The difficulty data 26a is included in each song of each karaoke song, and has a value corresponding to the difficulty of the karaoke song. As described above, the difficulty level data 26a is included in the karaoke song data 26 as the song data of the karaoke song.

In the difficulty data 26a, a value smaller than "100" is set as a reference value for a song considered to be difficult, with the value "100" being the center.
On the other hand, a value that is larger than “100” and smaller than “200” is set for a song that is considered to be simple. this"
When a value exceeding 200 ”is set, a full score is calculated as a final result even if a computable difference is obtained according to a calculation formula described later, so a value smaller than“ 200 ”is set. .

Therefore, when substituting into a calculation formula for scoring, which will be described later, the value set in the difficulty data affects the magnitude of the calculation result. That is, if the value is set to a value smaller than the reference value “100”, a high score is difficult to be output. Conversely, if a value larger than the reference value “100” is set, a high score is output. Easy to do.

The music performance data 26b further includes a vocal track 26b-1 and a back performance track 26b-
It is divided into two. And this vocal track 26
b-1 corresponds to the main melody data in the song data of the karaoke song.

Next, the operation of the karaoke apparatus 1 having the above configuration will be described with reference to the flowchart of FIG.

First, the CPU 14 in the karaoke apparatus 1
It is detected that the user inputs the number of the karaoke tune to sing through the push button 8 (S1). Note that CP
U14 keeps waiting for the input of the reservation number until there is an input from the user.

When the user inputs a reservation number, the CPU 14 in the karaoke apparatus 1 searches the HDD 15 for karaoke music data 26 of the corresponding music (S2), and transfers the karaoke music data 26 to the I / O circuit 24. , RS terminal 2
The data is transmitted to the scoring device 99 via the third and the third 95 (S3).

In this case, of the karaoke music data 26 stored in the HDD 15, the difficulty data 26a
Alternatively, only the music performance data 26b may be transmitted to the scoring device 99.

Next, the CPU 14 in the karaoke apparatus 1
The start of the performance of the karaoke song data read from the DD 15 is notified to the scoring device 99 via the I / O circuit 24 and the RS terminals 23 and 95 (S4). This can be notified to the scoring device 99 by transmitting a flag or the like indicating the start of the performance.

Next, the CPU 14 in the karaoke apparatus 1
The music performance data 26b in the karaoke music data 26 read and received from the DD 15 is sent to the music performance circuit 17, and the speaker 4 is output via the music output terminal 11 and the amplifier 2.
Output the karaoke performance from the karaoke music data 26 (S5).
6 and display the lyrics on the CRT display device 3 via the video output terminal 10 (S6). And this S5
And the operations of S6 are repeated until the performance of one karaoke tune is completed.

When the performance is completed (S7 • Ye
s), the end of the performance is notified to the I / O circuit 24, the RS terminal 23, and the scoring device 99 (S8), and the process returns to the music selection waiting (S1).

Next, the operation of the scoring device 99 will be described with reference to the flowchart of FIG. First, the scoring device 99
The CPU 94 is in a data waiting state until the music data 26 is transmitted from the karaoke apparatus 1. Then, karaoke song data 26 is transmitted from the RS terminal 23 of the karaoke apparatus 1 and received (S1), and the karaoke song data is temporarily stored in the RAM 92 (S2). Then, it waits until the start of the performance is notified from the karaoke apparatus 1 (S
3).

As described above, when the flag indicating the start of the performance is received, the CPU 94 obtains the voice singing by the user from the microphone 5 through the voice input terminal 97, and transmits the pitch to the voice pitch obtaining circuit 92. The data is compared with the vocal track data 26b-1 as the main melody data in the music data 26 on the RAM 93 corresponding to the data, and the absolute value of the difference is sequentially added (S5). Then, the operations up to S4 and S5 described above are repeated until the performance of the karaoke song ends.

When the CPU 94 is notified of the end of the performance via the RS terminal 23 of the karaoke apparatus 1 (S6: Yes), the vocal track data and the audio data are obtained by repeating the operations of S4 and S5. The sum of the deviation obtained by adding the random number α generated by a known method to a value obtained by adding the deviation in the pitch or the pitch to the above is calculated by the following formula. That is, scoring result = sum of pitch or pitch difference + α
(Random number). Note that, in this sense, the CPU 94
It corresponds to a scoring unit and a random number adding unit in the present invention.

Then, the scoring result and the value in the difficulty data 26a in the music data 26 on the RAM 92 are substituted into a calculation formula expressed by, for example, final result = (500-scoring result) + difficulty data × 5. Then, the final scoring result is calculated by a numerical value (S7). Note that, in this sense, the CPU 94 corresponds to the difficulty data acquisition unit and the reflection unit in the present invention.

Thereafter, the CPU 94 outputs the final result for 7 seconds.
It is displayed on the segment LED 98 (S8).

In the above equation, the CPU 94
The voice singing by the user input from the microphone 5 is obtained through the voice input terminal 97, and the pitch is converted into data by the voice pitch obtaining circuit 92 (S4). In comparison with the vocal track data 26b-1 as the main melody data, when adding the absolute values of the differences sequentially, it is premised that some errors will occur from the viewpoint of accuracy. That is, a voice singing by the user input from the microphone 5 is obtained through the voice input terminal 97, and the pitch is converted into data by the voice pitch obtaining circuit 92 (S4), and the music data 26 on the RAM 93 corresponding to the data is obtained. The accuracy of the difference value in comparison with the vocal track data 26b-1 as the main melody data in the above will depend largely on the functionality of the CPU 94 for calculating and the voice pitch obtaining circuit 92 for obtaining the voice pitch. . Therefore, a random number α is added to the scoring result by those so as not to be affected by the dependency.

Then, as it is, the result of adding the random number α may cause the same result to be obtained for any karaoke music score. You may have doubts.

Therefore, by assigning difficulty data corresponding to the song data to the karaoke song data itself, the difficulty data value is reflected in the scoring result calculated by the above-described device, thereby making it possible to create a difficult karaoke song. For karaoke songs, it is easy to produce a difficult final result.

Thus, for example, as shown in FIG. 6A, the value of the difficulty data 26a in the karaoke music data 26 corresponding to the karaoke music A is the reference value of 10
If 0 is set, the karaoke song is requested and the singing is scored. If the singing is scored out of 100, the vocal data as the main melody data and the microphone 5 are input. If the sum of the differences from the audio data is less than 900,
It will be a perfect score. Note that the cumulative difference is less than 900,
Even if the calculation result is a value exceeding 100 points, all 100
A perfect score.

On the other hand, as shown in FIG. 6B, when the value of the difficulty data 26a in the karaoke song data 26 corresponding to the karaoke song B is set to, for example, 50, according to the above formula, If the sum of the differences between the vocal data as the main melody data and the voice data input from the microphone 5 does not take a value of 650 or less, a full score will not be obtained.

Therefore, the karaoke song B has a difference of about 250 as difference data as compared with the karaoke song data 26 corresponding to the karaoke song A in which the difficulty level 100 is set. That is, the final result of the karaoke song data 26 corresponding to the karaoke song B is lower by that value,
The score is more difficult to obtain than the karaoke song data 26 corresponding to the karaoke song A.

Then, the karaoke song A as the user's consciousness
If the karaoke song B is harder to sing than the karaoke song B, by giving such a final result, it is possible to prevent the user from asking questions about the scoring.

Further, as shown in FIG.
When singing a karaoke song C in which 80 is set, a full score can be obtained even if the total difference between the vocal data as the main melody data and the audio data input from the microphone 5 is 1300.

If the karaoke song C is a song that can be easily sung by anyone, it can be satisfied with the final result according to the above formula.

Then, the CPU 94 displays the final result on the 7-segment LED 98 for a certain period of time,
Then, the music data 26 on the third karaoke device 3 is deleted (S9), and the process returns to waiting for karaoke music data from the karaoke device 1 (S1).

As is clear from the above description, in the scoring device 99 as the karaoke scoring device of the present invention, the voice pitch obtaining circuit 91 as the voice data obtaining means uses the voice singing voice of the user along with the karaoke tune. The data is acquired via the microphone 5, and the CPU 94 as a scoring unit performs the music performance data 26b in the karaoke music data 26 as the main melody data in the audio data acquired by the audio pitch acquisition circuit 91 and the main melody data in the music data of the karaoke music. The singing ability of the user is scored based on the difference from the pitch or pitch with the middle vocal track data 26b-1.

Then, C as the difficulty data acquisition means
PU94 generates the difficulty data 26 corresponding to the karaoke song.
a, and the CPU 94 as reflection means
The difficulty level data 26a also obtained by the CPU 94 is calculated based on the scoring result obtained by the CPU 94 based on a predetermined calculation formula, and the difficulty level of the karaoke song is reflected.

Accordingly, the karaoke song data 26 has the difficulty data 26a of the song, and the scoring result value including the random number element and the difficulty value read from the difficulty data are calculated based on a predetermined formula. The score of a song that seems to be difficult is low and the score of a song that seems easy is high because a predetermined sum or product is calculated, so the final result by the scoring device 99 is given to the singer who is the user. Can reduce the likelihood of the truthfulness of the

The karaoke scoring apparatus of the present invention is not limited to the above-described embodiment, but can be applied to various applications without departing from the gist of the present invention.

For example, in this embodiment, the reference value of the difficulty data 26a in the karaoke music data 26 is set to 10
Although set to 0, the reference value may be variously changed according to the method of calculating the score.

Further, in this embodiment, the configuration in which the difficulty data 26a is incorporated in the karaoke music data 26 has been described. However, it is not always necessary to incorporate the difficulty data into the karaoke music data. In a separate storage medium, for example, multiple levels of difficulty data are stored, and identification information is attached to the data, and the karaoke song data side simply stores the identification information attached to the aforementioned difficulty data. Based on this, only search data for reading the difficulty data may be added.

[0070]

As is apparent from the above description,
According to the karaoke scoring device of the first aspect, the reflecting means reflects the difficulty data acquired by the difficulty data acquiring means on the scoring result by the scoring means. Scoring strictly according to
Conversely, for easy songs, a sweet score can be given accordingly, and the reliability of the score result can be enhanced for karaoke users.

According to the karaoke scoring device according to the second aspect, random numbers are added to the scoring result by the karaoke scoring device by the random number adding means. Also, since the reflecting means reflects the difficulty data on the scoring result of the scoring means, it is possible to obtain a scoring result that is plausible for the user even if the karaoke scoring device is used.

Further, according to the karaoke scoring device according to the third aspect, the difficulty data obtaining means can obtain the difficulty data from the music data read out from the storage means in the karaoke performance operation. By reading out only the data, scoring by the scoring means becomes possible, and the configuration of the apparatus becomes simpler.

According to the karaoke scoring device of the fourth aspect, scoring is performed by the scoring means based on the difference in pitch or pitch between the voice data sung by the user and the main melody data of the karaoke song. The reflecting means reflects the difficulty data on the scoring result by the scoring means, so for the user, the severe scoring result for the so-called difficult karaoke song that is difficult to match the singing voice to the main melody, on the contrary, the singing voice For a karaoke song with a low difficulty, which is easy to match with the main melody, a sweet scoring result can be recognized. Therefore, it is possible to reduce the possibility that the user is doubted about the truth of the scoring result.
