PROBLEM TO BE SOLVED: To attain noise reduction in consideration of a frequency fluctuation of a noise component due to temperature change and secular change, etc.SOLUTION: A voice processing device includes: voice input means; drive means; a memory for storing a noise profile to be generated from a noise spectrum obtained by converting the sound signal of noise related to the drive means into a frequency area; correction means for correcting the noise profile with the use of auxiliary data indicating a fluctuation due to the disturbance of noise related to the drive means; and voice processing means for reducing noise related to the drive means from a voice signal to be input by the voice input means with the use of the noise profile corrected by the correction means.SELECTED DRAWING: Figure 1 |
