PROBLEM TO BE SOLVED: To attain effective noise elimination as balancing both of a computation load and sound quality.SOLUTION: A voice processing device is configured to: acquire a voice signal of a plurality of channels including a first channel and a second channel; detect a phase difference between the channels; generate a first prediction voice signal for replacing the voice signal in a noise immixture segment, using the voice signal of the first channel in at least one of a segment in front of a noise immixture segment in the acquired voice signal and a segment at the back thereof, and replace the voice signal of the first channel in the noise immixture segment with the first prediction voice signal; and next, generate a second prediction voice signal by correcting the first prediction voice signal on the basis of the phase difference, and replace the voice signal of the second channel in the noise immixture segment with the second prediction voice signal.SELECTED DRAWING: Figure 8 |
