An electronic device includes a memory storing first vector information obtained from a pre-registered user voice, and a processor configured to obtain, based on a user voice being received, second vector information of a first filtered user voice by inputting the received user voice and the first vector information stored in the memory to a trained first neural network model, obtain second filtered user voice information by inputting the second vector information of the first filtered user voice and the received user voice to a trained second neural network model, and perform voice recognition based on the second filtered user voice information.
