Determine the level. Therefore, the singing level of the entire song can be determined according to the difficulty level of the section that matches the section extraction rule.

  In addition, in the singing level determining apparatus according to the present invention, the singing level determining means determines the average value of the evaluation for each section that matches the section extraction rule as the singing level of the singing data. Therefore, the singing level of the entire song can be determined based on the average difficulty level of the sections that match the section extraction rules.

  In addition, in the singing level determination apparatus according to the present invention, the singing level determination means determines the singing level of the singing data based on the distribution position of the section that matches the section extraction rule. Therefore, the singing level of the entire song can be determined depending on how the sections that match the section extraction rules are distributed.

  In addition, in the singing level determination apparatus according to the present invention, the singing level determination means determines the singing level higher as the sections that match the section extraction rules are dispersed. Therefore, when the sections that match the section extraction rules are dispersed, the singing level can be determined high.

  In addition, in the singing level determining apparatus according to the present invention, the singing level determining means determines the singing level higher as the sections that match the section extraction rule are continuous. Accordingly, when the sections that match the section extraction rules are continuous, the singing level can be determined high.

  In addition, in the singing level determination device according to the present invention, the singing technology symbol extraction means extracts the singing technology symbols while maintaining the order of appearance, and the singing level determination means has a predetermined combination of permutations of the appearing singing technology symbols. If the rules are met, the singing level is determined high. Therefore, the singing level judgment considering the combination of the singing technology symbols can be performed.

This is because the more technical symbols, the more difficult it is.

  In the present specification, the “section extraction rule” corresponds to whether to extract the values of the top 10 section evaluations or to extract the section evaluation values of all sections in the embodiment. However, the present invention is not limited to this, and a predetermined rule may be determined in advance. Further, in the embodiment, the “singing level determination rule” is set to the average of the values of the evaluations for the top 10 intervals, but the values of the evaluation values for the intervals of all the intervals may be averaged. . Of course, the present invention is not limited to this, and a predetermined rule may be determined in advance. That is, it is only necessary to determine in advance a section extraction rule as to which section is to be extracted and an evaluation calculation rule as to how to evaluate from each evaluation of the extracted section. In the embodiment, the “combination rule” corresponds to a rule in the case where two or more singing technique symbols that determine the evaluation by section stored in the combination difficulty table shown in FIG. 4 are consecutive in a predetermined order. .

  The “singing data” includes not only lyrics data but also score data.

[1. (Outline and description of functional blocks)
An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, the functional block diagram of the singing level determination apparatus 1 concerning this invention is shown. As shown in FIG. 1, the singing level determination device 1 includes singing data storage means 3, singing technology symbol extraction means 5, difficulty level table storage means 7, section-specific evaluation determination means 8, and singing level determination means 9. Yes.

  The difficulty level table storage means 7 stores an individual difficulty level table in which singing technology symbols are associated with individual difficulty levels. The singing data storage means 3 stores singing data in which singing technology symbols are added to the singing data. The singing technique symbol extraction means 5 extracts a singing technique symbol existing in the singing data. The section-specific evaluation determining means 8 identifies singing technique symbols other than the breathing mark existing between breathing marks for the extracted singing technique symbols, and the identified breathing marks are stored in the difficulty table storage means 7. Referring to the difficulty table, multiply the individual difficulty level of each type of singing technology symbol by the number of existences, total the individual difficulty level for the singing technology symbol between breathing marks for each breathing interval, and Determine the evaluation by section in the section. The singing level determination means 9 determines the average evaluation for each section obtained by averaging the evaluation for each section for each breathing section as the singing level of the singing data.

  In this way, the singing technology symbols existing in the data are extracted, the singing technology symbols other than the breathing symbol existing between the breathing marks are specified, and the singing technology symbols and their individual difficulty levels are associated with the identified breathing marks. Referring to the difficulty table, the evaluation for each section in each breathing section is determined, and the average evaluation for each section that averages the evaluation for each section is determined as the singing level of the singing data. Therefore, the singing level can be determined in relation to the human voice mechanism of breathing.

[2. Hardware configuration)
The hardware configuration of the singing level determining apparatus 1 shown in FIG. 1 will be described with reference to FIG. FIG. 2 is an example of a hardware configuration in which the singing level determination device 1 is configured using a CPU.

  The singing level determination apparatus 1 includes a CPU 23, a memory 27, a hard disk 26, a monitor 30, a CDD (CD-ROM drive) 25, an input device 28, and a bus line 29. The CPU 23 controls each unit via the bus line 29 according to a program stored in the hard disk 26. As an operating system, for example, WindowsXp (trademark) or the like may be adopted.

  The hard disk 26 stores a program to be described later. This program is read from the CD ROM 25a storing the program via the CDD 25 and installed in the hard disk 26. In addition to the CDROM, a program such as a flexible disk (FD) or an IC card may be installed on a hard disk from a computer-readable recording medium. Furthermore, it may be downloaded using a communication line.

  In the present embodiment, the program stored in the CD-ROM is indirectly executed by the computer by installing the program from the CD-ROM to the hard disk 26. However, the present invention is not limited to this, and the program stored in the CD-ROM may be directly executed from the CDD 25. Note that programs that can be executed by a computer are not only those that can be directly executed by simply installing them, but also those that need to be converted to other forms once (for example, those that have been compressed) are decompressed. Etc.), and those that can be executed in combination with other module parts.

  The hard disk 26 includes a program storage unit 26p, a difficulty level table storage unit 26n, and a lyrics data storage unit 26k. The difficulty level table storage unit 26n stores a symbol-specific difficulty level table shown in FIG. 3 and a combination difficulty level table shown in FIG. In the symbol-specific difficulty level table, technical symbols are stored in association with the individual difficulty levels.

  Each technical symbol shown in FIG. 3 will be briefly described. “Breath” indicates a breathing point. A “short breath” (difficult breath) is a place where the interval between the previous symbol is short and a large amount of breathing needs to be made in a short time, such as after a long tone or non-breath place. “Non-breath” is a point where voice must be passed without breathing. A “long tone” is a point where a singer sings with a note extended or separately from a note. In the present embodiment, one symbol is added per beat, but the present invention is not limited to this. Further, when two or more symbols continue, this is set as an evaluation target (two points when two symbols are continued, three points when three symbols are continued). “Instantaneous power (impact)” is a place that requires instantaneous utterance by the diaphragm in the course of the composition of lyrics and music by relatively judging the technology in one music. “Non-breath” refers to a point where voice is passed without breathing. “Vibrato” is a point that waves the main melody by shaking the muscles from the diaphragm to the vocal cords. “Fake” is the same as Vibrato in that it gives waves to the main melody, but the way it differs. "Fake" is a technique that waves the main melody by shaking the head around the medulla oblongata. Enka's fist, etc. also belongs to "Fake". “Falset” is a utterance point using a back voice. In contrast to the way the earth voice resonates around the body, the falsetet strikes the bone (palate) above the mouth from the throat, sounds from the palate to the skull, and from the top of the skull, It is the sound of the image that sounds. The frequency of the uttered sound itself is high. “Top Falset” is a place where the pitch is quite high even in the back, and it sounds like screaming into a scale. For example, singer “Malaya Carey”, Philip Bailey of group “Earth Wind & Fire”, and singer “Minnie Riparton” who sang Rabinyu are said to be limited in number. “Pitch attention” is a pitch where the chord is applied to the seventh or nineth part of the main melody, the melody line where the author ’s intention should be emphasized, the pitch of a sudden sound, or the continuation of it. It is a difficult part to control. “Rhythm attention” is a difficult part regarding rhythm such as triple rhythm and backing rhythm.

  In the present embodiment, the above singing technique is adopted. However, the present invention is not limited to this technique. For example, other difficulty items such as the number of vocal notes between breaths can be adopted.

  Next, the combination difficulty level table shown in FIG. 4 will be described. In the present embodiment, paying attention to the utterance switching technique, in the case of the following combinations, correspondence information between the score and the symbol combination is stored so that the difficulty level of the section is increased. Specifically, there are 4 points when there is a switch from long tone to vibrato, 7 points when there is a fake and then vibrato switch after vibrato, 8 points when there is a continuous fake, If there was a switch to the falset, 8 points were given. In the present embodiment, the case where there is a switch between the local voice and the falset is a case where the head of the section is not the falset. This determination method will be described later.

  The lyrics data storage unit 26k shown in FIG. 2 will be described. The lyrics data storage unit 26k stores lyrics with singing technology symbols in which the singing technology symbols are described in the lyrics. A specific example is shown in FIG. The lyrics with singing technique symbols are given by understanding what technique is used by a person who can evaluate a song sung by a singer.

[3. flowchart〕
The process in the singing level determination apparatus 1 is demonstrated using FIG. Below, the level determination process in the lyric data with singing technique symbols shown in FIG. 5 will be described as an example. First, the CPU 23 initializes the target section number i (i = 0) (step S1). Next, the CPU 23 specifies the 0th section and extracts existing singing technique symbols (step S3). In this case, as shown in FIG. 7A, six singing technique symbols are extracted. Here, the comma symbol “,” exists between the singing technology symbols when the characters constituting the actual lyrics are between the singing technology symbols. This is for calculating a composite technical point described later. In addition, for the first singing technology symbol, a comma symbol is recorded when the character of the section exists. As will be described later, this is for determining whether or not the singing technique symbol starts from the middle of the section.

  The CPU 23 calculates the score of the 0th section (step S5). In this case, the score by symbol is fake, long tone, long tone, vibrato, vibrato, vibrato. In the present embodiment, when two or more long tones are connected, one point / one is set. Therefore, referring to the table shown in FIG. 3, a total of 13 points are obtained by 4 + 3 + 3 + 3. Further, referring to the table shown in FIG. 4, since there are fake and long tone switching as composite technical points, the total is 17 points.

  The CPU 23 temporarily stores the calculation result (zeroth section: score 17) in the memory.

  The CPU 23 determines whether or not the process has been completed up to the last section (step S7). In this case, since the final section has not been completed, the target section number i is incremented (step S8), and the processing from step S3 is performed.

  In this case, the CPU 23 specifies the first section and extracts existing singing technology symbols (step S3). In this case, as shown in FIG. 7B, six singing technique symbols are extracted. The CPU 23 calculates the score of the first section (step S5). In this case, the total score by symbol is 5 + 3 + 3 = 11 points. The combined technical point is 8 points by switching between the local voice and the falset. Therefore, the total is 19 points. The CPU 23 temporarily stores the calculation result in the memory.

  Similarly, symbols as shown in FIGS. 7C, 7D, 7E, and 7F are extracted, and the second section: 11 points, the third section: 0 points, the fourth section: 0 points, and the fifth section. : 31 points, ... and score for each section.

  In the second section shown in FIG. 7C, there is no comma symbol before the singing technique symbol “Falset”. Therefore, it is judged that the voice is uttered from the beginning of the section. On the other hand, in the first section shown in FIG. 7B and the eighth section shown in FIG. 7I, there is a comma symbol before the singing technique symbol “Falset”. Therefore, it is determined that there is a switch between the local voice and the falset in the middle of the section. In the first section, there is a comma symbol between the singing technology symbols “long tone” and “vibrato”. Therefore, it can be determined that there is no utterance switching shown in FIG.

  If the CPU 23 determines in step S7 that the last section has been completed, it calculates the singing level (step S9). In this embodiment, the rule of extracting the top 20 scoring sections among all sections is adopted as the section extraction rule, and the average of these is calculated as the singing level of the song. In this way, by determining the singing level by a predetermined upper section, the singing level of the entire song can be determined by the difficult section.

  FIG. 8 shows an example of lyrics with singing technology symbols when different singers sing the same song. In this case, as in the above embodiment, singing technique symbols as shown in FIG. 9 are extracted, and the score for each section is calculated. In this case, compared to the case shown in FIG. 7, the number of extracted singing technique symbols is small, and the singing level is calculated based on the score for each section. Thus, when different singers sing the same song, the singing level varies depending on the added singing technology symbols and combinations thereof.

[4. Other embodiments]
In the above embodiment, the singing level of the song with the singing technology symbol is determined. By performing this singing level determination, for example, by adding a singing symbol when a certain singer sings a certain tune, and causing this apparatus to calculate, the degree of difficulty of the karaoke song can be provided. This difficulty level can also be adopted as a selection judgment element when singing.

  Note that, instead of extracting a predetermined upper section, scores for all sections of all sections may be averaged. As processing in this case, all singing technique symbols may be extracted and divided by the number of existing breaths without obtaining a score for each section. Thus, it is also possible to determine the singer's singing level based on the section evaluation for each breathing section.

  In addition, the singing level may be determined based on the distribution position of the section that matches the section extraction rule, instead of the average value of the section evaluation of the section that matches the section extraction rule. For example, the singing level can be determined to be higher as the intervals that match the interval extraction rule are dispersed, or the singing level can be determined to be higher as the intervals that match the interval extraction rule are continuous. .

  In the present embodiment, determination is made based on whether or not the singing technique symbols shown in the tables shown in FIGS. 3 and 4 are present in the song. However, this singing technology symbol is an example, and other singing technology symbols may be adopted.

  In the present embodiment, the singing level is determined from the existing singing technology symbols using both the single difficulty level and the difficulty level by the combination. However, the determination may be made by only one of them.

  In this embodiment, such a calculation is performed by a computer, but a human may perform the calculation. Even in this case, it is possible to determine that the singing level is high when the singing technology symbol existing between the breaths is high, and low when it is low, so the air inhaled by the breath is released outside the body. Since the singing level can be determined based on the human vocalization mechanism that produces various sounds depending on the vocal cords of the time, objective singing level determination is possible.

  In the above embodiment, the singing level corresponding to the presence of the singing technology symbol other than the breath between the breaths is calculated. However, a certain section is not a normal breath but a short breath existing at the end of the section. May be added as the evaluation value of the section, only a short breath. This is because a short breath is a singing technique with a high singing level that may be judged as one of the singing techniques.

  In the above embodiment, the case where the lyrics data is taken as an example of the singing data has been described, but it may be musical score data. An example of such notation is shown in FIG. In this way, the present invention can be similarly applied to musical score data to which a singing technique symbol is added. Moreover, although the case where the singing technical symbol was added between the notes was described in FIG. 10, any position may be added.

  In the above embodiment, the score corresponding to the singing technology symbol other than the breath between the breaths is calculated, but the score corresponding to the number of vocal notes between the breaths is obtained for each section, and the score for each section is calculated. From the above, the entire singing level may be calculated.

  In the above embodiment, the singing technology symbols are extracted once from the singing data, and the difficulty level is calculated for each section after only these singing technology symbols, but the singing technology symbols existing in the singing data are detected as they are. The difficulty level may be directly calculated for each section. That is, the above extraction is a concept including a technique for detecting such a singing technique symbol as it is.

  In this embodiment, in order to realize the function shown in FIG. 1, a CPU is used and this is realized by software. However, some or all of them may be realized by hardware such as a logic circuit.

  In addition, you may make it make an operating system (OS) process a part of program further.
