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.

Electronic device and method for processing audio signal by electronic device

An electronic device and a control method therefor are provided. The electronic device comprises: a plurality of microphones for receiving audio signals in which voice signals are included; a communicator for receiving state information according to information about a connection with the electronic device; and a processor for determining the noise environment around the electronic device based on one or more of audio amplitude information that is received by the plurality of microphones and that is output by an external device, and state information of the external device, and for processing the voice signal based on the determined noise environment so as to perform voice recognition.

Electronic device for voice recognition, and control method therefor

An electronic apparatus is provided. The electronic apparatus according to an embodiment includes an audio input unit configured to receive sound sources from different positions and generate a plurality of voice signals, a pre-processor configured to perform pre-processing of the plurality of voice signals, and a voice recognition unit configured to perform voice recognition using the plurality of voice signals pre-processed by the pre-processor, and in response to a predetermined trigger being detected as a result of the voice recognition, generate trigger information, wherein the pre-processor is further configured to receive feedback on the trigger information generated by the voice recognition unit, change a pre-processing method according to the trigger information, process the plurality of voice signals using the changed pre-processing method, and generate enhanced voice signals.

Electronic apparatus for performing pre-processing based on a speech recognition result, speech recognition method thereof, and non-transitory computer readable recording medium

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.

Method and display device for recognizing voice

A content processing device is provided. The content processing device includes a receiver configured to receive a content, an audio processor configured to extract an audio signal by decoding audio data included in the content, a processor configured to determine a characteristic section in the audio signal based on a ratio of music information of the audio signal, and detect a segment corresponding to the characteristic section in the audio signal; and a communicator configured to transmit the segment to a music recognition server, and a size of the segment is determined variably within a threshold range.

Content processing device and method for transmitting segment of variable size, and computer-readable recording medium

Described are systems and methods performed by computer to reduce crosstalk produced by loudspeakers when rendering binaural sound that is emitted from the loudspeakers into a room. The room may have sound-reflecting surfaces that reflect some of the sound produced by the loudspeakers. To reduce crosstalk, a room model stored by the computer, is accessed. The room model models at least sound reflected by one or more of the physical surfaces. The room model is used to calculate a model of an audio channel from the loudspeakers to a listener. The model of the audio channel models sound transmission from the loudspeakers to the listener. The computer uses the model of the audio channel to cancel crosstalk from the loudspeakers when rendering the binaural sound.
