VOICE RECOGNITION DEVICE, VOICE RECOGNITION METHOD, AND VOICE RECOGNITION PROGRAM

摘要

PROBLEM TO BE SOLVED: To accurately recognize a voice from an arbitrary direction without accompanying any delay due to the estimation of a sound source direction.SOLUTION: A voice recognition device 1 includes: a directivity control part 12 for acquiring each of voice streams from a plurality of directions; a first voice recognition processing part 13 for executing voice recognition to each of the voice streams from the plurality of directions acquired by the directivity control part 12; and a voice source direction determination part 14 for, when a voice recognition result satisfying the predetermined reference of reliability is obtained by the first voice recognition processing part 13, determining a direction corresponding to the voice stream from which the voice recognition result has been obtained as a sound source direction.SELECTED DRAWING: Figure 1
