Abstract
To provide a speaker position detection method capable of significantly calculating a speaker position.SOLUTION: A speaker position detection method includes the steps of: acquiring voices of a speaker by a microphone; calculating direction information of the speaker based on the acquired voices of the speaker; acquiring a face image of the speaker from an image, which is acquired by a camera, on the basis of the direction information; and detecting position information including height direction of the speaker based on the acquired face image of the speaker.SELECTED DRAWING: Figure 4
