Sound generator direction presumption device, sound generator direction presumption manner, and robot device

摘要

P To easily and comprehensively identify a sound source by using voice and information collected by a sensor in order to improve noise resistance, without specifying a sound source direction only by sound effect, and to attain the sound source direction estimation capable of reducing cost with a simple configuration and for the purpose of estimating the direction in which the sound source exists. PSOLUTION: In a system of the invention, the direction of the sound source is estimated not only by collecting sound information from the sound source by a microphone and but by collecting information for specifying the sound source direction by an infra-red sensor, an ultra-sonic sensor and a switch etc., and identification accuracy of the sound source direction is improved.
