description A voice processing device includes plural microphones 22 disposed in a vehicle, a voice source direction determination portion 16 determining a direction of a voice source by handling a sound reception signal as a spherical wave in a case where the voice source serving as a source of a voice included in the sound reception signal obtained by each of the plural microphones is disposed at a near field, the voice source direction determination portion determining the direction of the voice source by handling the sound reception signal as a plane wave in a case where the voice source is disposed at the far field, and a beamforming processing portion 12 performing beamforming so as to suppress a sound arriving from a direction range other than a direction range including the direction of the voice source.
