A voice processing device includes plural microphones arranged so as to correspond to a plurality of positions. The voice processing device includes at least one memory that stores instructions and voice signals from the plural microphones, and a processor. The voice signals collected by the plural microphones, respectively, during a prescribed period before a present time, are repeatedly stored in the at least one memory as buffered voice signals. The processor detects whether a prescribed word is uttered by a speaker based on the voice signals collected by the plural microphones, determines a microphone corresponding to the speaker by referring to the buffered voice signals, and suppresses the voice signals collected by the plural microphones other than the microphone corresponding to the speaker.
