To memorize. Normally, the system control section 7 reproduces the performance music in accordance with the registration order of the music number data stored in the performance music information storage section 15, but in order to simplify the description, nothing is registered before the performance music is registered. It is assumed that the karaoke is scored along with the reproduction of the performance music.

The system control unit 7 stores the performance music information storage unit 1
No. 5 is constantly searched, and it is determined whether there is a music piece to be reproduced and whether or not to perform karaoke scoring. In this case, since the music number data to be subjected to karaoke scoring is registered, Then, the operation immediately proceeds to the operation for reproducing the music piece. The system control unit 7 searches the karaoke music data stored in the auxiliary storage device 6 for karaoke music data corresponding to the music number based on the music number data stored in the performance music information storage unit 15 and compresses the data. The stored karaoke music data is decompressed into karaoke accompaniment data, lyric data and back chorus data, temporarily stored in the auxiliary storage device 6, and then only a part of the data is transferred to the main storage device 14. To remember. Then, the system control unit 7 downloads the font data required for displaying the lyrics to the main storage device 14 and immediately starts playing the karaoke music.

The system control unit 7 controls the MIDI sound source unit 8 based on the karaoke accompaniment data and the back chorus data when performing the karaoke music, thereby reproducing the performance signal necessary for the performance of the music, and The signal is output to the mixer / amplifier unit 10. Then, the mixer / amplifier unit 10 combines the performance signal and the singer's voice signal input from the microphone 4 and outputs the synthesized signal to the speaker 11 and the synthesized signal processing unit 24, so that the performance music and the singing voice are made audible. Reproduce.

Further, the system control section 7 controls the external video reproducing apparatus 2 based on the genre information in the lyrics display control data to output a background video corresponding to the genre of the music to the superimposing section 9. At the same time, when the lyrics image is output to the superimposing section 9 based on the font index and the color change information in the lyrics display control data, the superimposing section 9 combines the background image and the character image to display the image on the image display device. 3 for playback.

The system control unit 7 outputs a control signal for performing karaoke scoring to the music reference signal creating unit 16 and evaluates the karaoke singing by controlling the MIDI sound source unit 8 so that the karaoke accompaniment data in the karaoke accompaniment data is The guide melody signal is output to the music reference signal creation unit 16. When receiving the control signal for performing the karaoke scoring, the music reference signal creating unit 16 and the control signal indicating that, and a signal indicating the start and end of a partial phrase such as rust of the karaoke music (hereinafter referred to as a “phrase identification signal”) ) Is output to the control unit 21, and based on the guide melody signal, a music reference signal that is a singing reference of the karaoke music is created and output to the signal comparison unit 19. Also, the signal comparison unit 19
, A singer's voice signal is input from the microphone 4 at the same time.

When the music reference signal and the singer's voice signal are input, the signal comparison unit 19 outputs a comparison signal of the signals, for example, a difference signal between the music reference signal and the voice signal, to the scoring unit 20. . When receiving the control signal and the phrase identification signal for performing the karaoke scoring, the control unit 21 recognizes the start and end ranges of the karaoke scoring for each partial phrase such as the chorus of the karaoke music, and determines the scoring start and the scoring end. The control signal is output to the scoring unit 20 and a recording start command is output to the composite signal processing unit 24.

When receiving the control signal from the control unit 21, the scoring unit 20 outputs the evaluation result of the karaoke singing to the control unit 21 for each partial phrase based on the comparison signal from the signal comparison unit 19. Temporarily stores the karaoke singing evaluation result from the scoring unit 20 in the built-in RAM of the control unit 21 and outputs the partial phrase to the score display unit for display.

The combined signal processing unit 24 includes a control unit 21
Receives a recording start command from the mixer / amplifier unit 10
The synthesized signal input from the A / D converter is AD-converted and stored in the synthesized signal storage unit 25 as synthesized signal data in association with the partial phrase. Reproduction operation: After the scoring and recording operation for each partial phrase is completed as described above, when the operator operates the input unit 23 to instruct a desired reproduction operation, the control unit 21 analyzes the reproduction instruction command. To reproduce the specified partial phrase.

For example, when the operator instructs the reproduction of the partial phrase having the highest evaluation, the control unit 21 recognizes the highest-evaluated partial phrase from the karaoke song evaluation result temporarily stored in the built-in RAM. And the synthesized signal processing unit 2
A command to reproduce the partial phrase is issued to 4 and the score is displayed on the score display section 22. Synthesized signal processing unit 24
Receives a playback instruction for a partial phrase, DA-converts the combined signal data stored in association with the partial phrase, and outputs the resultant signal to the mixer / amplifier unit 10.
Will play the highest rated partial phrase. However, the reproduction of the partial phrases is performed by operating the input unit 23 by the operator to specify a partial phrase having the lowest evaluation or a desired partial phrase, or to automatically reproduce the highest / lowest phrases before recording. In the mode, immediately after the end of the recording operation, the partial phrases having the highest and lowest evaluations are automatically reproduced together with the display of the evaluation points.

[0036]

As described above, according to the karaoke system provided with the karaoke singing evaluation apparatus according to the present invention, the karaoke singing evaluation is performed for each part of the karaoke song such as the phrase at the beginning of singing and the phrase in the chorus part. To display the evaluation score, and simultaneously play the performance music and the singer's singing voice, so that the singer can understand the quality of his singing for each phrase,
It is possible to improve one's singing ability by practicing the parts with low evaluations.
