Description

Karaoke host device and program {KARAOKE HOST DEVICE AND PROGRAM}

The present invention relates to a karaoke host apparatus and program that indicates whether or not a karaoke piece of music that has not been sung is available to the user on the basis of music data of the karaoke piece of music and a song history of the karaoke user.

Many new songs are released and these songs are gradually called karaoke. However, even if new songs are released, whether or not these songs are vocal to a karaoke user is a problem that cannot be known unless the actual song is tried.

The karaoke terminal is provided with a key changing function for shifting the pitch of the karaoke music to a range that can be uttered by the singer. However, this key change function is also difficult to set up if the singer himself does not have enough knowledge of his or her voiceable area. For this reason, I usually try to set the key change several times and find the key setting that suits me. Therefore, even if it is thought that changing the key is possible, there is a problem in which it is impossible to know in detail how much the key should be changed.

Thus, a method of analyzing whether or not the user can sing a karaoke piece is provided.

For example, a method of analyzing the vocal range of karaoke software, which has been assigned a data representation in the form of an electronic score, for the purpose of providing a method for analyzing the vocal range of the karaoke software in advance, the electronic music of the karaoke software to be analyzed. There is provided a singing range analysis method that extracts the main pitch from the data and collects the pitch information and the length information of the whole parts constituting the main pitch and creates the song range data (see Patent Document 1).

Patent Document 1: Japanese Patent Application Laid-Open No. 2002-108373

However, even if the song range data is written, it is not indexed to what extent each user can actually sing, so the problem is that it is not clear whether the user can sing a song that is not yet sung, such as a new song. have.

However, the range of each user is hardly changed unless there is a change due to aging or growth. However, it is difficult for an average karaoke user to know exactly what the range of his or her own is, unless he or she has previously investigated the information of the range or has an absolute pitch.

In addition, it is difficult to determine in advance whether the target music can be singed by changing the key. In other words, there is no means to increase one's repertoire by knowing what other songs are vocal at their own singing level.

Accordingly, an object of the present invention is to provide a karaoke host device and a program that can indicate an index of how much karaoke users can sing about a target piece of music that has not been sung yet.

Example 1

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 is an explanatory diagram showing the overall system configuration of the present application, wherein a karaoke terminal 3 installed on a karaoke shop side and a user terminal 4 installed on a karaoke user side are installed on a karaoke operator side through a communication line 2. It is connected with the apparatus 1.

In addition, in the system configuration shown in FIG. 1, only one karaoke host device 1, karaoke terminal 3, and user terminal 4 are shown, respectively. In addition, the communication line 2 can use various lines, such as the Internet and a public telephone line.

Although not shown, the karaoke host apparatus 1 stores karaoke data including a central processing unit including a CPU, a ROM, and a RAM, accompaniment music data of karaoke music, and a sum total length of pitches of each of the pitches of the lyrics and the main tune music data. A computer operated by a karaoke operator equipped with a karaoke database, a user database storing data such as identification information and vocal history information of a karaoke user, a communication control unit for controlling communication with the communication line 2, and the like.

When the user requests delivery of karaoke data from the karaoke terminal 3 to the karaoke host device 1, the central processing unit extracts the requested karaoke data from the karaoke database and sends it to the communication line 2 through the communication control unit. Then, the karaoke data is delivered from the karaoke host device 1 to the karaoke terminal 3. In addition, the central processing unit of the karaoke host device 1 performs various information processing such as an operation log uploaded from the karaoke terminal 3. Furthermore, the karaoke terminal 3 collects singing history information for each user at an opportunistic opportunity and stores it as a user database.

2 is an explanatory diagram of a hardware configuration of the karaoke terminal 3. The karaoke terminal 3 includes a central processing unit 11 including a CPU, a ROM, and a RAM, an external storage unit 12 such as a hard disk or an optical disk, and a user interface unit 13 for performing input from and response to a user. ), A communication control unit 15 communicating with the karaoke host device 1 through a communication line 2, an image display unit 16 using a CRT, a liquid crystal screen, or the like, and image data to be displayed on the image display unit 16. The image processing unit 17, an audio generation unit 18 for generating a karaoke audio signal based on music data such as a MIDI format, amplifying the audio signal from the accompaniment music data or the microphone 20, And an audio processor 19 for outputting.

In addition, the user interface unit 13 includes a main body operation panel of the karaoke terminal 3, and at the same time, a remote control terminal 14 having infrared communication means for performing instructions for searching, selecting and playing karaoke music, It is attached.

Although not illustrated, the user terminal 4 may include a central processing unit including a CPU, a ROM, and a RAM, a display unit using a CRT, a liquid crystal display, an input unit such as a keyboard, a mouse, a microphone, an output unit such as a speaker, a headphone, a communication line ( 2) An information processing device having a communication control unit for controlling communication with 2), which includes a personal computer, a mobile phone, a PHS, a PDA, and the like.

First, the principal rate database unit of a music unit is demonstrated.

This extracts the main tune data from the music data of the karaoke piece, and calculates the sum of the note lengths for each pitch of the main tune data in the unit of music, thereby dataizing.

Specifically, in the case of MIDI, the main tune data is extracted from the MIDI file, the sum of the note lengths is calculated for each pitch of the main tune data, and the database is composed of music units. As a result, it is possible to know how long each pitch included in the main tune data is output.

For note lengths, note length data in 1/1000 second is used for MIDI. Otherwise, note length is calculated based on the number of beats and tempo.

Next, a description will be given of means for dividing all the sound ranges used in the karaoke into a plurality of stages based on information on the user's singing level.

Information about the song level of the user in this embodiment is obtained from the song history of the karaoke music of the user. Specifically, first, song history data for each user, that is, collected by each karaoke terminal 3 and stored in the user database of the karaoke host device 1 together with identification information such as a user's unique member number, that is, Obtains data about historical karaoke music.

The vocal manpower data is not only the case where the karaoke host apparatus 1 automatically collects and stores the music data sung by the user from each karaoke terminal 3, and stores the data in the user database, as well as the remote control terminal 14 or the user terminal 4. The user may directly input identification information of a song having a good track record by the user, and transmit the information to the karaoke host device 1 via the communication line 2 and store it in the user database. In the case where the karaoke piece of music is sung by changing the key, information on the key change, for example, information on the key change, for example, a key being raised, is stored in the user database.

Furthermore, the information about the song level of the user in the present embodiment is not limited to the case of cooking for all the karaoke pieces of music having the user's singing history, and is acquired for some karaoke pieces with the song history. You may.

Specifically, the user inputs the identification information of the piece of music that the user wants to be excluded when determining the stage among the songs having a history which the user sings by the input unit of the remote control terminal 14 or the user terminal 4 and communicates the information. It transmits to the karaoke host apparatus 1 via the line 2, and stores it as a target object out-of-date music in a user database. And when acquiring the data about the karaoke music with a vocal history in order to determine a user's stage from a user database, it acquires except the target object desired music data. In this way, the user can deal with such cases as "I want to exclude this music from the target music when deciding my stage because it was called from the beginning to the end", and it is possible for the user to determine the appropriate stage.

Next, the vocal music data is extracted from the music data such as MIDI stored in the karaoke database for the karaoke music having the song history of the corresponding user when determining the user's stage. The total value of the note lengths for each pitch is calculated based on the main tune data of all the extracted pieces. Also, in the case of a piece of music in which the user has changed the key and sang in the user database, the pitch data after the key change is used.

Then, based on the information on the song level of the user, the sum of the lengths of each pitch is divided into a plurality of stages based on the information.

3 is an explanatory diagram of an example of a sound range divided into a plurality of steps in a user personal unit. The lines of the music A, the music B, the music C, and the music D represent the range of each music. In the case of this user, there is a history of four pieces of music A, music B, music C, and music D, and the high range of the song level is set as stage A based on the information about the song level, and from there, the high-pitched sound or the bass sound. As it moves away from the direction, it is divided into seven stages: step B treble, step C treble, step D treble in the high pitch direction, step B bass, step C bass, and step D bass in the low pitch. However, the steps are not limited to these seven steps, and may be any number if it is divided into a plurality of steps.

4 is a specific example of population information in the case of determining a user's stage based on the average pitch and the standard deviation. In this case, it is assumed that the cumulative data of the MIDI main tune data of the whole musical piece having the song history is assumed, and the distribution of the pitch is normal distribution. The average pitch (μ) for this user is a note number of about 66.52 and the standard deviation (σ) of about 2.83.

Here, the step including the average pitch (μ) of the user's singing history data is set to step A, and the step B treble, the step C treble, the step D treble, and vice versa are moved away from step A toward the treble direction. Therefore, the case of dividing into step B bass, step C bass, and step D bass will be described as an example. For example, in the case of Fig. 4, step A is applied to the range of μ ± 1.5σ, step B treble to the range of μ + 2σ, step C treble to the range of μ + 3σ, and step B to the range of μ-2σ. The bass and the range up to µ-3σ are referred to as step C bass.

As shown in the table below in Fig. 4, the range of μ ± 1.5σ is a note number ranging from a minimum of about 62.27 to a maximum of about 70.76, and a range of μ ± 2σ ranges from a minimum of about 60.86 to a maximum of about 72.17. Μ ± 3σ ranges from about 58.03 minimum to about 75.00 maximum.

Therefore, all the ranges used in karaoke are represented by integer numbers of note numbers when the music data is MIDI. In this case, pitches 58 and below are stage D bass, pitches 59 through 60 are stage C bass and pitch. Stages are determined so that 61 to 62 are stage B bass, pitch 63 to 70 stage A, pitch 71 to 72 stage B treble, pitch 73 to 75 stage C treble, and pitch 76 or more stage D treble It becomes.

In addition, the determination method of a step is not limited to the method by the statistical method which calculates and calculates the above average pitch and standard deviation, and may be other methods.

For example, FIG. 5 is a specific example of population information in the case of determining a user's stage based on the median pitch and the appearance rate. In this case, first, the median pitch is 66.5, which is the median of the lowest pitch, 59, and the highest pitch, and the sum of the pitch lengths of each pitch is subtracted from the sum of the pitch lengths of all pitches. Steps are determined based on cumulative cumulative rates as they move away in the high or low sound direction.

Specifically, the pitch within which the cumulative emergence rate is within 95% and the cumulative appearance rate exceeds 95% and within 99% and the level B treble or step B bass, the cumulative appearance rate exceeds 99%, reaches the first 100%. The range up to step C treble or step C bass, and the pitch beyond these ranges are referred to as step D treble or step D bass.

Therefore, in the case of Fig. 5, the pitch 57 or less is the step D bass, the pitch 58 to 59 is the step C bass, the pitch 60 to 61 is the step B bass, the pitch 62 to 70 is the step A, and the pitch 71 to 72 is the step Step B is determined so that the high pitch, pitch 73 to 74 is the stage C pitch, and the pitch 75 or more is the stage D pitch.

In the determination method of the said step, although a step is divided by the same value in a high sound direction and a low sound direction, it is not limited to the same value and may be a different value. For example, if the cumulative appearance rate is within 95% of the range A, the cumulative appearance rate in the high direction is greater than 95% and within 99% of the stage B treble, the cumulative appearance rate exceeds 99% and reaches the first pitch up to 100%. Even if the range is set to step C treble and the treble range above step D treble, the range of cumulative appearance exceeds 95% and 97% within the low range. The range up to the pitch may be the step C bass, and the low range beyond it may be the step D bass.

As described above, all sound ranges used in karaoke are divided into a plurality of stages based on the song level of each user, and then a correction coefficient is set for each stage.

As a specific method of setting the correction coefficient, step A is sure to be able to sing, and the correction coefficient is 100%, and the step D treble and step D bass are sure to be unable to sing. Then, the correction coefficients of the step B treble and the step B bass are 75%, the correction coefficients of the step C treble and the step C bass are 50% and the like, and 100% and 0% are set within the limit values.

Human voices are more able to produce higher notes by training, but the lower ones are less likely to come out. In other words, the bass side is hard to sing. Therefore, the correction coefficient is not limited to the same high and low range, but the correction coefficient of the treble portion is made larger than the bass portion. For example, the correction coefficient of the treble bass B is 80%, but the correction coefficient of the bass B bass is 70%, Although the correction coefficient of the step C treble is 60%, the correction coefficient of the step C low treble is 40% or the like, and may be changed in the high and low ranges.

However, the correction coefficient is assumed to decrease as the user's song level moves away from the highest level A in the high or low sound direction. In the above example, the correction coefficient of the step C treble is set to be smaller than the correction coefficient of the step B treble, and similarly, the correction coefficient of the step C bass is smaller than the correction coefficient of the step B bass.

Next, the means for calculating the songable index of the user's target music based on the sum of the sound lengths of each stage in the target music and the correction coefficient of each stage will be described.

For example, if the stage is divided into seven stages of stage A, stage B treble, stage C treble, stage D treble stage B bass, stage C bass, and stage D bass, the specificity of the songable index for the target music is given. The calculation is as follows.

Songable Index = (Sum of Total Musical Length of Step A × Compensation Coefficient + Step B Total Treble Length of Treble Sound × Compensation Coefficient + Step C Total Treble Length of Treble Sound × Compensation Coefficient + Step D Sum of bass notes x Compensation coefficient + step C Sum of bass notes x Compensation coefficient + Step D Sum of bass notes x Compensation coefficient) / (Sum of note A + sum B Sum of treble notes + Step D Sum of treble notes + Step B Sum of bass notes + Step C Sum of bass notes + Step D Sum of bass notes)

In this way, the first calculation means for obtaining the sum of the pitch lengths of the pitches included in the sound ranges of the respective stages of the user in the target piece of music, and the value obtained by the first calculating means are multiplied by a correction coefficient determined for each stage of the user. The user's songable index for each piece of music is divided by dividing the sum of the values of each step obtained by the second calculation means and the second calculation means obtained by the second calculation means by the sum of the values of each step obtained by the first calculation means. Calculate. The calculated information of the songable index is transmitted from the karaoke host apparatus 1 to the karaoke terminal 3 or the user terminal 4 via the communication line 2, and then the display unit of the karaoke terminal 3 or the user terminal 4 is displayed. May be presented to the user.

Fig. 6 is a specific example in the case where the songable index of several target pieces of music is calculated. In this example, the correction factor of step A is 100%, the correction factor of step B treble and step B bass is 75%, the correction factor of step C treble and step C bass is 50%, the correction of step D treble and step D bass The coefficient is 0%, and the songable index is calculated.

In addition, in the rightmost example of Fig. 6, the degree of songability of the target piece of music is indicated by an index indicating the degree of singing ability based on the songability index in order to present the songability index to the user.

For example, if the singability index is 1, the degree of singing is 100%, and if the singability index is more than 0.99 and less than 1, the singing degree is 90%; Singing degree is 80%, songability index is more than 0.97 0.99 If you are sorry, 70% is able to sing, and if you can sing more than 0.96 and less than 0.97, you can sing 60% If the index is 0.95 or more and less than 0.96, 50% of the songs can be singed, and if the songability index is 0.94 or more and less than 0.95, 40% of the songs can be singed, and if the songability index is 0.93 or more and less than 0.94, the song If you can sing 30% and the songability index is more than 0.92 and less than 0.93, you can sing 20%, and if you are more than 0.91 and less than 0.92, you can sing 10% and the songability index Less than 0.91 The degree of singing can be determined to be 0% or the like, and the determination information is transmitted from the karaoke host device 1 to the karaoke terminal 3 or the user terminal 4 via the communication line 2, and the karaoke terminal 3 Or by the display unit of the user terminal 4.

Next, a description will be given of determination means based on the range of the gamut available for use and the range for determining the target music.

First, the range of sound ranges that the user can sing is obtained by multiplying the range of sound levels of each step determined by the step dividing means by the multiplication correction factor determined for each step for all the steps to obtain the range of voices of the user.

For example, the following description will be given in the case where it is divided into five stages: step C low, step B low, step A, step B high and step C high. In this case, the band width of each stage expressed by the difference in the note numbers of MIDI is set to 10 in Step A, 4 in Step B treble, and 4 in Step B bass. Further, the correction coefficients for each stage are 100% for step A, 50% for step B high and step B low, and 0% for step C high and step C low. In this case, when the user's song range is calculated, 10x100% + 4x50% + 4x50% = 14.

Next, from the music data acquired by the target music data acquiring means, the sound range width of the remaining music data, i.e., the decision sound range width, is obtained except for the music data which does not satisfy the predetermined condition in order from the highest sound to the lowest sound.

For example, a case in which a sound range for determination is obtained is assumed with a predetermined condition that the average pitch of the target music is mu, the standard deviation is sigma, and the music data in the range of mu ± 3 sigma is a predetermined condition. In this case, if the highest and lowest sounds of the target piece of music exist together outside the range of μ ± 3σ, music data in the range of the lowest to less than μ-3σ and music data in the range of more than μ + 3σ to the highest note may be Excluded as not satisfied. The difference between the lowest and highest note numbers among the music data after the exclusion, that is, the music data in the range of 占 ± 3 sigma, is obtained as the judgment range.

Next, it is judged whether or not the gamut width of the user's song range is larger than the judging range width, and the determination information is transmitted from the karaoke host device 1 through the communication line 2 to the karaoke terminal 3 or the user terminal ( 4) and present it to the user by the display unit of the karaoke terminal 3 or the user terminal 4.

In addition, the determination is not limited to whether the user's singable range is larger than the range for determination. For example, FIG. 7 is an explanatory diagram of an example of determining whether the target piece of music is singable to the user by using three cases by using the user's singable band width and the range for determining the target piece of music, and whether the target piece of music is singable to the user. In addition, if it is possible, it is determined whether the key is changed to some extent or not. In addition, the length of the dotted line at the top of FIG. 7 indicates the range of sound ranges that the user can sing, and the length of the solid line in the case 1, case 2, and case 3 indicates the range of sound for determining the target music.

The first case is a case where it is judged that the user can sing a song with the same key as long as the range of the song range that the user can sing is larger than the range for the determination of the target piece of music and is within a predetermined range (for example, 0.95 or more). In Fig. 7, Case 1 corresponds to the original key, and the highest and lowest pitches of the range for determining the target music of the target music remain in the range between the step C treble and the step C bass.

Second, when the user's song range is larger than the range for the determination of the target music and the song index is outside the predetermined range (e.g., less than 0.95), it is determined that the key can be changed by indicating how much the key should be changed. to be. In this case, the original key cannot be singed. However, since the width of the range of the user's song is contained in the range of the target music, changing the key makes it possible. In FIG. 7, case 2 corresponds and is lowered into the roughly stage A range.

The third case is a case where it is judged that it is not possible to sing when the range of the user's singable sound range is smaller than the range for the judgment of the target music. In Fig. 7, Case 3 is applicable, and the range for the determination of the target piece of music exceeds the range of the user's song, which indicates that the song is invisible to the user.

In the case of determining, the vocal index is calculated after changing the key when the music of the object to be judged is changed by changing the key, and the calculated information of the vocal index after the key change is transmitted through the communication line (2).

[Example 2]

In this embodiment, the information about the song level of the user used when dividing the user's steps is different from that of the first embodiment, and is divided based on the user's voice data input by the user through the microphone, not the user's song history data. It is. Since other parts are the same as those in the first embodiment, the description is omitted.

Specifically, a plurality of voices are output from the karaoke terminal 3 or the user terminal 4 or the like by the voice of a person or musical instrument output based on sound field data specifying the height and length of each sound in the music. According to the pitch of the pitch, the user speaks and inputs into the microphone. Then, the voice data input through the microphone and the sound data output from the speaker or the headphone are transmitted from the karaoke terminal 3 or the user terminal 4 to the karaoke host device 1.

Next, the central processing unit of the karaoke host apparatus 1 judges the user's singing level based on the result of comparing the received voice data with the sound data, and divides all the ranges used in the karaoke into a plurality of stages. Determine the transliteration of each step of the site.

For example, while the user listens to the sound output from the spurs 21 according to the instruction for vocalization for sampling from the karaoke terminal 3, the user utters with the microphone 20 in accordance with the pitch of the sound heard, and karaoke the voice data. Along with the sound data output from the sputter 21 from the terminal 3, it transmits to the karaoke host apparatus 1 via the communication line 2. As shown in FIG. In addition, the sounds of the plurality of pitches output from the speaker 21 based on the note data for sampling are output in the range up to the highest sound and the lowest sound that the user cannot speak.

The central processing unit of the received karaoke host device 1 compares the pitch of the voice data of the user with the pitch of the sound data output from the speaker 21, and determines whether the difference between the two pitches falls within the range. The song level is judged and all the ranges used in the karaoke are divided into a plurality of stages to determine the range of each stage of the user.

For example, when the pitch of the user's voice data is the same as the pitch of the sound data output from the speaker 21, when the difference is within halftones, and when the difference exceeds the halftone, an example of determining the song level of the user Explain.

Comparing them, the same case is MIDI note numbers 62 to 70, and the difference is within semitones 60 to 61 and 71 to 72 if pitch 59 or less is step C bass, pitch 60 to 61 is step B Determining each step of the user by dividing all the ranges used in karaoke into five so that bass, pitch 62 to 70 are stage A, pitch 71 to 72, stage B treble, and pitch 73 or higher to stage C treble.

In addition, the input means from the microphone 20 in the karaoke terminal 3 is not limited to the method in which the user speaks in accordance with the utterance instruction for sampling from the karaoke terminal 3, and the user uses the karaoke terminal 3. ), The user's voice data uttered when the karaoke piece of music is normally sung and the sound data output from the speaker 21 are transmitted to the karaoke host device 1, and both data may be compared.

It is an object of the present invention to provide a software program for realizing the functions of this embodiment to a system or apparatus, and the computer of the system or apparatus is also achieved by reading out and executing a software program recorded on a storage medium. Same as the case of Example 1.

Example 3

In this embodiment, the information about the song level of the user used when dividing the user's steps is different from that of the first embodiment, and the user inputs the user's input by the input unit of the user terminal 4, not the user's song history data. It divides based on input data by a user. Since other parts are the same as those in the first embodiment, the description is omitted.

Specifically, based on sound data transmitted from the karaoke host device 1 in response to a request from the user terminal 4, the sound of a person output from a speaker or headphones of the user terminal 4, the sound of a musical instrument, or the like. In accordance with the sounds of the plurality of pitches, the user inputs information relating to the utterance level by an input unit such as a keyboard or a mouse of the user terminal 4. Then, the information on the utterance level is transmitted to the karaoke host device 1, and in the central processing unit of the karaoke host device 1, all the sound ranges used in the karaoke are divided into a plurality of steps to determine the sound range of each step of the user. do.

For example, if the user listens to the sound output from the speaker or the headphone of the user terminal 4 according to an input instruction for sampling transmitted from the karaoke host device 1, 1 if the pitch of the corresponding sound can be easily relaxed, 2, and if it is possible to speak, it is 3, and if it is impossible to speak, it inputs using the input part of a keyboard, a mouse, etc. of the user terminal 4, and so on. The sound output from the speaker or the headphones is output in the range up to the highest sound and the lowest sound input by the user incapable of speaking.

In addition, when the user inputs low to high or low to high using the input unit, voice can't be “4”, manages to be able to speak “3”, nearly can be spoken “2”, can be easily spoken, “1”, almost It is possible to input in the order of "2", manageable "3", and "4". Therefore, in the case of an input which does not match this order, an input error check means for making an input error is provided to restrict the input. Therefore, note number 61 of MIDI is almost vocal “2”, 62 to 70 can be freely spoken. “1”, 71 is almost vocal. “2”. Doing so becomes an input error, and the input is restricted.

The information input by the input unit is transmitted from the user terminal 4 to the karaoke host device 1 through the communication circuit 2, and the karaoke is performed based on the input information in the central processing unit of the karaoke host device 1. Dividing all the transliteration used in the step into a plurality of stages to determine the transliteration of each step of the user.

If you entered 1 as a leisurely utterance from MIDI, note numbers 62 to 70, almost 2 utterances as 2, 60 to 61 and 71 to 72, managed to enter 3 as 58, 59 And up to 73 to 74, if less than 57 is inputted as 4 and not more than 75, then pitch 57 or less is stage D bass, pitch 58 to 59 is stage C bass, pitch 60 to 61 stage B Bass, pitches 62 to 70 are stage A, pitches 71 to 72 are stage B treble, stages 73 to 74 are stage C treble, pitch 75 and above are all stages used in karaoke. Determine the transliteration of each step of the user.

It is an object of the present invention to provide a software program for realizing the functions of this embodiment to a system or apparatus, and the computer of the system or apparatus is also achieved by reading out and executing a software program recorded on a storage medium.
