Abstract: An electronic device and method are disclosed herein. The electronic device includes a network interface and processor. The processor implements the method, including receiving a voice input through a network interface as transmitted from a first external device, including a request to execute a function using at least one application which is not indicated in the voice input, extracting a first text from the voice input by executing automatic speech recognition (ASR), when the at least one application is identified based on the first text, transmitting, through the network interface to the first external device, second data associated with the identified at least one application for display by the first external device, and when the at least one application is not identified based at least in part on the first text, reattempting identification of the at least one application by executing natural language understanding (NLU) on the first text.

Abstract: Disclosed are an apparatus and a method for tracking locations of a plurality of sound sources. According to the apparatus and the method, a task for searching sound source candidates is repeated at respective predetermined frames of microphone signals to collect sound source candidates, and only the collected sound source candidates are verified through beamforming, thereby more rapidly and accurately tracking the plurality of sound sources in spite of using a small number of microphones.

Abstract: A directional sound source filtering apparatus using a microphone array and a control method thereof are provided. The directional sound source filtering apparatus using a microphone array includes an image detector to detect images in a destination area, a sound collector located by the microphone array in which microphones are arranged to detect sound sources together with the images detected by the image detector. The apparatus includes a controller to precalculate time delay values of sound sources within the images in order to extract sound sources within the image from the sound sources detected by the sound collector, and perform beamforming through the calculated time delay values. Sound source signals only within images may be selectively amplified using beamformers.

Abstract: An apparatus for detecting endpoints of sound signals when sound sources vocalized from a remote site are processed even if a plurality of speakers exists and an interference sound being input from a direction different from a direction of one speaker, and a method thereof, wherein in an environment in which a plurality of sound sources exists, the existence and the length of the sound source being input according to each direction is determined and the endpoint is found, thereby improving the performance of the post-processing, and speech being input from a direction other than a direction of speech from a speaker vocalized at a remote area from a sound source collecting unit is distinguished while the speech from the speaker is being recorded, thereby enabling a remote sound source recognition without restriction on the installation region of a microphone.

Abstract: A sound source signal processing apparatus including a first sound source detection unit having at least one microphone to detect a sound source signal, a second sound source detection unit having at least one microphone to detect the sound source signal, the second sound source detection unit being spaced apart from the first sound source detection unit, and a beamforming unit to beamform the sound source signal detected by the first sound source detection unit and the second sound source detection unit. At least one microphone is further provided in addition to the microphone array, and position information of the microphones and sound source information are used, thereby improving beamforming performance of the sound source signal. Also, the number and size of microphone arrays is reduced through further provision of the at least one microphone, thereby improving spatial utilization.
