  The output terminal of the video mixer 5 is connected to two CRTs 8 and 9 provided for karaoke singers and listeners. The output port of the microcomputer 2 is connected to the disc player 10, and the output terminal of the disc player 10 is connected to the video mixer 5. The disc player 10 has a built-in video disc such as a CD-ROM, and the video data output as the background video to the CRTs 8 and 9 while the karaoke song is being reproduced is compressed by the MPEG standard. It is remembered.
[0012]
  The hard disk 3 contains karaoke musical sound data (MIDI signal) given to the MIDI sound source 4 via the microcomputer 2 and the lyrics of the karaoke songs displayed on the CRTs 8 and 9 in a state synthesized with the background video in the video mixer 5. Image data (hereinafter referred to as lyrics data) is stored.
  Further, as shown in FIG. 3, the hard disk (storage means) 3 is used for the progress of karaoke songs such as start of performance, during prelude, singing, rust, interlude, end of singing, after performance, end of performance, etc. The data of the performance attribute signal indicating the performance state that changes along with it is stored in a format as shown in accordance with the elapsed time from the performance start time of the karaoke song, for example.
[0013]
  The microphone 11 outputs the input voice of the singer to the audio mixer 6 as an audio signal converted into an electric signal, and the audio mixer 6 is set with the audio signal and the musical tone signal of the karaoke song reproduced in the MIDI sound source 4. The sound is mixed (mixed) based on the sound volume balance and output to the speaker 7.
  The audio signal of the microphone 11 is supplied to the input terminal of the scoring device (karaoke scoring device) 12 via the audio mixer 6, and the input / output terminal of the scoring device 12 is the input / output port of the microcomputer 2. It is connected to the.

The above constitutes a karaoke apparatus.
[0014]
  FIG. 1 shows a detailed configuration of the scoring device 12 in function blocks. In FIG. 1, the scoring device 12 is configured around a microcomputer 13. In addition, regarding the inside of the microcomputer 13, functions realized mainly by software are shown in blocks.
  The operation buttons (evaluation level setting means, scoring part designation means, change part designation means) 14 are operated by the user so as to make a specific part for specifying the karaoke song scoring, and to make the scoring sweet or hard. The operation level is provided to the input processing section 15 of the microcomputer 13. The input processing unit 15 writes the operation signal given by the operation button 14 in the operation information storage unit 16a of the memory 16 composed of a RAM or the like, and stores information related to the setting.
[0015]
  The timing attribute processing unit (scoring means) 17 of the microcomputer 13 is provided with the performance attribute signal described above. The timing generation processing unit 17 outputs a timing signal with an appropriate period to the arithmetic processing unit 18 by counting the number of timer interrupts generated by the system timer of the microcomputer 13, for example. The cycle and output timing of the timing signal are determined by reading the setting information stored in the motion information storage unit 16a and referring to the performance attribute signal.
[0016]
  The arithmetic processing unit (scoring means) 18 is supplied with an audio signal and a scoring reference signal, and the arithmetic processing unit 18 outputs an audio signal in synchronization with the timing signal supplied from the timing generation processing unit 17. Sampling and pitch of audio signal relative to scoring reference signalDepartureThe voice timing deviation is calculated, and the singer's singing is scored according to the magnitude of the deviation.
  Specifically, the arithmetic processing unit 18 responds to how many cents the pitch of the sampled audio signal is deviated from the interval or utterance timing defined in the scoring reference signal, or according to the time lag of the utterance timing. Then, scoring is performed by deducting from a predetermined origin (for example, 100 points). The arithmetic processing unit 18 sequentially stores the information on the scoring performed for each input of the timing signal in the scoring information storage unit 16 b of the memory 16.
[0017]
  The performance attribute signal is also provided to the display processing unit 19, and when the performance attribute signal indicates “end of performance”, the display processing unit 19 displays the scoring information stored in the scoring information storage unit 16b. The scoring result is written in the scoring result storage unit 16c, and the scoring result is displayed on the display 20 composed of, for example, a 7-segment LED. The above constitutes the karaoke scoring device 12.
[0018]
  Next, the operation of this embodiment will be described with reference to FIGS. The user of the karaoke device performs necessary settings by operating the operation buttons 14 of the scoring device 12. As shown in FIG. 4, there are three setting items in this case: “evaluation type”, “evaluation level”, and “partial designation”.
  There are two types of “evaluation type”: “overall evaluation” and “partial evaluation”. The former is selected when the singing performed by the singer on the karaoke song is performed, and the latter is the above-mentioned singing. Select to evaluate only a specific part of.
[0019]
  “Evaluation level” is the severity of singing, and there are, for example, “sweet”, “normal”, and “spicy” expressing this in easy-to-understand words. The default evaluation level is set to “Normal”, but “Sweet” is selected when scoring at a more gradual evaluation level, and “Spicy” is selected when scoring at a stricter evaluation level. To do.
  “Partial designation” designates a specific part of the singing, and there are, for example, three types of “singing”, “rust”, and “singing end”. When “Evaluation Type” is set to “Overall Evaluation” and “Evaluation Level” is set to “Sweet” or “Spicy”, and any of the above three types is specified, the specified specification For the part, scoring is performed at the evaluation level set in the “evaluation level”, and for the other parts, scoring is performed at the default evaluation level (normal).
  In addition, when “partial evaluation” is set in “evaluation type”, only the specified specific part is scored at the evaluation level set in “evaluation level”, and for other parts, scoring is performed. Not done. In the “partial designation”, it is possible to designate two of the above three types in combination.
[0020]
  Next, the user operates various keys on the operation panel 1 or the remote controller 1a to input a number (song number) assigned to the karaoke song selected by the singer. When the song number is input, the microcomputer 2 serving as the performance attribute signal output means reads the musical tone and lyric data and performance attribute signal data corresponding to the musical number from the hard disk 3 and outputs the musical tone data to the MIDI sound source 4. The performance attribute signal is output to the scoring device 12 and the lyrics data is output to the video mixer 5 in synchronization with the musical sound data. The MIDI sound source 4 outputs musical tones corresponding to the timbres of various musical instruments in accordance with the given MIDI signals, and gives the musical tone signals of karaoke songs to the audio mixer 6.
[0021]
  Further, the microcomputer 2 outputs a selection signal to the disc player 10 so that appropriate video data corresponding to the music number is output. Then, the disc player 10 reads the video data corresponding to the selection signal from the video disc, converts it into an NTSC signal, and outputs it to the video mixer 5. The video mixer 5 synthesizes the lyric data given by the microcomputer 2 with the video signal outputted by the disc player 10 and outputs them to the CRTs 8 and 9. The CRTs 8 and 9 display the given video data on the screen.
  On the other hand, the musical tone signal of the karaoke song given to the audio mixer 6 is amplified according to the set volume level and given to the speaker 7 to be reproduced as a karaoke song. A singer listens to the karaoke song and sings a song to input sound into the microphone 11 while viewing the lyrics display of the CRT 8. The sound input to the microphone 11 is converted into an electric signal, amplified according to the volume level set in the audio mixer 6, and output from the speaker 7 together with the karaoke song.
[0022]
  FIG. 5 shows a flowchart of control contents in the microcomputer 13 of the scoring device 12. First, the input processing unit 15 of the microcomputer 13 is a code indicating "start of performance" as a performance attribute signal in a state where the loop of the determination steps S1 and S2 of "Is the start of performance?" And "Is there a button operation?" Is output and whether or not the operation button 14 has been operated.
  When the operation button 14 is operated as described above to set the karaoke scoring device 12 before the start of the performance of the karaoke song, the input processing unit 15 determines “YES” in step S 2, “ The process proceeds to “Store” processing step S3. In the processing step S3, the input processing unit 15 uses the information (“evaluation type”, “evaluation level”, “partial evaluation”, etc.) set by the operation button 14 as operation information in the operation information storage unit 16a of the memory 16. Write and store. Then, the process proceeds to step S1.
[0023]
  As described above, when the performance of the karaoke song is started and the code indicating “start of performance” is output as the performance attribute signal from the microcomputer 2, the input processing unit 15 determines “YES” in step S1. Then, the process proceeds to the determination step S4 of "Whole evaluation?"
  In determination step S4, the timing generation processing unit 17 refers to the operation information storage unit 16a to determine whether or not the selected evaluation type is “overall evaluation”. If “overall evaluation” is selected and the timing generation processing unit 17 determines “YES”, the process proceeds to determination step S5 of “partial designation?”, And if “partial evaluation” is selected and it is determined “NO”. Then, the process proceeds to the determination step S14 of “is it a specific part?”.
[0024]
  In the determination step S5, the timing generation processing unit 17 similarly refers to the operation information storage unit 16a to determine whether or not the partial designation has been made. The process proceeds to determination step S12 of “?”, And if it is determined “NO” because the partial designation is not made, the process proceeds to determination step S6 of “evaluation level“ normal ”?”.
  In the determination step S12, the timing generation processing unit 17 refers to the performance attribute signal of the karaoke song and determines whether or not the current karaoke song progress state is in the part designated as the specific part. If “NO” is determined instead, the process proceeds to processing step S7 of “generation of basic timing”, and if “YES” is determined in the specific portion, the process proceeds to processing step S13 of “timing generation according to evaluation level”.
[0025]
  In the determination step S14, the timing generation processing unit 17 performs the same determination as in step S12. If “YES” is determined, the process proceeds to step S13. If “NO” is determined, the process proceeds to the determination step S9.
  In the determination step S6, the timing generation processing unit 17 determines whether or not the evaluation level set with reference to the operation information storage unit 16a is “normal”, and the set evaluation level is “normal”. If “YES” is determined, the process proceeds to step S7, and if the evaluation level is “sweet” or “spicy” and “NO” is determined, the process proceeds to processing step S13.
[0026]
  In processing step S 7, the timing generation processing unit 17 generates a timing signal having a basic period corresponding to the evaluation level “normal” and outputs the timing signal to the arithmetic processing unit 18. In processing step S 13, the timing generation processing unit 17 generates a timing signal having a period corresponding to the evaluation level “sweet”, “spicy”, or “normal”, and outputs the timing signal to the arithmetic processing unit 18.
  Here, the timing signal corresponding to “sweet” or “spicy” has a period longer or shorter than the basic period of the timing signal corresponding to “normal”. If it is 5 seconds, the period of the timing signal corresponding to “sweet” is set to 1 second, and the period of the timing signal corresponding to “spicy” is set to 0.1 second. When the processes of steps S7 and S13 are completed, the process proceeds to process step S8 of “calculation process”.
[0027]
  In the processing step S8, the arithmetic processing unit 18 samples the audio signal in synchronization with the timing signal given from the timing generation processing unit 17, and with respect to the pitch and utterance timing defined in the scoring reference signal, Scoring is performed by deducting from a predetermined origin (for example, 100 points) depending on how many cents the pitch is shifted and how many seconds the utterance timing is shifted. Then, the arithmetic processing unit 18 sequentially writes and stores the scoring information in the scoring information storage unit 16 b of the memory 16. Next, the process proceeds to a determination step S9 of "Is the performance finished?"
[0028]
  In determination step S9, the arithmetic processing unit 18 refers to the performance attribute signal to determine whether or not the performance of the karaoke song has ended. If a signal indicating “end of performance” has not been output and it is determined “NO”, the process proceeds to step S4, and the above procedure is repeated to continue scoring. If a signal indicating “end of performance” is output and “YES” is determined, the process proceeds to “Scoring of scoring information” processing step S10.
  In processing step S10, the display processing unit 19 writes a scoring result obtained by tabulating the scoring information written in the scoring information storage unit 16b into the scoring result storage unit 16c. Then, the process proceeds to processing step S11 of “display of the scoring result”, and the display processing unit 19 ends the processing when the scoring result written in the scoring result storage unit 16c is output and displayed on the display unit 20. To do.
[0029]
  Regarding the above processing, there are various scoring modes depending on the selection by the operation button 14. For each mode, the flow of processing from the start to the end of the performance is as follows.
  (1) Overall evaluation / no partial designation / evaluation level “normal” (or no designation) Steps S4 → S5 → S6 → S7 → S8 → S9 are repeated. In this case, the operation is exactly the same as that of a conventional karaoke scoring device, and the entire karaoke piece is scored according to a timing signal of a basic period (for example, 0.5 seconds).
  (2) Overall evaluation / no partial designation / evaluation level “sweet” or “spicy”
Steps S4 → S5 → S6 → S13 → S8 → S9 are repeated. In this case, the entire karaoke piece is scored according to a timing signal having a period longer (1 second) or shorter (0.1 second) than the basic period.
  (3) Overall evaluation / partial designation / evaluation level “sweet” or “spicy”
In cases other than the specific part, steps S4 → S5 → S12 → S7 → S8 → S9 are repeated, and this part is the same as (1). For the specific part, steps S4 → S5 → S12 → S13 → S8 → S9 are repeated, and scoring is performed according to a timing signal having a period longer or shorter than the basic period.
  (4) With partial evaluation / partial designation
Steps S4 → S14 → S9 are not repeated for the portions other than the specific portion, and scoring is not performed. For the specific portions, scoring is performed at any evaluation level set by repeating steps S4 → S14 → S13 → S8 → S9.
[0030]
  For example, if “Evaluation Type” is set to “Overall Evaluation”, “Evaluation Level” is set to “Hard”, and “Partial Designation” is set to “Rust” ((3)), For portions other than “rust”, steps S4 → S5 → S12 → S7 → S8 → S9 are repeated, and scoring is performed by the timing signal of the basic period. When the karaoke song progresses and becomes a “rust” portion which is a specific portion, steps S4 → S5 → S12 → S13 → S8 → S9 are repeated, and according to a timing signal having a cycle shorter than the basic cycle, it is “harder” than other portions. Scoring is done.
[0031]
  Further, for example, when “partial evaluation” is set in “evaluation type” and “singing” and “rust” are set in “partial designation”, as shown in FIG. ”And“ Rust ”are scored only, and the timing signal period for scoring of that portion is determined according to the setting of“ Evaluation Level ”“ Sweet ”,“ Normal ”,“ Spicy ”(a), As shown in (b) and (c), the length gradually changes.
[0032]
  As described above, in this embodiment, the karaoke device is provided with the scoring device 12, and the microcomputer 13 of the scoring device 12 has the karaoke song when the evaluation type is “overall evaluation” and no specific part is designated. A timing signal having a period corresponding to the evaluation level set by the operation button 14 is generated, and the sound signal is sampled in synchronization with the timing signal, and the pitch of the sound signal and the utterance timing shift with respect to the scoring reference signal The singer's singing was scored according to the magnitude of the deviation.
  Further, when the evaluation type is “overall evaluation” and a specific part is designated, the microcomputer 13 refers to the performance attribute signal of the given karaoke song and sets the specific part to the set evaluation level. A timing signal with a corresponding period is generated, and a timing signal with a basic period is generated for the other parts to perform scoring.
[0033]
  Therefore, for example, by setting the singing evaluation level to be “sweeter” or “spicy” than usual for the entire karaoke song or only a specific part such as designated “rust”, the singer can sing the karaoke song (especially It can be effectively used when aiming to improve the singing technique of a specific part that is not good at singing). In addition, it is possible to deal with the case where the singer wants to appeal to the listener the part that he is good at singing, or conversely when the part which is not good at singing is discounted and the scoring result is output.
[0034]
  Further, according to the present embodiment, when the evaluation type is “partial evaluation”, the microcomputer 13 generates a timing signal having a period corresponding to the set evaluation level only for the specified part of the karaoke song. So that the scoring is done. Therefore, it is more effective when the singer wants to improve the singing technique particularly for the specific part of the karaoke song by scoring only the specific part such as “rust” of the karaoke music.
  Furthermore, according to the present embodiment, the performance attribute signal data of the karaoke song is stored in the hard disk 3 separately from the musical sound data, and the performance attribute signal data is read out independently and output to the scoring device 12. The present invention can be carried out without changing the musical tone data of existing karaoke songs.
[0035]
  The present invention is not limited to the embodiments described above and illustrated in the drawings, and the following modifications or expansions are possible.
  In order to change the evaluation level, the sampling interval of the audio signal in the arithmetic processing unit 18 is changed by changing the cycle of the timing signal generated in the timing generation processing unit 17 of the microcomputer 13. Thus, the following method may be used.
  Step S7 in the flowchart shown in FIG. 5 is changed to step S7 ′ of “setting a normal evaluation criterion”, and step S13 is changed to step S13 ′ of “setting an evaluation criterion according to the evaluation level”. Here, the “evaluation standard” is an evaluation standard for calculating the pitch of the audio signal and the deviation of the utterance timing with respect to the scoring standard signal performed by the arithmetic processing unit 18. In the arithmetic processing in step S8, the sampling interval of the audio signal is always constant, and the arithmetic processing unit 18 performs arithmetic processing according to the evaluation criteria set in steps S7 'and S13', respectively.
[0036]
  For example, when the evaluation level is “normal”, the pitch is set at 25 cents and a deduction of 1 for the pitch, whereas when the evaluation level is “sweet”, the shift is 50 cents and the deduction is 1 In the case of “spicy”, the deviation is set to 10 cents and the deduction point is set to 1, and the calculation processing is performed using this evaluation criterion. Further, for example, in the case of “ordinary” with respect to a deviation of 10, 25, 50 cents, the deduction points 1, 2, and 3 are set respectively. If it is “spicy”, deduction points 1, 3, and 4 may be set.
[0037]
  Furthermore, as for the utterance timing, as in the case of the pitch, when the evaluation level is “normal”, the deviation is set to 1 point at 0.5 seconds, whereas the evaluation level is “sweet”. If the deviation is 0.8 second and the deduction point is 1 and “spicy”, the deviation is set to 0.3 second and the deduction point is set to 1, and the calculation process is performed using this evaluation criterion. Also, for example, when “ordinary” is set for a shift of 0.3, 0.5, and 0.8 seconds, deduction points 1, 2, and 3 are set for “ordinary”, and for “sweet”, deduction points are used 1, 1 and 2 may be set, and in the case of “spicy”, deduction points 1, 3 and 4 may be set, respectively.
  Further, by inserting steps S7 ′ and S13 ′ after steps S7 and S13, the above evaluation criteria may be changed simultaneously in addition to the change of the timing signal period.
[0038]
  When a plurality of specific parts are designated, different evaluation levels may be individually set for the specific parts, and the scoring evaluation level of each specific part may be changed.
  In addition to the normal overall evaluation in the case of (1), when only the one that changes the evaluation level for the entire karaoke song as in the case of (2) is executed, step S4 from the flowchart shown in FIG. S5, S12 and S14 may be deleted.
  In addition to the normal overall evaluation in the case of (1), when only a specific part of the karaoke song is to be scored at a predetermined evaluation level (“normal”) is shown in FIG. Steps S5, S6, S12 and S13 may be deleted from the flowchart, and if “YES” is determined in step S14, the process may proceed to step S7. Further, in the case where only a specific part of the karaoke song is to be scored at the set evaluation level as in the case of (4), steps S5, S6 and S12 may be deleted. In the above case, if the normal overall evaluation of (1) is unnecessary, step S4 may be further deleted, and if “YES” is determined in step S1, the process proceeds to step S14.
[0039]
  The performance attribute signal data may be stored in the hard disk 3 together with the musical sound data, and after the microcomputer 2 reads the integrated data, the performance attribute signal data and the musical sound data may be separated and output. .
  The function of the timing generation processing unit 17 in the scoring means may be configured by hardware such as a programmable counter.
  The data format of the performance attribute signal is not limited to that indicating the performance attribute according to the start time of the performance, but may be one indicating the performance attribute according to the count number of the musical sound (MIDI signal) data.
  When specifying a specific part, it may be specified by the karaoke song lyrics No. 1 and No. 2, etc., and more detailed designation such as “No. 2” “sing out” or “rust” may be given. Further, for example, a part that extends 4 beats or more in a certain pitch in a song may be specified.
  Instead of providing the indicator 20 on the scoring device 12, a display device is provided on the karaoke device side. When the scoring is completed, the microcomputer 13 of the scoring device 12 transmits the scoring result to the microcomputer 2 of the karaoke device, and the karaoke device side The scoring results may be displayed on the display. Moreover, you may display on CRT8 and 9 without providing the indicator for a scoring result display.
  The evaluation level is not limited to three levels of “sweet”, “normal”, and “spicy”, but may be set to four or more levels. Also, two stages of “sweet” and “normal” or “spicy” and “normal” may be used.
  The scoring device 12 may be configured separately from the karaoke device.
