  Some karaoke devices have a function of performing song evaluation by scoring songs. By using such a song evaluation function, it is possible to objectively judge the user's singing ability. As mentioned above, people who are used to karaoke can fully demonstrate their abilities, but untrained people may be unable to exert their abilities with tension. In such a case, it is expected that the singing evaluation of an unfamiliar person will be lower than his or her ability. Users who are hit by low song ratings are likely to be more reluctant to sing in front of the public and to fall into a vicious circle of tensions again at the opportunity to sing.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to suppress that the evaluation of singing by a user who sings nervously becomes a low evaluation.

The present invention is intended to solve such problems, and is characterized in that the following configuration is adopted.
Performance processing for performing a performance based on performance information corresponding to the music;
A detection process for detecting a tension state of a user singing during the performance process period;
Singing evaluation processing that calculates singing evaluation information based on singing voice input from a microphone and performance information to be played;
A correction process for correcting song evaluation information so that the evaluation becomes high when the tension state detected in the detection process is high;
Performing notification processing for notifying the song evaluation information corrected by the correction processing.

Furthermore, in the karaoke apparatus according to the present invention,
The detection processing is characterized in that a tension state is detected based on a singing voice of the user.

Furthermore, the karaoke apparatus according to the present invention is
The present invention is characterized in that the tension state is detected based on the length of time in which the singing voice is in a predetermined state during the playing time of the first music.

Furthermore, the karaoke apparatus according to the present invention is
The correction degree of the song evaluation information is changed according to the degree of the tension state detected in the detection process.

The karaoke program according to the present invention is
Performance processing that plays based on performance information,
A detection process for detecting a tension state of a user singing during the performance process period;
Singing evaluation processing that calculates singing evaluation information based on singing voice input from a microphone and performance information to be played;
A correction process for correcting song evaluation information so that the evaluation becomes high when the tension state detected in the detection process is high;
The information processing apparatus is caused to execute notification processing of notifying the song evaluation information subjected to the correction processing.

  According to the karaoke apparatus and the program for karaoke according to the present invention, it is possible to suppress that the evaluation of singing by the user who sings nervously becomes a low evaluation. By not lowering the evaluation also for users who are nervous and sing, it is possible to give confidence in singing, to improve the positivity for karaoke, and thus to expand the karaoke population.

  Furthermore, the present invention is characterized in that the tension state is detected based on the user's singing voice. According to such a configuration, there is no need to add a new configuration, such as providing a means for detecting tremor due to tension in the microphone, and it becomes possible to detect a tension state using an existing configuration.

  Furthermore, according to the present invention, the tension state is determined and detected based on the length of time in which the singing voice is in the predetermined state during the performance of one music piece. According to such a configuration, it is possible to easily determine the tension state by counting the time length which is the predetermined state. Furthermore, the tension state may be determined at a ratio of time during which the singing voice is in a predetermined state with respect to the singing period of one music piece. According to such a configuration, it is possible to improve the accuracy of the tension state, and it is also possible to easily calculate the degree of tension.

  Furthermore, according to the present invention, the degree of correction of the song evaluation information is changed in accordance with the detected degree of tension. According to such a configuration, in the case of a severe tension state, the singing evaluation is increased significantly, and in the case of a mild tension state, the tension evaluation is appropriately reduced by raising the singing evaluation slightly. It becomes possible to notify a good song evaluation.

On the other hand, it is possible to give various instructions such as music reservation.

  The music confirmation screen of this embodiment is shown in FIG. The karaoke system of this embodiment can be used by a plurality of users logging in simultaneously. By logging in, users can receive various services using their own user information. As services that the user can receive, there are favorite music registered by the user, history, music search using favorite artist (singer), or recommendation of music according to the attribute of the user. In the upper part of the music confirmation screen shown in FIG. 2, information on the user who has logged in to the karaoke system is displayed. In the login user column 103, partial images 103a to 103e (a face portion in the present embodiment) of users who are logged in to the karaoke system are displayed. The user whose background is highlighted (white) at the right end of the login user column 103 is the active user 103e (in this example, Mr. A), and the service for the active user 103e, that is, the user information of the active user 103e. The service using is being executed. The switching of the active user can be performed by operating the user switching button 101. Also, a user who is not registered as a user can use the karaoke system as a guest user by operating the guest button 102.

  When a song is selected as the active user, the user confirms the details such as the song name, the singer's name, and the singing out on the song confirmation screen to see if the song to be reserved is correct. A pitch setting field 105 is provided on the music confirmation screen of the present embodiment. The pitch setting section 105 is a setting section for adjusting the pitch so that the user can easily sing when playing, and by operating the change button displayed at the lower right of the pitch setting section 105, the pitch setting section 105 is used. A subscreen (not shown) for setting is displayed, and it is possible to set a pitch setting value for the music piece to be reserved.

  On the music confirmation screen, the user who confirms that the music to be sung, operates the reservation button 106 to confirm the music reservation. When music is reserved using remote control device 1, the remote control device 1 transmits reservation information to karaoke apparatus 2. FIG. 3A shows a data structure of reservation information. The reservation information includes the music ID for identifying the reserved music, the user ID for identifying the user who made the reservation (active user), and the pitch setting value changed using the pitch setting field 105 of the music confirmation screen. include. The karaoke apparatus 2 sequentially stores the received reservation information in the reservation table managed by the memory 27 of the karaoke apparatus 2 and executes the music reproduction process.

  FIG. 4 and FIG. 5 are flowcharts showing the music reproduction process of this embodiment. Circles “1” in FIGS. 4 and 5 indicate the connection between the two flows. The karaoke apparatus 2 checks the reservation table (S101), and when it is determined that there is a music to be reproduced next (S102: Yes), the music information corresponding to the music ID is read and the performance is started ( S103).

  FIG. 3B is a diagram showing a data configuration of music information. The music information includes meta information, which is various information related to the music information, and actual information for executing various processes such as performance and display of lyrics. The meta information includes a song ID for identifying song information, a song name, a singer name, a lyricist name, a composer name, and singing section information. The singing section information is information corresponding to the time progression of the performance information, and is information that enables the user to identify a section (singing section) to be sung. In the present embodiment, at the time of reproducing the music, this singing section information is used to extract a feature amount for performing a singing evaluation from the singing voice sung in the singing section.

  The actual information of the music information includes performance information, lyric information, and reference pitch information. The performance information is information for playing the accompaniment sound of karaoke, which includes control information for an electronic musical instrument based on the MIDI standard, or compressed audio information obtained by recording an actual performance. The lyric information is information that is displayed in synchronization with the performance information for song assistance, and may be configured to change the color of the displayed lyrics in synchronization with the performance. The reference pitch information is information that defines a melody to be sung, and is used in the song evaluation process (scoring) in the present embodiment. The reference pitch information may be included in the performance information.

  When the performance is started based on the performance information in the music information (S103), extraction of the feature amount of the singing voice input from the microphones 44a and 44b is performed in order to evaluate the singing. In this embodiment, during reproduction of the music, by extracting the feature amount of the singing voice only for the singing section, voice and noise unrelated to singing are eliminated, and the accuracy of the singing evaluation is improved.

  First, initialization of the current performance time t (S104) and initialization of the acquired number n of the fundamental frequency f0, which is the feature of the singing voice, are performed (S105). The current playing time t is incremented (S107) every time the playing time has elapsed (S106: Yes) after a predetermined time (10 ms in this example) has elapsed. Then, the current performance time t is compared with the singing section information of the music information to determine whether the current performance time t is a singing section (S108). If the current performance time t is a singing section (S108: Yes) The singing voices input from the microphones 44a and 44b are analyzed, the fundamental frequency f0 is extracted, and is stored in the buffer in the memory 27 in association with the current performance time t (S109). At this time, the number n of acquired fundamental frequencies f0 is incremented (S110). On the other hand, when the current performance time t is not the singing section (S108: No), the basic frequency f0 is not stored in the buffer and the next current performance time is waited.

  By repeatedly executing the processing of S106 to S110 until the performance of the music ends (S111: Yes), the feature amount of the singing in which the current performance time t and the fundamental frequency f0 correspond to each other is stored in the buffer for the singing section of the music Stored. When the performance of the music is finished (S111: Yes), song evaluation based on the feature amount of the song stored in the buffer is performed. First, in the present embodiment, it is determined whether or not the acquired number n of the fundamental frequency f0, which is a feature amount of song evaluation, is larger than a predetermined number L (S112). This determination is a process for confirming whether or not the fundamental frequency f0 which is the minimum necessary for song evaluation is acquired. When the reproduction of music is interrupted halfway, singing evaluation may be performed with a small number of feature amounts, which may result in good singing evaluation. In the present embodiment, it is prevented that the fraud is performed using such a specification. When the feature amount of the song (the number of acquired fundamental frequencies f0) is smaller than L (S112: No), the karaoke apparatus 2 notifies the monitor 41 that the song evaluation could not be performed (S118).

  On the other hand, when the feature amount of the song (the number of acquired fundamental frequencies f0) is larger than L (S112: Yes), the mode set in the karaoke apparatus 2 is detected (S113). The karaoke apparatus 2 of the present embodiment can be switched to a standard mode in which normal song evaluation is performed and a tension consideration mode in which the tension of the user who sings is considered. The mode can be switched using input means such as the touch panel monitor 33 of the karaoke apparatus 2 or the touch panel monitor 11 of the remote control device 1. In this tension consideration mode, when the tension state of the user who sings is high, correction is performed so that the song evaluation becomes high. By using the tension consideration mode, it is possible to present a good singing evaluation in consideration of tension to a user who is unfamiliar with singing in public.

  In the present embodiment, switching of the mode is either the standard mode or the tension consideration mode, but the standard mode and the tension consideration mode may be set for each user. For example, in a night shop such as a snack, a customer who is not familiar with singing is set in the tension consideration mode, and a customer who can sing sufficiently is set in the standard mode so that the mode is automatically set for each user who sings. It is possible to switch. The switching of the mode is performed by using the user ID included in the reservation information to determine which mode the user is set to.

  When it is determined in the mode determination that the mode is the standard mode (S113: standard), the song evaluation process (S117) is executed. This song evaluation process (S117) is a form which does not consider the tension state of the user, and contrasts the feature quantity of the song (the fundamental frequency f0 in this embodiment) with the basic pitch information of the played music. Is a process of calculating song evaluation information. As a result of song evaluation, it is possible to present by a graded value or ranking. In this embodiment, the score is calculated for five items in the song, and the total score is used as a result of the song evaluation. The result of the song evaluation calculated in the song evaluation process (S117) is notified to the user in the form of being displayed on the monitor 41 or the like.

  FIG. 10A shows a notification example of the result of song evaluation when the standard mode is used. Here, the notification is made by displaying the result on the monitor 41. On the screen displaying the results, the singer name of the song sung, the song name, the user name of the user who sung, the scoring value calculated for the 5 items (pitch, stability, long tone, intonation, technique), 5 items The total score which is the sum of the scoring value of is displayed. Also, using the form of the radar chart, the scoring values of the five items are displayed. By watching the result of the song evaluation after singing, it is possible for the user who has sung to confirm his / her singing ability.

  On the other hand, when it is determined in the mode determination that the mode is the tension consideration mode (S113: tension consideration), song evaluation in consideration of the tension state is performed. Here, when the tension state is high, the song evaluation information is calculated by correcting the song evaluation to be higher than that in the standard mode. In the present embodiment, first, the process A for detecting the tension state of the user is executed (S200). In the present embodiment, the tension state is detected based on the user's singing voice. If you sing under tension, it will appear as a tremor of the singing voice. It is possible to detect tension based on the tremor of the singing voice. On the other hand, vibrato, which is a technique for shaking voices in singing, is known. Here, in order to distinguish tension and vibrato, the characteristics of both are used.

  FIG. 9 is a figure for demonstrating the feature of the tremor of the voice by vibrato and tension. 9 (A) to 9 (D) are diagrams showing temporal change of singing pitch with respect to reference pitch, and FIG. 9 (A) is a diagram showing vibrato which is singing skill. 9 (B) to 9 (D) show the tremor of the voice due to tension. As shown in FIG. 9 (A), vibrato draws a beautiful waveform whose pitch does not change significantly. The tremor due to tension causes fluctuations in pitch swing as shown in FIG. 9 (B). One way to distinguish between vibrato and tense voice tremor is to consider these differences in characteristics. In order to do so, it is conceivable to compare the slopes of the regression line for the song pitch and the time. In the case of a waveform having no fluctuation in pitch swing as shown in FIG. 9A, the slope of the regression line is close to parallel to the time axis. On the other hand, in the case of the waveform in which the fluctuation of the pitch occurs as shown in FIG. 9B, the slope of the regression line goes away from being parallel to the time axis. In this embodiment, based on the difference between the two characteristics, the slope of the regression line is used to detect tremor due to tension and its degree.

  In order to see the difference in the vibration of the vibrato and the tense voice, as shown in FIG. 9 (C), the number of times of straddling the reference pitch is small as shown in FIG. 9 (D). It is also possible to use the feature of voice tremor due to tension, such as the high amplitude being small.

  FIG. 6 is a flowchart showing a process A for detecting a tension state by singing voice. When the process starts, initialization of the buffer reference position i (S201) and initialization of the number X of voice shake detection detections (S202) are performed. Next, the number of peaks and valleys N (the number of peaks forming the upper peak and the number of peaks and valleys) for the feature amount of the singing voice from the address i to the address i + L stored in the buffer (the basic frequency f0 associated with time in this embodiment) , The sum of the number of valleys forming the lower peak) (S203). If the number of counted mountains and valleys is larger than Nt (S204: Yes), it is determined that the voice is shaking (including shaking due to tension, including both vibrato). Further, the slope α of the regression line from the address i of the buffer to the address i + L is obtained (S205). This is based on the difference between the characteristics of vibrato and tremor due to tension described using FIGS. 9A and 9B, and whether the tremor of the voice detected in S204 is tremor due to tension or not. Is a process performed to determine whether the If the absolute value | α | of the slope of the regression line is larger than the predetermined value αt (S206: Yes), it is determined that the voice is shaking due to tension, and the number X of voice shaking detections is incremented (S207) . On the other hand, if the absolute value | α | of the slope of the regression line is less than or equal to the predetermined value αt (S206: No), it is determined that the voice tremor is a vibrato, and the number X of voice tremor detection is increment do not do. In this way, whether or not the voice is shaking due to tension is determined in the section from the address i to the address i + L of the buffer.

  Then, the current buffer reference position i is incremented (one added) in order to determine the shaking of the voice due to tension in the next section (S208). When i + L is equal to or more than the acquired number n of the fundamental frequency f0 with respect to the incremented buffer reference position i (S209: Yes), the determination is completed for all singing voices. Output (S210), and the process A ends.

  In S114, a value X / n obtained by dividing the number X of vibration detection of voices calculated in processing A by the number N acquired is calculated as the degree of tension. If the calculated degree of tension X / n exceeds the threshold value W (S114: Yes), it is determined that the singing person is tense or more during the singing period by the ratio indicated by the threshold value W. In the present embodiment, the determination of tension is performed at a ratio of the number X of vibrations detected (corresponding to the length of time during tension) of the number of voices acquired (corresponding to the singing period). Not only in such a form, tension may be determined when the number X of vibrations detected for the voice (corresponding to the length of time during tension) has reached a predetermined number or more (a predetermined time or more).

  If it is determined that the user is nervous (S114: Yes), a song evaluation process including correction is performed so that the song evaluation becomes high (S120). In the present embodiment, correction for increasing the song evaluation is performed by executing the process B (S300) for changing the song evaluation criteria and the process C (S400) for adding the score to the calculated song evaluation. There is. On the other hand, if the calculated degree of tension X / n is equal to or less than the threshold W (S114: No), the user determines that the city was not tense, and executes the same song evaluation process (S117) as the standard mode.

  FIG. 7 shows a flowchart of the process B (S300) of this embodiment. The song evaluation process is performed by comparing the reference pitch information and the fundamental frequency f0 which is a feature of the song. If the fundamental frequency f0 within the allowable value P from the reference pitch information, it is determined that singing is correct. In the present embodiment, the standard of judgment is made sweeter by enlarging the normal allowable value P to the corrected allowable value P ′ according to the calculated degree of tension X / n, so that high singing evaluation can be easily made. . Note that, as described in FIG. 10, in the present embodiment, in order to calculate scores for five items, the determination criteria may be corrected for other items other than the pitch.

  The song evaluation process (S115) uses the same algorithm as the song evaluation process (S117) in the standard mode, but differs in that the criterion for determination (for example, the tolerance value P for pitch is changed). That is, the song evaluation information calculated in the song evaluation process (S115) can be referred to as corrected song evaluation information. The calculated song evaluation information is further corrected in process C (S400). In the present embodiment, it is assumed that a score corresponding to the degree of tension X / n is added to the song evaluation information after calculation (the clogs are put on).

  FIG. 8 shows a flowchart of the process C (S400) of this embodiment. The point G to be added is performed by adding the tension degree X / n to the reference point Gt (S401). By adding the point G to the song evaluation information calculated in the song evaluation process (S115), the song evaluation information after correction is calculated (S402). When calculating the score for each item as in the present embodiment, the score may be added to each item. When the song evaluation information (score) to which the score G is added exceeds the highest score (S403: No), a restriction is provided to set the song evaluation information as the highest score (S404).

  Similar to the song evaluation information in the case where it is determined that the user is not in the tension state in the standard mode or the tension consideration mode, the corrected song evaluation information is notified to the user (S116). FIG. 10B is an example of notification of the result of song evaluation when the correction is performed. 10 (A) and FIG. 10 (B) are the results of song evaluation when the same song is performed, and the results of the song evaluation which performed the correction | amendment shown by FIG. 10 (B) are FIG. 10 (B). It can be seen that the song evaluation is higher than when no correction is made. As described above, when the user is nervous, it is possible to suppress the reluctance of the nervous user to sing by notifying the result of the song evaluation shown in FIG. 10A. .

  As mentioned above, although one Embodiment of the song evaluation with respect to the tensioned user was demonstrated about the karaoke apparatus 2, it is possible to employ | adopt various modifications besides the embodiment described.

  In this embodiment, when it is determined that tension is determined, the song evaluation information is corrected at a degree according to the tension degree X / n, but the degree of correction is changed according to the tension degree X / n The correction may be made uniformly at a fixed degree without being performed. Further, the tension consideration mode may be provided in a plurality of stages. For example, it is conceivable to add a degree of correction to the song evaluation to the tension consideration mode. In the tension consideration mode in which the degree of correction is high, it is conceivable to increase the increase in song evaluation, and in the tension consideration mode in which the degree of correction is low, to decrease the increase in song evaluation. When the tension consideration mode is set for each user, setting the degree of correction for each user enables setting according to the user's characteristics, such as setting the degree of correction high for users with a high degree of tension, etc. Become.

  Further, in the present embodiment, the tension state is detected based on the singing voice, but the tension state detection can be performed not only in the form of detection from the singing voice but also in various forms. For example, by capturing an image of the singer with a camera, the tension state may be detected based on tremor of a foot or hand. Alternatively, it is also possible to attach a sensor for detecting physical information such as heart rate, blood pressure, body temperature, tremor, etc. to the user who sings. In recent years, in a wearable terminal such as a watch type, since an environment in which such physical information can be easily detected has been established, it is also possible to use the output of such a wearable terminal.

  In addition, it is preferable that the corrected song evaluation information can not be used for ranking for competing song evaluation in order to secure the fairness of the ranking. Alternatively, when used for ranking, song evaluation information before correction may be used.
