ELECTRONIC DEVICE FOR GENERATING PERSONALIZED ASR MODEL AND METHOD FOR OPERATING SAME

An electronic device according to various embodiments of the present invention comprises: a processor; and a memory electrically connected to the processor, wherein the memory can store instructions that allow, when executed, the processor to: store text data generated by recognizing user's voice data using a given automatic speech recognition (ASR) model, as one piece of utterance data together with the voice data, in an utterance data storage functionally connected to the processor; obtain a candidate for replacing an ASR error portion from a plurality of pieces of utterance data stored in the utterance data storage; generate a personalized ASR model by performing deep learning on the ASR model on the basis of the candidate and user's voice data corresponding to the candidate; receive a user's response to the candidate through an input device functionally connected to the processor; and update the ASR model to the personalized ASR model on the basis of the user's response. Various other embodiments are also possible.
