Description

  The present invention relates to a singing scoring system, and in particular, sets a scoring section that is subject to singing scoring so that it is shorter than the singing time of each word that is the lyrics of karaoke music, and in each scoring section The present invention relates to a singing scoring system that compares a singing voice signal input from a microphone with scoring reference data to calculate a singing scoring value.

  The currently popular karaoke system has a singing scoring function that compares a singing voice signal input from a microphone and scoring reference data to calculate a singing scoring value. The technique regarding such a singing scoring function is described in Patent Document 1, for example.

  In the karaoke apparatus described in Patent Document 1, a karaoke performance is performed by a sequencer reading out data for karaoke performance and inputting it into a musical sound generator. The karaoke singer sings along with the karaoke performance, and the singing voice signal is input to the amplifier via the microphone and also to the A / D converter, and is converted into digital data.

  Then, the data extraction unit extracts pitch data and volume data from the digitized singing voice signal, and inputs the extracted pitch data and volume data (singing voice) to the comparison unit. The sequencer reads a guide melody, which is comparison data, in parallel with the karaoke performance data and inputs it to the comparison unit. The comparison unit compares the extracted pitch data, volume data, and guide melody, and evaluates the skill of the singer's singing.

Japanese Patent Laid-Open No. 10-69216

  As described above, the singing score value can be calculated by comparing the singing voice signal input from the microphone and digitally converted by the A / D converter with the singing score reference data such as a guide melody. However, in particular, a grading section that is subject to singing is set so that it is shorter than the singing time of each word that is the lyrics of the karaoke music, and in each scoring section, the singing voice signal input from the microphone and In a singing scoring system that calculates singing scoring values by comparing with scoring reference data, pitch data (pitch data) may not be extracted depending on the type of words in the lyrics.

  And, in the scoring section where pitch data (pitch data) cannot be extracted, the singing scoring value becomes low because the data compared with the scoring reference data cannot be extracted even though the singer sings well. There was a problem that accurate singing could not be performed.

  In other words, in the pitch detection method used in the current karaoke system, the pitch cannot be detected in principle for consonant parts (s, t, k, etc.) in words included in the lyrics. Further, the time length of sound generation differs depending on the type of consonant. Specifically, when “su” and “ki” having the same length are compared, the consonant part “s” in “su” has a longer pronunciation time than the consonant part “k” in “ki”. Therefore, if pitch detection is performed for each scoring interval, the time required for the consonant part “s” to occupy the pronunciation of the sub-line becomes longer, and the accuracy of pitch detection is lower than that of the pronunciation of the c-line. On the other hand, in the pronunciation of the K line, since the time occupied by the consonant part “k” in the section is short, the accuracy of pitch detection hardly decreases.

  Referring to the drawings, the length of the consonant part when pronounced "su" and "ki", the analysis result of the frequency characteristics by FFT of the consonant "s" in "su" (hereinafter abbreviated as FFT, the same applies to the drawings) ) And the vowel “u”, the FFT of the consonant “k” and the FFT of the vowel “i” in “ki”. In normal singing, the length of “s” in the pronunciation of the consonant portion, that is, “su”, and the length of “k” in the pronunciation of “ki” may be considered to be substantially constant. On the other hand, regarding the length of “u” in the pronunciation of the vowel part, that is, “i” in the pronunciation of “su”, the entire pronunciation such as “su” and “ki” is sung short or long. It will change. 6 is an explanatory diagram showing the length of the consonant in the pronunciation of “su”, FIG. 7 is an explanatory diagram showing the FFT of the consonant “s”, and FIG. 8 is an explanatory diagram showing the FFT of the vowel “u”. 9 is an explanatory diagram showing the length of the consonant in the pronunciation of “ki”, FIG. 10 is an explanatory diagram showing the FFT of the consonant “k”, and FIG. 11 is an explanatory diagram showing the FFT of the vowel “i”.

  As shown in FIG. 6, when “su” is pronounced, the pronunciation of the consonant “s” continues for about 110 msec. Further, as shown in FIG. 7, when the consonant “s” is pronounced, a clear fundamental tone or harmonic sequence is not recognized, and it is difficult to detect the pitch. On the other hand, as shown in FIG. 8, when the vowel “u” is pronounced, it includes a fundamental tone having a relatively high level at a frequency of about 310 Hz and a harmonic sequence having a frequency that is substantially an integral multiple of the fundamental tone. Can be detected. As described above, in the pronunciation of the sub-line (for example, the pronunciation of “su”), since the time occupied by the consonant part “s” is long in the scoring interval, accurate pitch detection cannot be performed. Therefore, in order to increase the accuracy of the scoring in the scoring section including the voice of the bank, it is necessary to devise the scoring process.

  On the other hand, as shown in FIG. 9, when “ki” is pronounced, the sounding part of the consonant “k” is about 25 msec, which is less than a quarter of the sounding part of the consonant “s”. . Also, as shown in FIG. 10, when the consonant “k” is pronounced, a clear fundamental tone or harmonic sequence is not recognized, and it is difficult to detect the pitch. On the other hand, as shown in FIG. 11, when the vowel “i” is pronounced, it includes a fundamental tone having a frequency of about 300 Hz and a relatively high level, and a harmonic sequence having a frequency that is substantially an integral multiple of the fundamental tone. Can be detected. In this way, in the pronunciation of a ka line (for example, the pronunciation of “ki”), the time occupied by the consonant part “k” in the scoring section of a predetermined time length is extremely short, and therefore pitch detection is performed on the consonant part “k”. Even if it is not possible, it is possible to detect the pitch necessary for singing in the vowel part “i”. Therefore, the accuracy of the scoring process does not extremely decrease in the scoring section including the voice of the mosquito line.

  As is clear from FIG. 6 to FIG. 11, the peak of the integer overtone appears clearly in the vowel part in both cases of the S line and the C line, whereas the pitch can be detected with the fundamental tone. In the consonant part, there is no peak even if it is attempted to detect the pitch in the frequency range of the fundamental tone, so pitch detection (measurement of one wavelength) cannot be performed. Furthermore, since the pronunciation time of the consonant part “k” is shorter in the ca line than in the sa line, the pitch detection can be performed while ignoring the consonant part “k”.

  The present invention has been proposed in view of the above-described circumstances, and accurate singing is possible even when there is a scoring section in which pitch data (pitch data) cannot be extracted according to the type of consonant included in the words of the lyrics. An object of the present invention is to provide a singing scoring system capable of scoring.

  The singing scoring system of the present invention has been proposed in view of the above-described circumstances, and has the following characteristic points. That is, the singing scoring system of the present invention sets a scoring section that is the subject of singing scoring so that it is shorter than the singing time of each word that is the lyrics of karaoke music, and inputs from the microphone in each scoring section In the singing scoring system that calculates the singing scoring value by comparing the singing voice signal and scoring reference data, the scoring system includes scoring processing means for scoring differently depending on the type of the consonant for the scoring section including the consonant It is characterized by this.

  Further, in the singing scoring system of the present invention, the scoring processing means has a pitch detecting function capable of detecting the pitch of vowels included in each scoring section, which is a pitch detecting function of singing voice for use in scoring, and a consonant It is preferable to perform different scoring processes according to the time length of the consonant for the scoring section including.

  Moreover, when it has the pitch detection function of a singing voice, a scoring process means, the scoring value of the scoring area which does not contain the consonant of other predetermined time or more, the singing scoring value of the scoring area containing the consonant more than predetermined time length It can be configured to replace

  Moreover, when it has the pitch detection function of a singing voice, a scoring process means can be comprised so that it may not set as the scoring area used as scoring object about the scoring area containing the consonant more than predetermined time length.

  Moreover, when it has the pitch detection function of a singing voice, a scoring process means, the scoring value of the scoring area which does not contain the consonant of other predetermined time or more, the singing scoring value of the scoring area containing the consonant more than predetermined time length It is possible to make a calculation by interpolation based on the above.

  Moreover, when it has the pitch detection function of singing voice, the scoring processing means calculates the singing score value of the scoring section including the consonant longer than the predetermined time length based on the ratio of the singing part other than the consonant and the scoring value. It can be configured to do so.

  In the singing scoring system having such a configuration, when a user sings along with the performance of the karaoke music, the singing voice signal input from the microphone is digitally converted by the A / D converter, and becomes a singing scoring target. Generate scoring target data. Then, the grading processing means compares the grading target data with the grading reference data for each predetermined singing grading section to calculate the singing grading value.

  At this time, the scoring processing means performs different scoring processing on the scoring section including the consonant depending on the type of the consonant. That is, when the scoring means has a pitch detection function for singing voice for use in scoring, the scoring value of a scoring section including consonants longer than a predetermined time length is not included in the scoring section including other consonants longer than a predetermined time. Replace with the scoring value (for example, the previous or next scoring interval). Moreover, you may exclude from the scoring area used as scoring object about the scoring area containing the consonant more than predetermined time length. Moreover, you may interpolate the scoring value for the scoring area containing the consonant more than predetermined time length based on the scoring value for another scoring area. Further, for a scoring section including consonants that are longer than a predetermined time length, the scoring value of the scoring section may be calculated based on the ratio of the singing part other than the consonant and the scoring value.

  According to the singing scoring system of the present invention, the pitch data (pitch data) cannot be extracted for the scoring section including the consonant by performing different scoring processes according to the type of the consonant for the scoring section including the consonant. Even so, it is possible to accurately score the singing.

  In particular, if you set a scoring section that is subject to singing so that it is shorter than the singing time of each word that is the lyrics of karaoke music, pitch data (pitch data) may not be extracted. In the singing scoring system of the invention, even if such a singing scoring section exists, accurate singing scoring can be performed.

In addition, the scoring section containing the consonant more than predetermined time length can be specified based on lyrics rendering data. That is, the lyric rendering data and each scoring section are synchronized, and if the lyric rendering data includes a consonant longer than a predetermined time such as “s” or “h”, the lyric rendering is performed. The scoring section corresponding to the data can be a scoring section including consonants longer than a predetermined time length.

<Scoring process (Example 1)>
With reference to FIG. 2, Example 1 of the scoring process in the scoring means 38 will be described. Example 1 of scoring processing uses a scoring value based on a pitch detection result in a scoring section other than the scoring section without performing scoring based on the pitch detection result for a scoring section including a consonant longer than a predetermined time length. The scoring value of the scoring section is replaced or interpolated.

  That is, as shown in FIG. 2, when there is a scoring section including consonants longer than a predetermined time length, such as “s” and “h”, singing scoring is not performed for the scoring section. Then, using the scoring value based on the pitch detection result in the scoring section before and after the scoring section, the scoring value of the scoring section is replaced or interpolated.

  In the example shown in FIG. 2, in the scoring section including the consonant “s” and the consonant “h” that are equal to or longer than the predetermined time length, the singing scoring is not performed, and the scoring value in the scoring section of each section before and after the scoring section is sandwiched. Instead of the average value or standard deviation, etc., as the scoring value of the scoring section (scoring section including consonant “s” and consonant “h”) where the singing scoring is not performed. Singing is performed.

  Note that the scoring value of a scoring section containing consonants longer than a predetermined time length is replaced by a scoring section one section before the scoring section, a scoring section after the first section, and one section before and after the scoring section. The scoring section, and scoring sections of a plurality of sections before and after the scoring section, etc. can be changed as appropriate. In addition, when the immediately preceding or immediately following scoring section includes a consonant of a predetermined time length or more, the scoring value of the scoring section other than the scoring section is set as the alternative scoring value.

  Specifically, as shown in FIG. 2, the section (1) includes a consonant “s” that is equal to or longer than a predetermined time length, and thus is not scored. In this section (1), since there is no previous section, 80 points which are the scoring values of the section (2) which is the subsequent section are replaced with scoring values of the section (1). In the section (3), the consonant “k” is included. However, since the consonant “k” has a short pronunciation time and can sufficiently detect the pitch in a portion other than the consonant “k”, the actual scoring value is obtained. 75 points are set as the scoring value of the section (3). In section (5), scoring is not performed because consonant “h” longer than a predetermined time length is included. Since this section (5) has preceding and following sections, an average value of 78 points, which are the scoring value of section (4), and 82 points, which is the scoring value of section (6), is taken as 80 points (5 ) Is interpolated as the scoring value.

<Scoring process (Example 2)>
With reference to FIG. 3, Example 2 of the scoring process in the scoring means 38 will be described. In the second embodiment of the scoring process, a scoring section including a consonant having a predetermined time length or more is not set as a scoring section to be scoring.

  That is, as shown in FIG. 3, for example, if there is a scoring section including consonants longer than a predetermined time length, such as “s” and “h”, singing scoring is not performed for the scoring section. And based on the scoring value of scoring sections other than the said scoring section, the singing scoring for every predetermined scoring section and the singing scoring of the whole music are performed.

  In the example shown in FIG. 3, singing scoring is not performed in a scoring section including a consonant “s” and a consonant “h” that are equal to or longer than a predetermined time length, and based on scoring values in scoring sections other than the scoring section. Singing for each grading section and singing for the entire song.

  Specifically, as shown in FIG. 3, the section (1) includes a consonant “s” that is equal to or longer than a predetermined time length, so even if scoring is performed, the scoring value is reflected in the total scoring result. I won't let you. Similar to the first embodiment, scoring may not be performed for the section (1). In the section (3), the consonant “k” is included. However, since the consonant “k” has a short pronunciation time and can sufficiently detect the pitch in a portion other than the consonant “k”, the actual scoring value is obtained. The score of 75 is used as the score of the section (3), and the score is reflected in the overall score. In addition, in the section (5), since the consonant “h” having a predetermined time length or more is included, even if scoring is performed, the scoring value is not reflected in the total scoring result. In the section (5), scoring may not be performed as in the section (1).

<Scoring process (Example 3)>
With reference to FIG. 4, a third embodiment of the scoring process in the scoring processing means 38 will be described. In the third embodiment of the scoring process, the scoring value of the scoring section is calculated based on the ratio of the singing part other than the consonant and the scoring value for the scoring section including the consonant longer than the predetermined time length. is there.

  As shown in FIG. 4, when there is a scoring section including consonants longer than a predetermined time length, such as “s” and “h”, the following scoring process is performed on the scoring section. That is, in the scoring section, the time ratio between the consonant singing part longer than the predetermined time length and the singing part capable of performing pitch detection is calculated. The perfect score according to the ratio is given. On the other hand, in the singing part where the pitch can be detected, the scoring value of the scoring section is calculated based on the time ratio and scoring value. And the scoring value of the singing part of the consonant calculated according to the time ratio and the scoring value of the other singing part are added to obtain the scoring value of the scoring section including the consonant longer than the predetermined time length.

  In the example shown in FIG. 4, in a scoring section including a consonant “s” and a consonant “h” having a predetermined time length or longer, a singing portion including the consonant “s” and the consonant “h” has a predetermined time length or more. The time ratio between the singing part of the consonant and the singing part where the pitch can be detected is calculated, and the scoring values are calculated and added together. Thereby, a substantially accurate singing score can be performed also about the scoring area containing consonant "s" and consonant "h" more than predetermined time length.

  Specifically, as shown in FIG. 4, the section (1) includes a consonant “s” that is equal to or longer than a predetermined time length, so the singing portion of the consonant “s” corresponds to the time ratio. A perfect score is given. Further, in the section (1), scoring is performed for parts other than the singing part including the consonant “s”, and the scoring value of the singing part is calculated according to the time ratio. In the example shown in FIG. 4, the singing part of the consonant “s” is 30% of the section (1), and the part other than the singing part including the consonant “s” is 70% of the section (1). The scoring value is 60 points. Therefore, the scoring value in the section (1) is {100 points × (30/100)} + {60 points × (70/100)} = 72 points.

  In the section (3), the consonant “k” is included. However, since the consonant “k” has a short pronunciation time and can sufficiently detect the pitch in a portion other than the consonant “k”, the actual scoring value is obtained. 75 points are set as the scoring value of the section (3).

  Further, since the section (5) includes the consonant “h” that is equal to or longer than the predetermined time length, the singing portion of the consonant “h” is given a perfect score according to the time ratio. Further, in the section (5), scoring is performed for parts other than the singing part including the consonant “h”, and the scoring value of the singing part is calculated according to the time ratio. In the example shown in FIG. 4, the singing part of the consonant “h” is 40% of the section (1), and the part other than the singing part including the consonant “h” is 60% of the section (5). The scoring value is 55 points. Therefore, the scoring value in the section (5) is {100 points × (40/100)} + {55 points × (60/100)} = 73 points.

<Scoring process (Example 4)>
With reference to FIG. 5, a fourth embodiment of scoring processing in the scoring processing means 38 will be described. Example 4 of the scoring process is that the scoring value of the scoring section is calculated based on the ratio of the singing part other than the consonant and the scoring value for the scoring section including the consonant of the predetermined time length or more. This is the same as in Example 3.

  Only the scoring value calculation method different from that in the third embodiment will be described below. In Example 4, as shown in FIG. 5, the section (1) includes a consonant “s” longer than a predetermined time length, and therefore, the singing part of the consonant “s” cannot be scored. The corrected scoring value is adopted. That is, in section (1), scoring other than the singing part containing the consonant “s” is performed, and the scoring value of the singing part is calculated according to the time ratio. Then, in the singing part including the consonant “s”, the scoring value of the singing part is calculated according to the time ratio of the singing part of the consonant “s” using the scoring value other than the singing part of the consonant “s”. To do. In the example shown in FIG. 5, the singing part of the consonant “s” is 30% of the section (1), and the part other than the singing part including the consonant “s” is 70% of the section (1). The scoring value other than the included singing part is 52 points. Therefore, the corrected scoring value in the section (1) is (estimated scoring value of consonant part = 22 points) + (actual scoring value other than consonant part = 52 points) = 74 points.

  In the section (3), the consonant “k” is included. However, since the consonant “k” has a short pronunciation time and can sufficiently detect the pitch in a portion other than the consonant “k”, the actual scoring value is obtained. 75 points are set as the scoring value of the section (3).

  Further, in the section (5), scoring is performed for portions other than the singing portion including the consonant “h” longer than the predetermined time length, and the scoring value of the singing portion is calculated according to the time ratio. And, in the singing part including the consonant “h”, the scoring value of the singing part is calculated according to the time ratio of the singing part of the consonant “h” using the scoring value other than the singing part of the consonant “h”. To do. In the example shown in FIG. 5, the singing part of the consonant “h” is 40% of the section (1), and the part other than the singing part including the consonant “h” is 60% of the section (1). The scoring value other than the included singing part is 45 points. Therefore, the corrected scoring value in the section (5) is (estimated scoring value of consonant part = 30 points) + (actual scoring value other than consonant part = 45 points) = 75 points.
