Abstract
(EN)
The present technology relates to a specific-sound detection apparatus and method, and a program, that make it possible to improve specific-sound detection performance. This specific-sound detection apparatus is provided with a specific-sound detection unit that detects a specific sound on the basis of a plurality of audio signals picked up and obtained by a plurality of microphones disposed on a wearable device. In addition, the plurality of microphones comprise at least two microphones which are equidistant from the sound source of the specific sound, and one microphone which is arranged at a prescribed position. The present technology is applicable to headphones.

La présente technologie concerne un appareil et un procédé de détection de son spécifique, et un programme, qui permettent d'améliorer les performances de détection de son spécifique. Cet appareil de détection de son spécifique est pourvu d'une unité de détection de son spécifique qui détecte un son spécifique sur la base d'une pluralité de signaux audio capturés et obtenus par une pluralité de microphones disposés sur un dispositif habitronique. De plus, la pluralité de microphones comprend au moins deux microphones qui sont équidistants de la source sonore du son spécifique, et un microphone qui est agencé à un emplacement prescrit. La présente technologie est applicable aux casques d'écoute.
