The audio mixer 6 outputs the audio signal
Mixing (mixing) the tone signal of the karaoke tune reproduced in the DI sound source 4 based on the set volume balance
Then, the signal is output to the speaker 7.

The audio signal from the microphone 11 is passed through the audio mixer 6 to a scoring device (karaoke scoring device) 12.
Of the scoring device 1
The input / output terminal 2 is connected to the input / output port of the microcomputer 2. The scoring device 12 compares and calculates a scoring reference signal such as a pitch or timing related to a melody sung as a karaoke tune provided from the microcomputer 2 and an A / D-converted audio data input from the microphone 11,
The singer's singing is scored. The above constitutes the karaoke apparatus.

FIG. 1 shows a detailed configuration of the scoring device 12 by functional blocks. In FIG. 1, the scoring device 12 is mainly configured by a microcomputer 13.
As for the inside of the microcomputer 13, functions realized mainly by software are represented by blocks.

The operation buttons (evaluation level setting means, scoring part designating means, change part designating means) 14 are operated by the user to designate a specific part for designating the grading of the karaoke tune, and to make the grading of the karaoke song sweet or difficult. Is provided so that you can set the evaluation level for
The operation signal is provided to the input processing unit 15 of the microcomputer 13. The input processing unit 15 writes the operation signal given by the operation button 14 into the operation information storage unit 16a of the memory 16 composed of a RAM or the like,
Information on the settings is stored.

The timing generation processing section (scoring means) 17 of the microcomputer 13 is provided with the above-mentioned performance attribute signal. The timing generation processing unit 17 outputs a timing signal of an appropriate cycle 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 period and output time of the timing signal are determined by reading the setting information stored in the operation information storage unit 16a,
It is determined by referring to the performance attribute signal.

The arithmetic processing section (scoring means) 18 is supplied with a voice signal and a scoring reference signal, and the arithmetic processing section 18 synchronizes with the timing signal supplied from the timing generation processing section 17. The voice signal is sampled, the pitch of the voice signal and / or the utterance timing is shifted with respect to the scoring reference signal, and the singer's singing is scored according to the magnitude of the shift.

More specifically, the arithmetic processing unit 18 determines how many cents of the pitch of the sampled audio signal deviates from the pitch or utterance timing determined in the scoring reference signal, or the time of the utterance timing. Scoring is performed by subtracting points from a predetermined origin (for example, 100 points) according to the deviation. The arithmetic processing unit 18 stores the information on the scoring performed for each input of the timing signal in the memory 16.
Are sequentially stored in the scoring information storage unit 16b.

The performance attribute signal is also given to the display processing unit 19, and when the performance attribute signal indicates "end of performance", the display processing unit 19 stores the performance attribute signal in the scoring information storage unit 16b. The scoring information is written into the scoring result storage unit 16c as the scoring result, and the scoring result is displayed on the display 20 composed of, for example, 7-segment LEDs. The above constitutes the karaoke scoring device 12.

Next, the operation of the present embodiment will be described with reference to FIGS. The user of the karaoke apparatus performs necessary settings by operating the operation buttons 14 of the scoring apparatus 12. In this case, as shown in FIG. 4, there are three setting items of “evaluation type”, “evaluation level”, and “partial designation”.

There are two types of "evaluation types", "whole evaluation" and "partial evaluation". The former is selected when the singer performs the entire singing of a karaoke song, and the latter is selected. This is selected when only a specific part of the singing is evaluated.

The "evaluation level" is the strictness of the singing score. For example, there are three types of "sweet", "normal", and "spicy" which are expressed in easy-to-understand words. The default rating level is set to "Normal", but select "Sweet" if you want to score with a more gradual rating level, or select "Spicy" if you want to score with a stricter rating level. I do.

"Part designation" designates a specific part of the singing. For example, "singing out", "rust",
There are three types of "singing end". If "Evaluation Type" is set to "Overall Evaluation" and "Evaluation Level" is set to "Sweet" or "Spicy", and if any of the above three types is specified, the specified specification The part is scored at the evaluation level set in the “evaluation level”, and the other parts are scored at the default evaluation level (normal).

When "partial evaluation" is set in the "evaluation type", only the designated specific part is scored at the evaluation level set in the "evaluation level", and the other parts are scored. No scoring is done. In “partial designation”, two of the above three types are used.
It is also possible to specify a combination of the two.

Next, the user operates the various keys on the operation panel 1 or the remote controller 1a to input the number (song number) assigned to the karaoke song selected by the singer. When the music number is input, the microcomputer 2 as the performance attribute signal output means reads out the musical sound and lyrics data and the performance attribute signal data corresponding to the music number from the hard disk 3 and outputs the musical sound data to the MIDI tone generator 4. The performance attribute signal is output to the scoring device 12 in synchronization with the musical sound data, and the lyrics data is output to the video mixer 5. M
The IDI sound source 4 outputs musical tones corresponding to the timbres of various musical instruments in accordance with the given MIDI signals, and supplies the audio mixer 6 with the musical sound signals of the karaoke music.

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 the video data into an NTSC signal, and
Output to The video mixer 5 combines the lyric data provided by the microcomputer 2 with the video signal output by the disc player 10 and outputs them to the CRTs 8 and 9 respectively. The CRTs 8 and 9 display the given video data on the screen.

On the other hand, the music signal of the karaoke tune supplied to the audio mixer 6 is amplified according to the set volume level and supplied to the speaker 7, thereby being reproduced as a karaoke tune. The singer listens to the karaoke song and sings a song so as to input a voice to the microphone 11 while looking at the lyrics displayed on 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 music.

FIG. 5 is a flowchart showing the control contents of the microcomputer 13 of the scoring device 12. The input processing unit 15 of the microcomputer 13 firstly asks "Do you want to start playing?"
And determination steps S1 and S2 of "button operation?"
In this state, it is determined whether or not a code indicating "start of performance" has been output as a performance attribute signal and whether or not the operation button 14 has been operated.

If the operation button 14 is operated to set the karaoke scoring device 12 before the performance of the karaoke song as described above, the input processing unit 15 determines "YES" in step S2, and The processing moves to the processing step S3 of “Storing operation information”. 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 the operation information as the operation information storage unit 1 of the memory 16.
6a to be stored. Then, control goes to a step S1.

When the performance of the karaoke music is started and the code indicating "start of performance" is output from the microcomputer 2 as a performance attribute signal as described above, the input processing unit 15 determines "YES" in step S1. Judge
The process proceeds to the determination step S4 of “whole evaluation?”.

In the determination step S4, the timing generation processing section 17 refers to the operation information storage section 16a to determine whether the selected evaluation type is "whole evaluation". If “overall evaluation” is selected and the timing generation processing unit 17 determines “YES”, “partly specified?”
When "partial evaluation" is selected and "NO" is determined, the process proceeds to "determination part?" Determination step S14.

In the determination step S5, the timing generation processing section 17 similarly determines whether or not a partial designation has been made by referring to the operation information storage section 16a. The process proceeds to the determination step S12 of “specific part?”, And if the determination is “NO” because no part is specified, the process proceeds to the determination step S6 of “evaluation level“ normal ”?”.

In the determination step S12, the timing generation processing section 17 refers to the performance attribute signal of the karaoke tune to determine whether or not the current progress state of the karaoke tune is in the portion designated as the specific portion. There is no "N
If "O" is determined, the process proceeds to a "basic timing generation" processing step S7. If the determination is "YES" in the specific portion, the process proceeds to a "timing generation according to evaluation level" processing step S13.

Further, in the judgment step S14, the timing generation processing unit 17 makes the same judgment as in step S12. However, when the judgment is "YES", the processing shifts to step S13, and when the judgment is "NO", the processing shifts to judgment step S9. .

In determination step S6, the timing generation processing section 17 determines whether or not the evaluation level set by referring to the operation information storage section 16a is "normal", and determines whether the set evaluation level is "normal". If the determination is "YES", the flow proceeds to step S7. If the evaluation level is "sweet" or "spicy" and the determination is "NO", the flow proceeds to processing step S13.

In the processing step S7, the timing generation processing section 17 generates a timing signal of a basic cycle corresponding to the evaluation level “normal” and outputs it to the arithmetic processing section 18. In the processing step S13, the timing generation processing section 17 determines that the evaluation level is “sweet” or “spicy”.
Alternatively, a timing signal having a cycle corresponding to “normal” is generated and output 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". Is 0.5 seconds, the period of the timing signal corresponding to “sweet” is 1 second,
The cycle of the timing signal corresponding to "spicy" is set to a time such as 0.1 second. Then, steps S7 and S13
Is completed, the processing shifts to the processing step S8 of the “calculation processing”.

In processing step S8, the arithmetic processing unit 1
8 samples the audio signal in synchronization with the timing signal supplied from the timing generation processing unit 17 and determines how many cents the pitch of the audio signal deviates from the pitch or utterance timing specified in the scoring reference signal. The scoring is performed by subtracting points from a predetermined origin (for example, 100 points) according to 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 16b of the memory 16. Next, the process proceeds to a judgment step S9 of "end of performance?"

In the judgment step S9, the arithmetic processing unit 1
Reference numeral 8 refers to the performance attribute signal to determine whether or not the performance of the karaoke tune has ended. If a signal indicating "end of performance" has not been output and the determination is "NO", the process shifts to step S4, and the above procedure is repeated to continue scoring. Also,
If a signal indicating "end of performance" has been output and it is determined "YES", processing step "Summation of scoring information" S10
Move to

In the processing step S10, the display processing unit 19 writes the scoring result obtained by summing the scoring information written in the scoring information storage unit 16b into the scoring result storage unit 16c. Then, the processing step S11 of “display of the scoring result”
Then, the display processing unit 19 sets the scoring result storage unit 16c
When the scoring result written in is output to the display device 20 and displayed, the process ends.

There are various scoring modes for the above processing depending on the selection by the operation button 14. For each mode, the flow of processing from the performance start to the performance end is as follows.

In the case of 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 the conventional karaoke grading apparatus, and the entire karaoke music is scored according to the timing signal of the basic period (for example, 0.5 seconds).

In the case of 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 song is scored in accordance with a timing signal having a period longer (1 second) or shorter (0.1 second) than the basic period.

In the case of overall evaluation / part designation / evaluation level “sweet” or “spicy” In cases other than the specific part, steps S4 → S5 → S12 →
S7 → S8 → S9 are repeated, and the same processing is performed for this part. For the specific part, step 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.

In the case of partial evaluation / partial designation Steps S4 → S14 → S9 are not repeated for other than the specific part, and no scoring is performed. Only the specific part is set by repeating steps S4 → S14 → S13 → S8 → S9. Scoring is performed at any of the evaluation levels.

For example, when “overall evaluation” is set in “evaluation type”, “spicy” is set in “evaluation level”, and “rust” is set in “partial designation”, Steps S4 → S5 → S12 → S7 → S8 → S9 are repeated for parts other than “rust”, and scoring is performed using the basic cycle timing signal. When the karaoke song progresses and reaches the part of the "rust" which is a specific part, steps S4 → S5 → S12 → S13 → S8 →
S9 is repeated, and "sharper" scoring is performed according to the timing signal having a cycle shorter than the basic cycle.

For example, when "partial evaluation" is set in "evaluation type" and "singing out" and "chorus" are set in "partial designation", as shown in FIG. The scoring is performed only for the “singing out” and “rust” parts, and the cycle of the timing signal for the scoring of that part is determined according to the setting of “evaluation level” of “sweet”, “normal”, and “spicy” ( a), (b), (c)
As shown in FIG.

As described above, in the present embodiment, the karaoke apparatus is provided with the scoring device 12, and the microcomputer 13 of the scoring device 12 is provided when the evaluation type is "overall evaluation" and no specific part is designated. For the entire karaoke song, a timing signal having a cycle corresponding to the evaluation level set by the operation button 14 is generated, and the audio signal is sampled in synchronization with the timing signal, and the pitch and utterance of the audio signal with respect to the scoring reference signal are generated. Calculate the timing deviation,
The singer's singing is scored according to the size of the deviation.

When the evaluation type is "whole evaluation" and a specific portion is designated, the microcomputer 13 refers to the performance attribute signal of the given karaoke tune and sets the specific portion. A timing signal having a cycle corresponding to the evaluation level is generated, and a timing signal having a basic cycle is generated for the other portions to perform scoring.

Therefore, for example, by setting the singing evaluation level to “sweet” or “spicy” as compared to the normal singing for only the entire karaoke song or a specific portion such as a designated “rust”, the singer can perform the karaoke. The present invention can be effectively used when aiming at improving the singing technique of a song (particularly, a specific portion where the singing is not good). Further, it is possible to cope with a case where a singer wants to appeal to a listener for a part that is good at singing, or conversely, a case where he wants to output a scoring result by discounting a part that is not good at singing.

Further, according to the present embodiment, the microcomputer 13
In the case where the evaluation type is "partial evaluation", a scoring is performed by generating a timing signal having a cycle corresponding to the set evaluation level only for a specified specific portion of the karaoke song. Therefore, by scoring only a specific portion of the karaoke song, such as “rust”, it is more effective for the singer to improve the singing technique especially for the specific portion of the karaoke song.

Furthermore, according to the present embodiment, the performance attribute signal data of the karaoke tune is stored in the hard disk 3 separately from the tone data, and the performance attribute signal data is read out independently and output to the scoring device 12. As a result, the present invention can be implemented without making any changes to the tone data of existing karaoke songs.

The present invention is not limited to the embodiment described above and shown in the drawings, and the following modifications or extensions are possible. 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. Then, the following method may be adopted.

Step S7 of the flowchart shown in FIG.
Is changed to step S7 'of "set a normal evaluation criterion", and step S13 is changed to step S13' of "set an evaluation criterion according to an evaluation level". Here, the “evaluation criterion” is an evaluation criterion for calculating a shift between the pitch and the utterance timing of the audio signal with respect to the scoring reference signal performed by the arithmetic processing unit 18. Then, in the arithmetic processing in step S8, the sampling interval of the audio signal is always fixed, and the arithmetic processing unit 18 determines in steps S7 'and S7.
At 13 ', arithmetic processing is performed according to the evaluation criteria set respectively.

For example, as for the pitch, when the evaluation level is “normal”, the deviation is set to 25 cents and the deduction point is 1, whereas when the evaluation level is “sweet”,
If the gap is 50 cents and the penalty is 1, the score is 1
A deduction of 1 is set at 0 cents, and arithmetic processing is performed based on this evaluation criterion. Further, for example, when the difference is 10, 25, and 50 cents, the deduction points 1, 2, and 3 are set in the case of "normal", and the deduction points 1, 1, and 3 are set in the case of "sweet".
2 may be set, and in the case of “spicy”, deduction points 1, 3, and 4 may be set, respectively.

Further, as for the utterance timing, similarly to the pitch, when the evaluation level is “normal”, the deviation is set to 0.5 seconds and the deduction point is 1, whereas the evaluation level is “sweet”. In the case of "", the deviation is 0.8 seconds and the deduction 1,
In the case of "Spicy", the gap is 0.3 seconds and the penalty is set to 1,
The arithmetic processing is performed based on the evaluation criteria. Also, for example,
In the case of “normal”, deductions 1, 2, and 3 were set for the shifts of 0.3, 0.5, and 0.8 seconds, respectively. 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-mentioned change of the evaluation criterion may be simultaneously performed in addition to the change of the cycle of the timing signal.

When a plurality of specific parts are designated, different evaluation levels may be individually set for each of the specific parts, and the evaluation level of the scoring of each specific part may be changed. In addition to the normal overall evaluation in the case of (1), in the case of executing only the one that changes the evaluation level for the entire karaoke song as in the case of (2), steps S4, S5, S12 and S1 from the flowchart shown in FIG.
4 may be deleted.

FIG. 5 shows a case where, in addition to the normal overall evaluation in the above case, only a specific part of the karaoke tune is scored at a predetermined evaluation level ("normal"). Step S from flowchart
5, S6, S12 and S13 are deleted, and step S1
If it is determined “YES” in step 4, the process may proceed to step S7. In the case where only a specific portion of the karaoke song is scored at the set evaluation level as in the case of step S5, steps S5, S6, and S12 may be deleted. In the above case, if the normal overall evaluation is unnecessary, step S4 may be further deleted, and if "YES" is determined in step S1, the process may proceed to step S14.

The performance attribute signal data is integrated with the musical tone data and stored in the hard disk 3. After the microcomputer 2 reads out the integrated data, the microcomputer 2 separates the performance attribute signal data and the musical tone data and outputs them. May be.
The function of the timing generation processing unit 17 in the scoring unit is
You may comprise with hardware, such as a programmable counter. The data format of the performance attribute signal is not limited to the format indicating the performance attribute according to the start time of the performance, but may be the format indicating the performance attribute according to the count number of the musical tone (MIDI signal) data. In specifying the specific portion, the first or second lyrics of the karaoke song may be specified, and more detailed specification such as "singing out" or "chorus" of the second song may be performed. In addition, for example, a portion of the song that extends four or more beats at a fixed pitch may be designated.

Instead of providing the display 20 on the scoring device 12, a display is provided on the karaoke device side, and the microcomputer 13 of the scoring device 12 transmits the scoring result to the microcomputer 2 of the karaoke device when the scoring is completed. The scoring result may be displayed on the display of the karaoke apparatus. Further, the display may be displayed on the CRTs 8 and 9 without providing a display for displaying the scoring result. The evaluation level is not limited to three levels of “sweet”, “normal”, and “spicy”, and may be set to four or more levels. Further, 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.

[0071]

Since the present invention is as described above,
The following effects are obtained. According to the karaoke scoring device according to claim 1 or 2, the scoring means performs scoring according to the evaluation level set by the evaluation level setting means (Claim 1). Specifically, the singer responds to the scoring reference signal. Scoring is performed by sequentially calculating the deviation of the voice signal of the singing according to the input of the timing signal, and the period of the timing signal is changed according to the evaluation level set by the evaluation level setting means (claim 2). The score of the singer's singing can be made sweeter or harder than usual.

According to the karaoke scoring device of the third aspect, the scoring means specifies the karaoke tune designated by the scoring part designation means by referring to the performance attribute signal of the karaoke tune inputted from the outside. Since only the portion is scored, only the specific portion of the karaoke song that the singer wants to score can be selectively scored.

According to the karaoke scoring device of the fourth aspect, the scoring means refers to the performance attribute signal of the karaoke tune inputted from the outside, thereby specifying the specific portion of the karaoke tune designated by the change portion designation means. Since the evaluation level is changed only for, the evaluation level can be changed for a specific portion of the karaoke song sung by the singer.

According to the karaoke scoring device of the fifth aspect, the scoring means specifies the karaoke tune designated by the scoring part designation means by referring to the performance attribute signal of the karaoke tune inputted from the outside. Since only the portion is scored, only the specific portion of the karaoke song sung by the singer can be scored at the set evaluation level.

According to the karaoke scoring device of the sixth aspect, the evaluation level setting means can set the evaluation level individually for a specific portion of the karaoke song specified by the scoring portion specifying means. Therefore, it is possible to score each specific portion of the karaoke song at a different evaluation level.

According to the karaoke apparatus according to the seventh or eighth aspect, since the karaoke scoring apparatus according to any one of the first to sixth aspects is provided, it is possible to change the evaluation level of the singing score or change the designated karaoke song. For example, it is possible to score only a specific part of.

According to the karaoke apparatus of the ninth aspect, the performance attribute signal output means reads out the data of the performance attribute signal stored separately from the music data of the karaoke tune into the storage means, and outputs the performance attribute signal. Since the output is performed, the performance attribute signal can be output without changing the performance data of the karaoke song.
