Abstract: PROBLEM TO BE SOLVED: To perform a medley playing without providing musical sound generating devices in two systems by generating the playing sound of a bridge part at the time of the continuous playing of karaoke musics and setting a main musical sound generating means in playing the playing sound of the bridge part to a state suited to the playing of a latter music. SOLUTION: This device is provided with a bridge musical sound generating means (sound source for bridge 19b) for playing a bridge pattern in addition to a main musical sound generating means (a maing sound source 19a, a voice data processing part 20, an effect sound DSP 21a or the like) for playing karaoke musics. This sound source for bridge 19b is an inexpensive sound source capable of simultaneously generating musical sounds of the order of 16 tones with a simple parameter setting. Moreover, the sound source 19b incorporates effect circuits imparting simple reverberation effects with respect to the generated musical sounds. Then, a bridge pattern connecting a preceding music and the latter music smoothly is inserted between these musics and whilst the bridge pattern is played by the sound source device for bridge 19b, parameter settings of the main sound source device 19a and the effect sound DSP 21a are performed.

Abstract: PROBLEM TO BE SOLVED: To provide a voice signal processing device that can convert a singing voice signal of a singer to that of an original singer. SOLUTION: A pitch/sound volume extracting part 31 extracts pitch (frequency) data and sound volume data from a singing voice signal of a singer. An impulse generation part 32 generates a pulse train with an interval based on the pitch data. The pulse train has a wide frequency spectrum near a white noise, but a signal of a tone of an original singer is made by cutting this with formant of an original singer in a filter 33. This formant data is stored as sequence data with music data for KARAOKE playing, read out in parallel with KARAOKE playing, and written in a formant data buffer 36. A signal of a tone of an original singer can be made quite the same as that of a song of a singer by gain-controlling the signal of timre of an original singer with the sound volume data.

Abstract: PROBLEM TO BE SOLVED: To make the tempo of KARAOKE (orchestration without lyrics) follow the singing speed of a singer by judging the singing speed based on melody information supplied by being attached to the playing information of the KARAOKE and the extracted pitch of singing voice and controlling the tempo of playing corresponding to the judged result. SOLUTION: When the singing voice of the singer is inputted from a microphone M, a pitch extraction part 1 extracts the pitch and a voice type recognition part 2 tracks a pitch extracted value for a prescribed period and recognizes whether the pattern of the pitch change of the singing voice is a rising type or a lowering type. A singing speed judgement part 3 compares the pitch specified by the data of a guiding melody and the extracted pitch of the singing voice and judges the singing speed based on the recognized result of the pattern of the guiding melody, the recognized result of the pattern of the singing voice and a pitch compared result. A tempo control part 4 sums up the diagnosed result of the singing speed judgement part 3 in a fixed cycle and controls the tempo to be specified to a sequencer 5 corresponding to the summed-up result.

Abstract: PROBLEM TO BE SOLVED: To reduce the amount of back chorus data by generating the back choruses, in which same chorus phrases are repeated, from common data. SOLUTION: A musical sound reproducing type KARAOKE device 10 includes an LD changer system 11, a monitor 12, a mixing amplifier 13, microphones 14 and speakers 15. A KARAOKE control device 20 is called an integrated type system commander. By partially coupling the device 20 to the device 10, the entire system including the musical sound synthesis/musical sound reproducing functions is integrated and controlled. When musical sounds are generated using a sound source, a back chorus is beforehand digitally sampled and stored. During a reproducing, back choruses are repeatedly selected by the number of ADPCM data as back chorus envents and reproduced. Thus, the back chorus, in which same chorus phrases are repeated, is generated from common data.

Abstract: PROBLEM TO BE SOLVED: To reduce the amount of back chorus data by generating plural back choruses having same chorus phrases but with different sound volumes from common data. SOLUTION: A musical sound reproducing type KARAOKE device 10 includes an LD changer system 11, a monitor 12, a mixing amplifier 13, microphones 14 and speakers 15. A KARAOKE control device 20 is called an integrated type system commander. By partially coupling the device 20 to the device 10, the entire system including musical sound synthesis/musical sound reproducing functions is integrated and controlled. When musical sounds are generated using sound sources, back choruses are beforehand digitally sampled and stored. During a reproducing, these back choruses are automatically volume adjusted as back chorus events and reproduced. Thus, the back choruses, which have same chorus phrases and have the volume that is gradually varied, are generated from common chorus data.

Abstract: PURPOSE: To control each function of KARAOKE according to a position where a KARAOKE singer sings. CONSTITUTION: The coordinate (x) of the position where the KARAOKE singer S stands is detected by singer sensors 11R, 11L. The singer sensors 11 are infrared sensors, which detect the position of the singer by the strength of an infrared ray inputted to both sensors and emitted from the singer. The direction of spot light 14 is adjusted corresponding to the position, and the spot light 14 is set so as to always illuminate the singer even when the singer continues to move. Also, a duet singing signal and a harmony chorus signal outputted in synchronism with KARAOKE singing are positioned at the coordinate decided corresponding to the coordinate (x). The duet singing signal is positioned at a position as shown in D i.e., w-x. The harmony chorus signal C1 is positioned at w-(3/2)x, and the harmony chorus signal C2 at w-x/2.
