Abstract
The voice processor includes a microphone for a device for inputting a voice signal, a device for inputting chord information from an electronic musical instrument or the like, a converter for converting the pitch of the voice signal into a specified pitch according to the chord information, a mixer for mixing the input voice signal and a pitch-converted voice signal, and a loudspeaker for outputting the mixed signal. The pitch of the input voice signal is converted into such one as will be consonant with the chord information or as will coincide therewith and thereafter the pitch converted signal will be output along with the input voice signal.
