Description

  The present invention relates to a system related to a singer's singing ability screening entry for a predetermined karaoke piece of music, and more particularly to a screening entry system using a karaoke performance terminal and a karaoke host device having a singing ability automatic scoring function.

  In recent years, the level of singing ability of ordinary people has improved due to the spread of karaoke, and there are many events that compete for singing ability, such as amateur karaoke competitions using karaoke accompaniment, and even singing ability that even ordinary people can lose There are many singers. Along with such improvements in singing ability level, there are plans to set and certify grades and ranks in order to meet the demand for objective evaluation of their singing ability. However, in the conventional system that examines and certifies the singing ability, in the singing ability certification in which the judges are witnessed, singers who are not good at singing in public receive strong pressure and sing the examination entry or sing Because power certification is performed at a predetermined place at a predetermined date and time, there is a time constraint, and due to such restrictions, there is a problem that even a singer with excellent singing ability cannot enter a screening. .

  Therefore, recently, a communication karaoke system has been developed in which a singer's singing voice for a predetermined karaoke song is recorded and entry information can be transferred via a network communication line. A singing ability certification system was conceived that allowed entry of entries under equal conditions. For example, in Japanese Patent Application Laid-Open No. 10-26993 (Patent Document 1), the ability level classification means for classifying into a plurality of ability levels according to the score obtained using the karaoke scoring device, and the ability level classification means classify the classification. A karaoke performance terminal having a display means for displaying the name of the ability stage is conceived, and a technique for displaying the singing ability by the name of the ability stage is disclosed. JP-A-2000-231392 (Patent Document 2) describes a communication karaoke system having an audition function in which a karaoke performance terminal digitally records a singer's singing voice and performs data communication with an audition server. The technology is disclosed.

JP-A-10-26993 Japanese Patent Laid-Open No. 2000-231392

  However, in the singing ability certification system using the conventional karaoke performance terminal, the judge is officially inspecting and certifying the singer's singing ability (grade and rank). There is no disclosure of a system that can effectively use the automatic scoring function attached to the performance terminal and that can efficiently perform the final examination even when the number of applicants for examination entry has increased unexpectedly. In other words, the singer did not fully meet the demand for the judges to objectively review their singing ability.

  The present invention has been conceived in order to solve the above problems and inconveniences, that is, a karaoke performance terminal is incidental as a pre-examination for the jury to formally examine and certify the singer's singing ability. The objective is to provide a singing ability screening entry system that can effectively use the automatic scoring function and that can efficiently perform the final screening even when the number of applicants for screening entry increases unexpectedly.

  Therefore, the present inventors have determined that the result of automatic scoring of the singer's singing voice for the predetermined music subject to singing ability certification exceeds the singer's scoring value for the music recorded in the karaoke host device. If there is no entry information of the singer for the song, the entry instruction can be accepted, and if the score value is not exceeded, the entry instruction cannot be accepted, and the above problem can be solved and the singing ability examination is performed. I came up with an entry system.

  That is, the singing ability examination entry system according to claim 1 of the present invention plays a predetermined karaoke piece and records a singer's singing voice with respect to the singing piece. A karaoke performance terminal having a function of automatically singing singing ability, and an entry instruction from the singer, the karaoke performance terminal can receive the ID code of the tune, the recording information of the singing voice for the tune, and the grading result. The singer ID is linked to the entry information and recorded, and the singer's scoring value for the music already recorded in the karaoke host device is recorded. If there is no entry information of the singer for the song Entry instruction can be accepted, if the score value is not exceeded, the entry instruction is not accepted, and if the singer's score value is exceeded, entry information for the song to be managed as information to be judged is newly entered. It is characterized by rewriting.

  Further, in the singing ability examination entry system according to claim 2 of the present invention, the singer ID is confirmed using the singer's ID card, and the karaoke performance terminal has a function of reading / writing the ID card. It is characterized by being attached.

  According to the singing ability examination entry system according to claim 1 of the present invention, even a singer who is not good at singing in public, which is an advantage of a singing ability certification system using a conventional karaoke performance terminal, receives strong pressure. In addition to the effect of not being time-constrained, automatic grading of the singing ability is utilized, and the karaoke host device stores the singer's entry information including the grading information from the karaoke performance terminal and updates it sequentially. For example, when the pre-examination is scored lower than the previous examination entry and no promotion or promotion can be expected in the final examination. This is a case where by rejecting the examination entry, the waste of this examination is eliminated and the number of applicants for the examination entry increases unexpectedly. Efficiently an effect such as may make this assessment.

  Furthermore, according to the singing ability examination entry system according to claim 2 of the present invention, the singer's ID is confirmed using the singer's ID card, and the karaoke performance terminal has an ID card reading / writing function. Since it is attached, it is easy and accurate to confirm the singer's ID in this system, and data related to entry information can also be stored in the ID card. Billing with a card is also possible, and there are effects such as more efficient examination.

  Hereinafter, the optimal example is given about the singing ability examination entry system of this invention, and it explains in full detail.

  FIG. 1 is a block diagram of a karaoke performance terminal in the system of the present invention. In the present invention, a karaoke performance terminal (P) having a function of recording singing voice and automatically scoring singing power is a central control means (CPU: 10) for controlling the operation of the entire apparatus, and various devices connected thereto. The central control means (10) includes a hard disk (11), RAM (12), sound source (synthesizer: 13), mixer (effector: 14), vocal adapter (19), MPEG decoder (20), A synthesis circuit (21), a remote control device (23), and the like are connected. The hard disk (11) stores music data for playing karaoke music, video data for displaying a background video on the display device (22), and the like.

  First, the sound source (13) forms a musical sound signal according to the music data input by the music sequencer (31) executed by the central control means (10). The formed musical tone signal is input to the mixer (14), and this mixer (14) is input via a plurality of musical tone signals generated by the sound source (13), the karaoke microphone (17), and the A / D converter (18). The singer's singing voice signal is mixed with an appropriate balance. The mixed digital audio signal is input to the sound system (SS: 15). This sound system (15) includes a D / A converter and a power amplifier, converts an input digital signal into an analog signal and amplifies it, and emits a musical sound and a singing voice from a speaker (16).

  The singing voice signal converted into a digital signal by the A / D converter (18) is also input to the vocal adapter (19). The vocal adapter (19) collects the singing frequency from the input singing voice signal and also collects the reference frequency input from the music sequencer (31) of the central control means (10). Then, the singing frequency and the reference frequency are synchronized, separated into predetermined time intervals, input to the central control means (10), and the singing ability scoring means (35) performs the scoring process. As a reference, a guide melody included in the music is usually used.

  Singing power automatic scoring is performed by the singing power scoring means (35), and the final score is calculated by a predetermined algorithm that evaluates various singing elements based on the scoring result of the singing frequency. For example, scoring is performed by comparing the singer's singing voice with a reference, and the score is displayed at the end of the song. The hard disk (11) stores a scoring table. The scoring of this scoring table is basically performed for the frequency of the singing (pitch / pitch), the basic score is calculated, the degree of vibrato, the degree of inflection, the sound quality Bonus points are calculated and added (subtracted) to the basic score based on the quality of the game, the quality of the timing, the number of sneezing, and the like. Further, in the RAM (12), in addition to an area for reading various programs and music data, a scoring log area for storing scoring results at the time of scoring is set.

  The background video data (41) stored in the hard disk (11) is encoded in the MPEG2 format, is subjected to playback processing by the background video playback means (34) executed by the central control means (10), and is read out. To the MPEG decoder (20). The MPEG decoder (20) converts the input MPEG data into an NTSC video signal and inputs it to the synthesis circuit (21). The synthesis circuit (21) adds a lyrics telop and a video signal onto the background video signal. An OSD such as a scoring display is synthesized, and the synthesized video signal is displayed on the display device (22).

  The remote control device (23) includes a user interface, a remote control signal transmission circuit (not shown), and the like, and inputs an operation signal according to the user's operation to the central control means (10). The central control means (10) detects the operation signal by the operation input processing means (36) and performs corresponding processing. For example, when a music ID code is input by the remote control device (23), the operation input means (36) detects this and transmits it to the sequencer (30) as a request for karaoke music. In response to this, the sequencer (30) reads the music data identified by the ID code of the music from the music data storage area (40) of the hard disk (11). The sequencer (30) mainly includes a music sequencer (31) and a lyrics sequencer (32). The music sequencer (31) reads track data such as performance data tracks and guide melody tracks in the music data, The karaoke music piece is played by controlling the sound source (13) with this data, while the lyric sequencer (32) is provided with character pattern creating means (33) to read out the data of the lyric track in the music data, Based on this data, an image pattern of lyric telop is created and output to the synthesis circuit (21).

  The recording input interface (24) receives the mixed signal of the musical tone signal received from the mixer (14) corresponding to the music data and the singing voice input to the karaoke microphone, and samples the mixed signal to obtain PCM data. Convert to. This PCM data is singing ability voice data (recording information: 45), along with the ID code (43) of the music and the scoring log (scoring result: 44) automatically scored by the singing ability scoring means (35). It is linked to the ID (42) and stored in the RAM (12). Then, when a predetermined condition described later is satisfied according to the entry instruction of the singer, the song ID code (43), the singing voice recording information (45), and the scoring associated with the singer ID (42) The result (44) is used as entry information, and this information is sent to the karaoke host apparatus via the network communication line, and the karaoke host apparatus manages this as examination target information.

  Here, based on the block diagram of the singing ability scoring function shown in FIG. 2, the automatic scoring in the system of the present invention will be exemplified and described in detail.

  The singing voice signal input from the karaoke microphone (17) is converted into a digital voice signal by the A / D converter (18) and input to the vocal adapter (19). The vocal adapter (19) outputs the digital audio signal as it is to the singing ability scoring means (35), and the singing frequency detector (52) detects the singing frequency (cent value), which is then used as the singing ability scoring means (35). ). The voice waveform of the singing voice signal is sent to the envelope detector (58) to detect the amplitude, and the singing level value is output to the singing power scoring means (35). On the other hand, reference data is input from the music sequencer (31) to the reference frequency detector (51) in synchronization with the performance of the karaoke music. The reference frequency detector (51) extracts pitch information from the note-on event data of the input MIDI data, and outputs the pitch cent value as a reference frequency to the singing ability scoring means (35). Since the vocal adapter (19) receives control information such as note-on information, note-off information, and mark data information from the music sequencer (31), the reference frequency detector (51) also scores the singing ability. Output to the means (35).

  The singing ability scoring means (35) writes the inputted singing frequency and reference frequency in a predetermined memory (not shown) and processes these frequency data with a low-pass filter (LPF: 55, 56). I do. This LPF process obtains flat information by smoothing the pitch change with respect to the reference frequency information or removing techniques such as vibrato with respect to the singing frequency information.

  Scoring in the scoring section (57) is performed based on a predetermined algorithm. Usually, this compares the singing frequency with the reference frequency, calculates the difference (cent value), and based on this difference, each note (note) ) To determine “passed note” and “failed note”, and note-on information and note-off information are input to the scoring unit (57) from the reference frequency detection unit (51). If the singing frequency matches the pitch of the singing melody, it is judged as a passing note, and if the singing frequency matches the pitch of the singing melody is less than the predetermined sample, Judged as a passing note. The basic score is calculated, for example, based on a value obtained by dividing the number of accepted notes by the total number of notes, and the singing ability scoring means (35) includes singing vibrato, inflection, voice quality, timing, squealing, etc. The singing element is detected, and an additional point is calculated based on a predetermined algorithm, and the final score is obtained by adding or subtracting it to the basic score.

  Next, the present invention will be described in more detail based on the display display flowchart of the singing ability examination entry system of the present invention shown in FIG.

Each of D1, D2, D3, D4, D5a, D5b, D6, and D7 shown in FIG. 3 is a display screen of a liquid crystal display (commonly called LCD) attached to a remote control device having a display function. This screen display may be displayed on the display device (22) in FIG. 1 described above together with the LCD of the remote control device.

  When receiving singing ability certification, first, the display screen (D1) for receiving the pre-screening entry is displayed. When the singer selects the “pre-screening entry” icon (61), the singer ID is input. In this case, the singer enters his / her ID by inputting an ID card or a password. Specifically, the “ID card” icon (62) or the “reciting number input” icon (63) is selected, and if the former, the ID is read from the ID card by an accompanying ID card reading / writing device, and the latter If so, the singer inputs the recitation number with the accompanying 10 keys.

  When the singer ID is input, next, in order to specify the singing song to be examined, the display is changed to a display screen (D3) for inputting the ID code of the song, and the singer is an icon of “music code input part”. A message indicating that automatic scoring, recording, and pre-examination will be performed when a predetermined number is entered in (64) using the accompanying 10 keys, and the "confirm" icon (65) is selected to specify a song. The screen changes to the screen (D4), and then a predetermined performance is started.

  When the singer finishes singing, along with the automatic scoring result of the singing ability, a screen is displayed as to whether or not a screening entry can be made. If a screening entry can be made, the display screen (D5a) indicating that indicates “entry”. "" Icon (67) is displayed and the examination entry cannot be made, this icon (67) is not displayed on the display screen (D5b) indicating that. In addition, the singer challenges the pre-screening again by selecting the “trial” icon (68) and listening to the recorded song at that time, or by selecting the “re-challenge” icon (69). can do. This re-challenge system can be used regardless of whether or not the examination entry is possible, but the re-challenge is limited to a predetermined number of times and is not displayed when the predetermined number of times is exceeded.

  When the examination entry can be made as described above, the display screen (D6) changes to the examination fee (entry fee) payment by selecting the “entry” icon (67) on the display screen (D5a). In this display screen (D6), two payment methods are designated, one is a method using a non-contact type IC card capable of sending and receiving money together with personal ID authentication, and the other is a prepaid magnetic method. This is a method of using a card. Specifically, an “ID card” icon (70) or a “prepaid card” icon (71) is selected for payment, and the examination fee is deducted by an accompanying ID card reading / writing device. When a non-contact type IC card is used, the ID card stores data related to entry information together with the billing information. When the payment is completed, the screen changes to a message display screen (D7) indicating that the song has been officially entered along with the name of the singer, the song song name, etc., and then returns to the normal screen (not shown).

  Further, the present invention will be described in detail based on the block diagram around the karaoke host device in the singing ability examination entry system of the present invention shown in FIG. 4 and the schematic diagram of the scoring information ranking table for each singer shown in FIG.

  As described above, the karaoke shown in FIG. 1 is performed by a singer's entry instruction using the remote controller (23) attached to the karaoke performance terminal (P) and the ID card reading / writing device (R / W: 37). Entry information such as the singer ID (42), music ID code (43), scoring result (44), recording information (45), etc. stored in the RAM (12) of the performance terminal (P) is transmitted through the network communication line (N). To the karaoke host device (H). And the communication control means (82) of the karaoke host device (H) stores these entry information in the examination object information management file (84) of the hard disk (HDD: 83), but the singer ID field (85), A music ID code field (86), a scoring result field (87), and a recording information field (88) associated with the singer ID are created and stored, respectively, and managed as examination target information. In addition, the management method of this invention is not limited to this, For example, a personal file may be formed for every singer ID, and music ID code, a scoring result, and recording information may be memorize | stored together in the file.

  And for each singer who entered, a singer's scoring information ranking table (T) based on the sung song and its scoring result is created, and is updated each time the related entry information is uploaded. . FIG. 5 is a schematic diagram of the scoring information ranking table. The ranking table (T) includes a singer ID field (91) and a song ID code field (92) in which the ID code of the sung song is shown. , A scoring result field (93) showing scoring values by automatic scoring, a ranking field (94) in each song based on the scoring values, and finally accreditation as a result of examination by the judges It is mainly composed of a stage (class) field (95).

  In the present invention, when the result of automatic scoring of the singing ability for a predetermined music exceeds the scoring value of the singer for the music already recorded in the karaoke host device at the time of the scoring, or the song for the music When there is no entry information of the person, the entry instruction can be accepted, and when the scoring value is not exceeded, the entry instruction cannot be accepted. That is, except for a new screening entry for a predetermined music piece, if it has already been screened, the screening entry cannot be made unless the scoring value of the target music piece in the scoring result field (93) is exceeded. Furthermore, when the singer's scoring value is exceeded, the entry information for the music managed as examination target information is newly rewritten, and in the scoring information ranking table (T), the target scoring in the scoring result field (93) If the value is rewritten and a promotion / gradation is made after the main examination, the target rank (rank) in the recognized rank (rank) field (95) is also rewritten.

  In this way, in the ranking table (T), since the entry information is sequentially updated each time it is uploaded, the past highest scoring value is always registered. By not accepting examination entries when it is not possible, we can eliminate the waste of the examination and effectively conduct the examination even when the number of applicants for the examination entry has increased unexpectedly. . The scoring information table information for each singer is obtained by downloading the corresponding table from the karaoke host device to the karaoke performance terminal according to the recognition of the singer ID and the instruction of the singer, and using the LCD or display device of the remote control device. By making it display, each singer can also judge the singing ability objectively and relatively about each music.

  Next, the present invention will be described in more detail based on the system flow diagram of the singing ability examination entry system of the present invention shown in FIG.

  First, the singer instructs the pre-examination entry using the remote control device attached to the karaoke performance terminal (S1), and inputs the singer ID by a predetermined method (S2). It is stored in the RAM (S3). Next, when the ID code of the song is designated (S4), the song is played, and automatic scoring and recording of the song voice are performed simultaneously (S5). When the singing is finished, the music ID code associated with the singer ID, the scoring result, and the recording information are temporarily stored in the RAM of the performance apparatus main body (S6). Of these entry information, the scoring result and the music ID code are uploaded to the karaoke host device (S7).

  The uploaded scoring results are compared and evaluated using a scoring information ranking table related to the uploaded scoring results (S8). At this time, it is first determined whether or not there is existing entry information for the target music (S9). ), If not, an entry icon is displayed together with a notice of successful pre-examination (S12). In some cases, the scoring result and the existing scoring value are compared (S10), and if it exceeds this, the entry icon is displayed together with a notice of passing the pre-examination (S12). On the other hand, if it does not exceed this, a notice of pre-examination failure is displayed and the entry icon is not displayed (S11). When the pre-examination is passed and the singer instructs entry (S13), an examination fee is charged (S14). When the singer deposits the examination fee by a predetermined method (S15), the scoring result is registered in the scoring information ranking table of the karaoke host device and the table is updated (S16). The entry information is stored in the hard disk and managed as examination target information (S17).

  As described above in detail, according to the singing ability examination entry system of the present invention, the singing ability automatic grading is utilized, and the karaoke host device stores the singer's entry information including the grading information from the karaoke performance terminal. Since it is judged whether or not a screening entry can be made based on the updated information, for example, in the pre-screening, the scoring is lower than in the previous screening entry, and the final screening and promotion are advanced. If it is not possible, by not accepting the examination entry, it is possible to eliminate the waste of the examination and to perform the examination efficiently even if the number of applicants for the examination entry has increased unexpectedly. There are effects such as.
