory is configured to store instructions that, when executed, cause the processor to receive a wake-up utterance for calling a voice-based intelligent assistance service, through the microphone, to receive a first user utterance through the microphone after the wake-up utterance, to process the first user utterance, using the NLU module, to generate a first response based on the processed first user utterance, to receive a second user utterance through the microphone during a time interval selected after receiving the wake-up utterance, to extract a text for the second user utterance, using the ASR module, to process the second user utterance to generate a second response, using the NLU module when a selected word or phrase is included in the text for the second user utterance, and when the selected word or phrase is not included in the text for the second user utterance, to do not generate a response to the second user utterance.
