The present invention relates to a voice conversation analysis apparatus and a method therefor and, more specifically, to: a voice conversation analysis apparatus categorizing voices generated during a voice conversation so as to predict required functions and further analyzing the voices so as to provide proper functions; and a method therefor. In addition, disclosed are: an artificial intelligence (AI) system for simulating the functions of recognition, decision-making, and the like of the human brain by using a machine learning algorithm; and an application thereof. According to one embodiment, disclosed in an electronic device control method for performing an operation through a suitable operating mode by using an AI learning model so as to analyze a voice conversation, comprising the steps of: receiving a voice and acquiring information on the voice; acquiring category information on the voice on the basis of the information on the voice so as to determine at least one operating mode corresponding to the category information; and performing an operation related to the operating mode by using an AI model corresponding to the determined operating mode.
