  FIG. 1 is a diagram showing a configuration of a karaoke system according to an embodiment of the present invention. The karaoke system in the present embodiment is composed of a karaoke device 2 (also called “commander”) and a remote control device 1, which are connected to each other by a LAN 100 wirelessly and by wire.

  The karaoke device 2 installed in the store can accept various instructions from the user by the remote control device 1 (for example, 1a, 1b). In addition, the remote control device 1 includes a touch panel display screen in which the display unit 11 and the operation unit 17 are shared, and is capable of providing various information to the user and inputting operations. The remote control device 1 is wirelessly connected to the karaoke device 2 via an access point 110 installed on the LAN 100. For example, remote control devices 1a and 1b are associated with the karaoke device 2, and information can be transmitted and received via the LAN 100a. In addition, the remote control devices 1a and 1b and the karaoke device 2 can perform short-range communication using the infrared communication unit 16 or the like.

  Further, in the karaoke system of the present embodiment, a karaoke host 5 (server device) is provided via the Internet to provide various services to the user, and music information, user information, post information (karaoke post video / audio, assistance) Information necessary for various services such as information) is stored. Then, through the router 120, the above-described information can be transmitted / received to / from the karaoke device 2 or the remote control devices 1a and 1b.

The karaoke apparatus 2 functions mainly with the control unit 30 that performs overall control, and can perform performance processing, music reservation processing, scoring processing, and the like as main functions. In the performance process, the performance information corresponding to the song for singing designated by the user is inputted into M by the input unit 21 or the remote control device 1.
This is a process of causing the sound control unit 70 including the IDI sound source to perform and emitting sound from the speaker 42. At this time, sound input from the singing microphones 44a and 44b is also emitted from the speaker 42 together.

  The music reservation process is a process for selecting and reserving a song for singing based on a designation from the user. In this embodiment, it is executed in cooperation with the remote control device 1. A user command input from the operation unit 17 of the remote control device 1 is transmitted to the karaoke device 2 via the infrared communication units 19 and 23 or the LAN 100. The processing result in the karaoke device 2 is displayed on the display unit 11 on the remote control device 1 side, and the user can visually recognize various information for music selection. The karaoke device 2 and the remote control device 1 can execute various processes such as a log-in process for providing individual user services as well as the music designation process.

  The scoring process is a process performed in conjunction with the performance process, and is a process of converting and evaluating the singing ability of the user who sings. This scoring process is executed by comparing the singing pitch information corresponding to the performance information and the input voice information input from the singing microphone 44. This comparison is mainly performed by comparing the pitches, and the higher the degree of coincidence between the singing pitch information and the input voice information, the higher the score. In addition to such pitch comparison, when singing techniques such as squeak, vibrato, and fist are determined in the input voice information, it can be added to the score as a skill score.

  FIG. 2 is a diagram showing a top screen according to the embodiment of the present invention, that is, a screen immediately after starting the remote control device 1. In the present embodiment, various information is provided to the user who operates the remote control device 1 by displaying on the display unit 11 of the remote control device 1. As the operation unit 17 of the remote control device 1, a touch panel that directly operates buttons, icons, and the like displayed on the display unit 11 in addition to various mechanical switches such as cursor keys can be employed. .

  In the karaoke system of the present embodiment, a plurality of users can input necessary information (user identification information and password described later) from the touch panel display screen of each remote control device 1 and log in. Information related to user login is always displayed at the top of the screen. A login user field 103 is provided for displaying a logged image (avatar) of the logged-in user. In addition to the image imitating a person or a character, various forms such as figures and symbols can be adopted as the portrait image.

  In addition, a guest icon 102 for a user who does not have an account and a user changeover switch 101 for switching the user are displayed. The logged-in user can receive various services using his / her user information by selecting a portrait image displayed in the logged-in user column 103 or operating the user changeover switch 101. Further, a user who does not have an account can receive a general service such as music selection by operating the guest icon 102. Note that when switching users, authentication such as a password may be performed, but switching may be performed simply without performing authentication.

FIG. 3 is a diagram for explaining user information stored in the host 5 for each user. In the present embodiment, the user information includes various information related to the user such as personal information, a my song table, and a my artist table. The user information is stored in advance in the storage unit 51 of the karaoke host 5. The user information is associated with user identification information and a password for the user to log in to the karaoke host 5 from the remote controller 1 and use the information. The personal information includes a user name (not limited to an actual name but may be a nickname), gender, age, song age, place of residence, hobby, and the like. These various types of information can also be set by logging in with the remote controller 1 or a personal computer (not shown) connected to a network such as the Internet, a portable information terminal, or the like.

  Note that the song age is an age different from the actual age calculated based on the music selected by the user. The average age of the user who sang each song is averaged to calculate the song age for each song. The song age of each user is calculated by averaging the song ages of songs selected by the user.

  The My Uta table is a table that stores music registered by the user, and includes music identification information, pitch adjustment values, past singing grading information (highest or past multiple times), and the like. ing. Based on this My Uta table, the user can call, reserve, and play a favorite song registered in the past. At that time, by using the registered pitch adjustment value, it is also possible to perform (reproduce) with a pitch suitable for one's own song.

  The my artist table is a table for storing artists (singer) registered by the user, and includes singer identification information. Based on this My Artist table, the user can call, reserve, and perform a favorite favorite artist's song (a song or a related song).

  The history table is information that records various types of information related to the music that the user has played in the past. In the present embodiment, the music identification information of the music, the performance of the music that has been played in the past (the user has reserved and played) Singing date and time indicating the date and time, singing scoring information, and the like. Based on this history table, the user can call and sing songs that have been played in the past. Note that the history table of the present embodiment includes recommended pitch values in addition to the various types of information described above. This recommended pitch value is a pitch value that is expected to obtain a high score in the scoring process, and its calculation and the like will be described in detail in the explanation in a later process.

  FIG. 4 is a diagram showing how user information is transmitted and received. A user who visits the karaoke store inputs his / her own user identification information and identification information including a password, or reads the identification information stored in the IC card with an IC card reader provided in the remote control device 1 or the like. Thus, the authentication process S101 is executed. The karaoke device 2 or the remote control device 1 that has read the user identification information transmits the identification information to the karaoke host 5 (S102), and the karaoke host 5 that has received the identification information is based on the database stored in the storage unit 51. The user information of the corresponding user is extracted (S121) and transmitted to the karaoke device 2 or the remote control device 1 that has made the inquiry (S122).

  On the karaoke device 2 side that has received the user information (S103), various service processes such as a music selection process and a performance process are provided based on the received user information (S104). When logout is requested by the user (S105), service processing is interrupted, and various histories (logs) during service processing or user information reflecting setting changes by the user are transmitted to the karaoke host 5 (S106). Here, user information may transmit only the updated difference other than transmitting all information. The karaoke host 5 updates the database stored in the storage unit 1 based on the received user information (S124).

The flow from one user authentication process (login process) to logout has been described above. However, in the karaoke apparatus 2 and the remote control apparatus 1 of the present embodiment, a plurality of authenticated users (authenticated users) log in simultaneously. The user providing the service (hereinafter referred to as “active user”) can be switched and used by using the user interface described in FIG. Yes.

  FIG. 5 is a diagram showing an active user top screen according to the embodiment of the present invention. As shown in this figure, when a plurality of users are logged in, the logged-in user column 103 displays the logged-in images 103a to 103e (face portions in this embodiment) of the logged-in user. In the logged-in user column 103, the user whose background is highlighted at the right end is the active user 103e. In the state shown in the figure, the service for the active user 103e, that is, the user information of the active user 103e is used. The service is running. On this active user top screen, by selecting “Search for a song”, a search based on a singer name and a song name can be performed as in a conventional song book.

  When a song is selected as an active user, the song confirmation screen shown in FIG. 6 displays the song name, singer name, singing, etc. to make the user confirm that there is no mistake in the song to be reserved. At this time, if the pitch (key) that can be sung for the selected music is known in advance, it is possible to set the pitch adjustment value when performing by changing the “pitch setting”. ing. By operating the “change” button at the lower right of the key setting, a pitch setting screen is displayed, and the pitch adjustment value can be set.

  When the “reservation” button is operated on the music confirmation screen, reservation information including user identification information, music identification information, a pitch adjustment value, and the like is transmitted from the remote control device 1 to the karaoke device 2. The received karaoke apparatus 2 sequentially adds reservation information to the reservation table and executes performance processing.

  FIG. 7 is a flowchart showing main processing executed by the karaoke apparatus 2 according to the embodiment of the present invention. When the performance process is started after the karaoke apparatus 2 is turned on, the reservation table is checked (S201), and the presence or absence of the music to be performed next is determined (S202). If it is determined in the reservation table that there is a song to be played next (S202: Yes), a performance process (S300) is executed. The performance process of the present embodiment is configured to execute a scoring process and a pitch recommendation process simultaneously with the performance. In the scoring process, the singing scoring information is calculated by comparing the pitch of the input voice information input from the singing microphone 44 with the singing pitch information corresponding to the performance information. On the other hand, in the pitch recommendation process, the pitch corresponding to the best singing scoring information is determined as the recommended pitch by comparing the pitch of the input voice information with the singing pitch information for each pitch using the same algorithm as the scoring process. It is processing to do.

  FIG. 8 is a flowchart showing performance processing according to the embodiment of the present invention. When the performance process is started, first, singing scoring information calculated at the previous performance is initialized (S301). In the present embodiment, when input voice information is input from the singing microphone 44 (the magnitude of the input voice information is equal to or greater than a threshold value), the input voice information and the singing pitch information are compared. When it is determined that there is input voice information (S302: Yes), n = 0 is set. This n is an index indicating a pitch. In this embodiment, 11 singing pitch information from n = 1 (pitch: -5) to n = 10 (N) (pitch: +5) is the same as the input pitch information. Contrast is done.

  As described above, in this embodiment, all the pitches that can be set in the karaoke apparatus 2 are compared with the input voice information. However, the pitches to be compared are within a predetermined pitch from the pitch that is actually played. It may be limited (for example, ± 1, ± 2, etc.). Usually, it is rare that the recommended pitch is extremely far from the pitch of singing. Therefore, it is possible to determine the recommended pitch by limiting the pitches to be compared in this way. Moreover, in such a form, the number of singing pitch information to be compared can be reduced, and the load on the control means can be reduced.

  In S305, singing pitch information corresponding to the set nth pitch is acquired. Singing pitch information can be acquired as main melody information included in performance information or information associated with identification information of performance information. This singing pitch information is acquired for each pitch, but it is possible to store the singing pitch information for each pitch, and it is used by shifting in accordance with the pitch using the standard singing pitch information. It is good to do.

  In S306, a score is calculated based on the pitch of the input voice information input from the singing microphone 44 and the amount of deviation between the singing pitch information acquired in S305. In S307, the score calculated in S306 is added to the singing score information of the nth pitch (may be subtracted), and the singing score information of the nth pitch is updated. As described above, in S305 to S307, the singing score information of the nth pitch in a predetermined period during the music performance is calculated. In S308, after incrementing n by one, S305 to S307 are repeatedly executed until it is determined that n = N (S304: Yes), so that n = 0 to N (N = 10 in the present embodiment). Comparison between the singing score information of different pitches and the input voice information is executed.

  FIG. 9 schematically shows how the input voice information and the singing pitch information are compared. Here, the performance pitch information when the performance pitch is “−2” and the performance pitch information that is +1 and −1 pitches with respect to the performance pitch are indicated by a bold line (pitch: −1) and a broken line (pitch: − 2), indicated by a one-dot chain line (pitch: -3). Moreover, the time transition of the input voice information is shown by a thin line. In the normal scoring process, the singing scoring information is calculated by comparing the performance pitch information corresponding to the pitch to be played and the pitch of the input voice information, but in this embodiment, in addition to this comparison, The singing scoring information is calculated for each pitch by comparing the input voice information and the performance pitch information of other pitches.

  Even when singing at the pitch of performance information that is actually played, there may be a pitch that is more suitable than singing at a pitch other than the pitch from the viewpoint of scoring. This is due to the singing characteristics of the singer or the voice quality of the singer, and may differ from the pitch that the singer can easily sing. In this embodiment, in view of such a situation, the user may be notified of a pitch that may be used to calculate good singing scoring information in the scoring process as a recommended pitch (high score recommended pitch), and used in later singing. The purpose is to make it possible. Also in the schematic comparison of FIG. 9, the degree of coincidence between the input voice information and the performance pitch information is substantially higher at a pitch (pitch: −1) that is one higher than the performance pitch (pitch: −2). I can read. In such a case, the user is notified of the pitch “−1” as the recommended pitch.

  Returning to the flowchart of FIG. By repeatedly executing S302 to S308 until it is determined that the performance has ended (S309: No), singing scoring information is calculated for each interval for each of a plurality of sections. When the performance is completed, the singing score information for each pitch (n = 0 to N) is gathered, and the pitch with the highest singing score information is determined as the recommended pitch (high score recommended pitch) (S311). ).

  When the performance process (S300) described in FIG. 8 ends during the main process in FIG. 7, the recommended pitch determined in the performance process is notified to the user (S203). FIG. 10 shows a recommended pitch notification screen according to the embodiment of the present invention. In the present embodiment, the recommended pitch notification screen shown in FIG. 10 is displayed on the monitor 41 connected to the karaoke device 2, but the notification of the recommended pitch is not limited to such a form. It is good also as displaying on the display part 11 or employ | adopting the alerting | reporting by an audio | voice.

The recommended pitch notification screen of FIG. 10 displays the avatar of the singer, the user name (Mr. A), the name of the song sung (winter flower), and the artist name (Akasana). Also, the singing scoring information (singing score) at the actually played performance pitch (performance pitch: -2) and the recommended pitch (-1) which is the pitch that has acquired the best singing scoring information among a plurality of pitches. Is also displayed. The user (singer) can confirm the recommended pitch (-1) that can obtain good singing score information on the recommended pitch notification screen. In the present embodiment, the singing scoring information (singing score) is also displayed for the performance pitch actually played and the recommended pitch. Based on such notification, when the user changes the pitch to the recommended pitch, the user can check how much score can be expected.

  Furthermore, in the present embodiment, the recommended pitch can be registered in the My Uta table in the user information. Returning to the flowchart of FIG. 7, in S204, first, it is confirmed whether or not the music played in the performance process is registered in the My Uta table. If the music is not registered in the My Uta table, a registration user interface that asks the user to register the music and the recommended pitch value is displayed to ask the user whether registration is possible. In the lower part of the screen of FIG. 10, the registration user interface is displayed. The user uses the operation unit 21 of the karaoke device 2 or the operation unit 17 of the remote control device 1 to select “Yes” or “No” to determine whether registration is possible. When registration is selected (S206: Yes), the music identification information of the music is recorded in the My Uta table, and the recommended pitch value is recorded as the pitch adjustment value (recording process). By registering in the My Uta table, the next time the same music is selected, the recommended pitch is set, and the user is expected to obtain a high score in the scoring process.

  On the other hand, when the sung song has already been registered in the My Uta table (S204: Yes), first, the determined recommended pitch value is registered in the My Uta-table and the pitch adjustment value is different. It is determined whether or not. If they are different, the registration user interface is displayed (S206), as in the case where they are not registered in the My Uta table, and the user is asked whether registration is possible. On the other hand, when the recommended pitch value and the pitch adjustment value registered in the My Uta table are the same, the registration user interface is not displayed because there is no need to change the pitch adjustment value already registered. In this case, a message indicating that the registered pitch adjustment value and the recommended pitch value are the same may be notified (displayed).

  As described above, the series of processes from the start of the performance of the music to the notification of the recommended pitch has been described. However, according to the karaoke device of the present embodiment or the karaoke program executable by the karaoke device, the music is played. The user's input voice information is compared with the singing pitch information for each pitch using the same algorithm as the scoring process, the singing scoring information for each pitch is calculated, and the pitch corresponding to the best singing scoring information is calculated. The recommended pitch is determined. By notifying the user of such a recommended pitch, the user can confirm a pitch at which good singing scoring information can be acquired in the scoring process.

  In the embodiment described above, the notification of the recommended pitch is performed immediately after the performance, but this notification may be performed when the same music is selected next time. As described in FIG. 3, the recommended pitch value is recorded in the history table in association with the music identification information of the sung music (recording process). When the same music is selected again using this history table, the recommended pitch is notified. FIG. 11 shows a pitch setting screen according to the embodiment of the present invention. This pitch setting screen is a window displayed on the music confirmation screen when the pitch setting change is executed on the music confirmation screen (FIG. 6) displayed when the music is selected. It is possible to set the pitch at the time of performance.

FIG. 11 shows a case where the pitch setting screen is opened on the music confirmation screen shown in FIG. 6, and the pitch “−2” is set in advance immediately after the display. On this pitch setting screen, the user can set the pitch that he wants to change. For reference information, “standard”, “original song”
"High score recommended pitch" is displayed along with the corresponding pitch. “Standard” is a pitch (± 0) set to facilitate singing for karaoke, and is set to this pitch when initially selected. The “original song” is the original pitch that the artist actually sings (“+3” in the figure), and when the user wants to sing at the original pitch, the user sets the pitch to this “original song”. The “high score recommended pitch” is a pitch (“−1” in the figure) corresponding to the recommended pitch value determined in the performance process of FIG. The user who wants to obtain good singing score information in the scoring process can try to improve the scoring result by setting to this “high score recommended pitch”.

  In this way, by using the history table in the user information, it is possible to notify the user of the recommended pitch when the music is selected next time. This notification form may be performed in combination with the notification of the recommended pitch immediately after the performance described in FIG.

  Now, another embodiment of the present invention will be described. Although the performance processing for determining the recommended pitch through one piece of music has been described with reference to FIG. 8, the recommended pitch may be determined for each section of one piece of music and notified to the user. FIG. 12 is a flowchart showing a performance process according to another embodiment. In the present embodiment, the recommended pitch for each predetermined section of the music (section recommended pitch) and the recommended pitch through one music are determined. Here, the same reference numerals (S301 to S308) are given to the processes common to the performance process of FIG. Here, processing common to FIG. 8 is omitted, and only different processing is described.

  As in FIG. 8, the singing score information for each pitch is calculated by repeatedly executing S302 to S308. In this embodiment, the singing score information for each pitch is calculated for each predetermined section. This is different from the above-described embodiment. In addition, the section of the music used in the present embodiment is a section in the music called commonly known as A melody (No. 1) and B melody (No. 2). FIG. 13 schematically shows the section employment form of the present embodiment. The A melody section is a singing section sandwiched between the prelude and the interlude, and the B melody section is a singing section sandwiched between the interlude and the follower. In addition to such a form, it is possible to appropriately adopt a section such as a rust (swell) portion of the music. The section can be determined by attaching a section determination flag or the like to the performance information.

  If the end of one section is determined during the calculation of the singing score information for a certain section (S320: Yes), the pitch with the highest singing score information in the section is determined as the section recommended pitch (S322). Thereafter, when the performance is continued (S323: Yes), the singing scoring information is calculated for the other subsequent sections, and the section recommended pitch is determined for each section (S322). When it is determined that the performance has ended (S323: No), the recommended pitch for the entire music is determined from the recommended pitches for each section (S324). The recommended pitch to be determined here is the section recommended pitch for each section. Yes. In addition, the case where the time length etc. for every area differ according to the employ | adopted form of an area is considered. In such a case, it is preferable to correct the singing grading information according to the characteristics of the section.

  As described above, in the embodiment using the performance process of FIG. 12, it is possible to determine the recommended pitch for each section in the music. The recommended pitch determined in this way is notified to the user at the end of the performance or when selecting the next song. The user can confirm the recommended pitch and use it when playing the music.

In the two embodiments described above, the recommended pitch and the recommended section interval are determined by calculating the singing score information during the performance processing period. However, the calculation of the singing score information is limited to the performance processing period. It may be performed after the performance is finished. In this case, it can be executed by recording (recording) the input voice information or by recording a pitch extracted from the input voice information. In such a case, it is not necessary to perform comparison with a plurality of different singing pitch information in real time, and it is possible to perform in a time shorter than real time by the processing capability of the control means.

  Specifically, in the performance process of S300, the recording of the input voice that is the singing voice is executed together with the start of the performance information corresponding to the reserved music. At this time, the input audio information to be recorded is associated with the progress of the musical performance and is recorded on the hard disk 32 as a recording means. For example, the time information of the performance information may be recorded in association with the progress of the performance of the input audio information. After completion of the performance processing S300, the input voice information recorded on the hard disk is read out and reproduced while synchronizing the input voice information and the performance information based on the time information described above, and the input voice information and singing pitch information for each of a plurality of intervals. Contrast with. In such a form, since input voice information is recorded, it is possible to repeatedly reproduce the input voice information. Therefore, it is also possible to reproduce the input voice information for each singing pitch information of each pitch to be compared, compare with the singing pitch information of one pitch in one playback, and play back each pitch. is there.

  FIG. 14 shows a flowchart of performance processing according to another embodiment. In the present embodiment, similar to the performance process of FIG. 12, the process is the same in that the section recommended pitch is determined for each section in the music. Therefore, the processes (S301 to S324) having the same reference numerals as those in FIG. 12 are covered by the description in the above-described embodiment. The difference from the above-described embodiment is that, every time a section changes, a process (S325) for changing the performance pitch to be performed by the performance means (sound control unit 70) to the recommended section pitch determined in the previous section is added. It is a point.

  By switching to the section recommended pitch determined in the previous section and performing, the user (singer) can check whether it is actually possible to obtain good singing score information or whether it is a pitch that is easy to sing. Is possible. In the section setting of FIG. 13, after the section recommended pitch is determined by the A melody, the performance is performed by switching to the section recommended pitch by the B melody. In this case, it is preferable to notify the user that the pitch is switched by using the monitor 41 or the speaker 42 during the interlude.

  Note that the present invention is not limited to these embodiments, and embodiments configured by appropriately combining the configurations of the respective embodiments also fall within the scope of the present invention.
