Abstract: An electronic device is disclosed. The electronic device comprises: multiple microphones for receiving audio signals generated by multiple sound sources; a communication unit for communicating with a voice recognition server; and a processor for determining the direction in which each of the multiple sound sources is located with reference to the electronic device, on the basis of the multiple audio signals received through the multiple microphones, determining at least one target sound source among the multiple sound sources on the basis of the duration of the determined direction of each of the sound sources, and controlling the communication unit such that the communication unit transmits, to the voice recognition server, an audio signal of a target sound source from which a predetermined voice is generated among the at least one target sound source.

Abstract: A method and display device for recognizing voice is provided. A method of recognizing voice by a display device for performing an operation according to a control command of a remote control device includes: receiving an audio signal including user voice transmitted from the remote control device, extracting a signal characteristic of the received audio signal, identifying a noise type related to the extracted signal characteristic with reference to signal characteristics for each of a plurality of pre-stored noise types, and outputting guide information corresponding to the identified noise type. Accordingly, the display device provides uttered voice input guidance appropriate for voice recognition to a user so as to enhance voice recognition performance with respect to uttered voice.
