The present invention relates to a method and an apparatus for recognizing a sound source. According to the sound source recognition method of the present invention, an acoustic signal is detected by four acoustic sensors arranged in a rectangular shape when viewed in a horizontal direction, an acoustic arrival time is measured, six Interactive Time Differences (ITDs) are generated on the basis of the difference between the acoustic arrival times of the respective sound sensors, and the position of the sound source is estimated on the basis of the six ITDs. In addition, features of the sound source are extracted and classified by using a sum signal from the four acoustic sensors to determine the type of the sound source.

    La présente invention concerne un procédé et un appareil pour reconnaître une source sonore. Selon le procédé de reconnaissance de source sonore de la présente invention, un signal acoustique est détecté par quatre capteurs acoustiques disposés selon une forme rectangulaire lorsqu'ils sont vus dans une direction horizontale, un temps d'arrivée acoustique est mesuré, six différences temporelles interactives (ITD) sont générées sur la base de la différence entre les temps d'arrivée acoustique des capteurs sonores respectifs, et la position de la source sonore est estimée sur la base des six ITD. De plus, des caractéristiques de la source sonore sont extraites et classées en utilisant un signal de somme provenant des quatre capteurs acoustiques pour déterminer le type de la source sonore.

    본 발명은 음원 인식 방법 및 장치에 관한 것이다. 본 발명의 음원 인식 방법에 따르면 수평 방향으로 보았을 때 직사각형의 형상으로 배열된 4개의 음향센서로부터 음향신호를 검출하고, 음향 도착시간을 측정하고, 각 음향센서들 간의 음향 도착시간 차이에 기초하여 6개의 ITD(interaural time difference)를 생성하며, 상기 6개의 ITD에 기초하여 음원의 위치를 추정한다. 아울러, 4개의 음향센서로부터의 합산 신호를 이용하여 음원의 특징을 추출하고 분류하여 음원의 종류를 인식한다.
