Accordingly, the terminal-side control unit 31 functions as a sequencer, and the sound source 34 is controlled based on the read music data. The terminal-side control unit 31 also functions as a lyrics sequencer, reads the data of the lyrics track in the song data, creates an image pattern of the lyrics telop based on this data, and outputs it to the synthesis circuit 40. Further, the terminal-side control unit 31 reads out predetermined background video data in synchronization with the processing of the sequencer and inputs it to the video decoder 39. As a result, karaoke performance in which karaoke music, background video, and lyrics are synchronized is performed.

  When the scoring mode is selected by the remote control device 25 or the operation unit 41, the terminal-side control unit 31 performs scoring mode processing. In the scoring mode process, the singing is scored. In order to perform this scoring, the terminal-side control unit 31 performs low-pass filter processing (LPF processing) on the singing frequency and GM frequency that are periodically transmitted (for example, 30 ms) from the vocal adapter 38. Moreover, the process which detects the envelope (the volume level of a song) of an amplitude from a song audio | voice signal is performed.

  Corresponding to these processes, the scoring log area 32a of the terminal-side RAM 32 includes an area for storing the singing frequency and the GM frequency, an area for storing the LPF frequency, an area for storing the envelope, and a note-on of the song data.

Yes.

  Next, the operation of the karaoke system having the above configuration will be described.

  This karaoke system is characterized by scoring mode processing. The feature will be briefly described. When the scoring mode is selected, the terminal-side control unit 31 (scoring means) evaluates the song by the singer divided into a plurality of evaluation items. In the present embodiment, as described with reference to FIG. 3, the evaluation is made with five evaluation items including pitch, stability, expressive power, rhythm, and vibrato / long tone. The terminal-side control unit 31 transmits the evaluation result (that is, the evaluation value), the user ID of the singer, and the music ID to the host device 1.

  The host-side control unit 11 (maximum evaluation value extracting means) accumulates the user ID, the song ID, and the evaluation result received from the karaoke terminal 21 as evaluation history data, and refers to the user with reference to the evaluation history data 15a. The evaluation history data corresponding to the combination of ID and music ID is specified, the highest evaluation value (highest evaluation value) is extracted for each of a plurality of evaluation items, and the user ID, music ID, and evaluation result are transmitted. Is transmitted to the karaoke terminal 21 that has performed. The terminal-side control unit 31 (scoring means) calculates the score based on the highest evaluation value received from the host device 1 as the maximum potential score for the karaoke piece and uses the latest singing from the evaluation value corresponding to the most recent singing. Score is calculated. Further, the ratio of the most recent singing score to the maximum potential ability score is calculated as the singing ability ratio.

  And the terminal side control part 31 (notification means) outputs each information, such as the highest evaluation value, the maximum potential score, the latest singing score, and a singing ability ratio, to the synthetic | combination circuit 40 (notification means). The synthesis circuit 40 synthesizes this information with the video signal of the background video, and outputs the synthesized video signal to the monitor 23 (notification means). The monitor 23 displays a video of the highest evaluation value, the maximum potential score, the latest singing score, and the singing ability ratio for each of the plurality of evaluation items on the scoring result display screen.

  By visually recognizing this video, the singer can obtain the maximum value of the singing ability that he has as an objective index, and his objective score for the most recently sung karaoke piece as an objective index. You can know based on. Further, the singer can know his / her proficiency level for the most recently sung karaoke piece based on an objective index.

  Hereinafter, the operation of the scoring mode process described above will be described in detail based on the flowchart of FIG. This flowchart shows processing performed by the host-side control unit 11 and the terminal-side control unit 31 in accordance with the execution of the scoring program.

  In the scoring mode process, in step S1, the terminal-side control unit 31 determines input of sample data. Here, the sample data is various data updated every predetermined period, and corresponds to an envelope (singing volume level), a singing frequency, and a GM frequency. And if an envelope, a singing frequency, and GM frequency are input, it will transfer to step S2.

  In step S 2, the envelope is written in the scoring log area 32 a of the terminal side RAM 32. And it transfers to step S3 and the raw singing frequency and GM frequency which are not made LPF processing (low-pass filter processing) are written in the scoring log area | region 32a. Next, in step S4, the terminal side control unit 31 performs LPF processing. That is, the LPF process is performed on the raw singing frequency and the GM frequency. The singing frequency and GM frequency that have been subjected to the LPF process are written in the scoring log area 32a as the LPF frequency in step S5.

  If the terminal side control part 31 receives the note-on event data from the vocal adapter 38 in step S6, it will transfer to step S7. In step S <b> 7, note-on information is written in the terminal side RAM 32. The timing at which the note-on information is written is recognized as the sounding timing in the guide melody. Moreover, if the terminal side control part 31 receives the note-off event data from the vocal adapter 38 in step S8, it will transfer to step S9. In step S <b> 9, note-off information is written into the terminal side RAM 32.

  Next, the process proceeds to step S10, and the pass / fail of the scoring note is determined. This determination is performed by the terminal-side control unit 31 based on the singing frequency and the GM frequency that have been subjected to the LPF process. Briefly, it is determined as a passing note when the difference between these frequencies is within the criterion value, and is determined as a failing note when it exceeds the criterion value.

  If it is determined whether or not the scoring target note is acceptable, the process proceeds to step S11, where vibrato and long tone are determined. Vibrato is determined by the terminal-side control unit 31. For example, periodicity is detected for a group of singing frequencies not subjected to LPF processing, and it is determined that there is vibrato when there is periodicity. The determination of the long tone is made based on the stability of the singing pitch.

  Next, the process proceeds to step S12, and the timing is determined. The terminal side control part 31 detects the time difference of the change of a singing frequency and the change of GM frequency by timing determination. In step S13, the presence / absence of sneezing or the like is determined. Scribbling is determined by whether or not the singing frequency has changed in a waveform that satisfies a predetermined condition. The presence or absence of a fist and the presence or absence of a fall are also determined based on the singing frequency.

  If it is determined whether or not there is scouring or the like, the process proceeds to step S14. In step S14, the terminal-side control unit 31 writes the above-described determination result in the scoring log area 32a. That is, the determination result of pass / fail of the scoring target note, the determination result of vibrato or long tone, the timing point, and the determination result such as squeak and fist are written. And it transfers to step S1 and the above-mentioned process is repeatedly performed until karaoke music is complete | finished (S15).

  If it is determined in step S15 that the karaoke song has been completed, the process proceeds to step S16 and an evaluation process is performed. In this evaluation process, the latest singing evaluation based on the determination results obtained in the processes of steps S1 to S15 described above and the past karaoke pieces to be scored by the singing target singer transmitted from the host-side control unit 11 are recorded. Using the highest evaluation, the evaluation result is displayed on the monitor 23.

  FIG. 7 is a flowchart for explaining the evaluation process. Hereinafter, the evaluation process will be specifically described with reference to this flowchart.

  In this evaluation process, first, the latest evaluation value is acquired in step S21. Here, the terminal-side control unit 31 refers to the determination result written in the scoring log area 32a, and acquires the evaluation value for the karaoke piece immediately after singing. Specifically, evaluation values are acquired for each evaluation item of pitch, stability, expressive power, rhythm, and vibrato / long tone.

  The pitch is evaluated on the basis of the number and time of accepted notes. That is, a higher evaluation value is assigned as the number of accepted notes increases or as the accumulated time of accepted notes increases. The stability is evaluated based on, for example, the deviation of the singing frequency with respect to the GM frequency. A smaller evaluation value is given as the deviation is smaller.

  The evaluation of expressive power is made based on intonation, fisting, fist and fall. And the presence or absence of intonation is determined based on the sound volume. For example, the determination is made based on the deviation between the average volume of the phrase and the average volume of each note. Based on the point calculation table, the higher the number of inflections, the higher the evaluation value is given. The determination result written in step S <b> 14 is used for the number of falsifications, the number of fistings, and the number of falls. Based on the point calculation table, a higher evaluation value is given as the number of times increases.

  The rhythm is evaluated based on the result of the timing determination in step S12. A higher evaluation value is given as the change timing based on the singing frequency is closer to the change timing based on the GM frequency. For the vibrato and the long tone, the evaluation value based on the point calculation table is given with reference to the determination result written in step S14.

  If the latest evaluation value is acquired, it will transfer to step S22 and the calculation of the latest singing score will be performed. Here, the terminal-side control unit 31 calculates a score corresponding to the latest evaluation value calculated in step S21, that is, a score for a karaoke piece immediately after singing.

  Next, the process proceeds to step S23, and the latest evaluation value is transmitted and received. Here, the latest evaluation value, the latest singing score, the user ID of the singer, and the music ID calculated by the terminal-side control unit 31 are transmitted to the host device 1. The host-side control unit 11 stores the latest evaluation value, the latest singing score, the user ID, and the song ID received from the karaoke terminal 21 in the history information storage area of the host-side HDD 13 and updates the history data 15a.

  Next, the process proceeds to step S24, and the highest evaluation value is extracted. Here, the host-side control unit 11 refers to the history data 15a stored in the customer information storage area 15, identifies the history data corresponding to the combination of the user ID and the music ID received from the karaoke terminal 21, and The highest evaluation value for each evaluation item is extracted from the inside. In the example of FIG. 3, regarding the singer whose user ID is ABC0123, the history of evaluation results of the karaoke music corresponding to the music IDX-XXX-XX is specified, and five evaluations from the pitch to the vibrato / long tone are specified. The highest evaluation values X1 to X5 are extracted individually for the items.

  If the highest evaluation value is extracted, the process proceeds to step S25, where the highest evaluation value is transmitted / received. Here, the highest evaluation value extracted by the host-side control unit 11 is transmitted to the karaoke terminal 21 that has transmitted the latest singing score, user ID, and music ID. The terminal-side control unit 31 stores the highest evaluation value received from the host device 1 in the scoring log area 32a of the terminal-side RAM 32.

  Next, the process proceeds to step S26, and the potential score is calculated. Here, the terminal-side control unit 31 refers to each maximum evaluation value stored in the scoring log area 32a, and calculates a score corresponding to each maximum evaluation value, that is, the maximum potential score for the karaoke piece to be scored. .

  Next, it transfers to step S27 and calculation of singing ability ratio is performed. Here, the terminal-side control unit 31 calculates the ratio of the latest singing score to the maximum potential score (the latest singing score / the maximum potential score) as the singing capability ratio.

  If a singing ability ratio is calculated, it will transfer to step S28 and a result will be alert | reported. Here, the terminal side control part 31 outputs the information of scoring results, such as the latest evaluation value, the latest singing score, the highest evaluation value, the maximum potential ability score, and the singing ability ratio, to the synthesis circuit 40. The synthesis circuit 40 synthesizes each information with the video signal of the background video, and outputs the synthesized video signal to the monitor 23. The monitor 23 displays a predetermined video on the scoring result display screen.

  FIG. 8 is an example of a result notification image displayed on the monitor 23. As shown in this figure, the most recent singing score display area 23a of the monitor 23 displays the most recent singing score, and the maximum potential ability score display area 23b displays the maximum potential ability score.

  In this way, since the new index of maximum potential score is displayed on the monitor 23, the singer to be scored obtains an objective evaluation of the karaoke piece to be scored based on the maximum potential score. Can do. And since the latest singing score and the maximum potential ability score are displayed on the monitor 23, the singer can sing with the power of the potential ability of the singer himself the singing result this time. Can be recognized as an objective index.

  In this embodiment, since the latest potential score is displayed in the fractional numerator and the maximum potential score is displayed in the denominator, the singer can also intuitively recognize the current singing result. In addition, since the potential ratio is displayed as a numerical value in the potential ratio display area 23c of the monitor 23, the singer can determine his / her proficiency level for the most recently sung karaoke piece based on an objective index. Can know.

  In the evaluation value display area 23d of the monitor 23, the latest evaluation value and the highest evaluation value are drawn on a radar chart for each evaluation item. In this embodiment, the latest evaluation value is drawn with a solid line, and the highest evaluation value is drawn with a dotted line. Thus, since the latest evaluation value and the highest evaluation value are drawn on the same chart, the singer can easily compare the evaluation value in the latest singing with the highest evaluation value.

  The above description of the embodiment is for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof. For example, you may comprise as follows.

  In the above-described embodiment, pitch, stability, expressive power, rhythm, and vibrato / long tone are exemplified as evaluation items, but the evaluation items are not limited to these. For example, each item (e.g., intonation and sneezing count) for evaluating expressive power may be used as the evaluation item.

  In the above-described embodiment, the information of the highest evaluation value is transmitted to the terminal-side control unit 31 in the evaluation process (S16). However, the present invention is not limited to this configuration. For example, information on the highest evaluation value may be transmitted to the terminal-side control unit 31 before scoring the most recent song. In this case, the terminal side control part 31 should just update the highest evaluation value in consideration of the evaluation result of the latest singing, and may use the updated highest evaluation value. The evaluation result of the latest singing is at an appropriate timing. What is necessary is just to transmit to the host side control part 11.

  In the above-described embodiment, the case where the latest evaluation value and the highest evaluation value are displayed on the radar chart in the evaluation value display area 23d is exemplified, but the display mode is not limited to the radar chart. For example, it may be displayed in the form of a line graph or in the form of a bar graph.
