Problems solved by technology

Thus, to its disadvantages, the device would result in noticeable monotonous performance when used for a long melody or in a dissonance due to exclusion of harmony with chords when a chord is generated in addition to a melody tone.

Embodiment Construction

FIG. 1 is a block diagram of a voice processor embodying the present invention. This system is designed to pitch convert a voice input through a microphone 1 with a pitch conversion LSI 5 and thereafter put it out as mixed with the original voice by a mixer 6.

The main part of the system is made up of digital circuits. A voice input through the microphone 1 is amplified by an amplifier 2 and then converted into a digital signal by an A / D converter circuit 3. The digital signal converted by the A / D converter circuit 3 is fed to a pitch detector circuit 4, the pitch conversion LSI 5, and the mixer 6. The pitch detector circuit 4 and pitch conversion LSI 5 are connected to a CPU 10. Others, which include a ROM 11, a RAM 12, an external memory 13, a panel switch 14, and a MIDI input / output connectors 15,16, are also connected to the CPU 10. The ROM 11 has stored programs for processing input digital data. The external memory 13 is given by a floppy disk unit or a `karaoke` system (the sy...

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.

Description

BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a voice processor which is capable of producing sound effects by pitch conversion of voices.2. Description of the Prior ArtBy now, there have come into practical use electronic musical instruments so arranged that when a monotone melody is played, additional harmonic tones are automatically generated for simplifying the playing thereof. Also, there have been devices practically available which are adapted to convert the pitch of a voice to be generated for its output to thereby increase special impression of tones as well as entertaining features thereof.However, in such electronic musical instruments adapted to generate additional tones in connection with a monotone melody as above, only a separate tone generator for additional tones is provided in addition to a tone generator (tone waveform shaping circuit) for melodies.Moreover, a conventional device adapted to automatically make pitch conversion...
