This is because the singing score value of a singing singer is generally lower than the singing score value of a high score singer. Therefore, the function of the singing singing singing judgment means 50 compares the singing technique characteristic of the user having a low singing score value (the user who may be a singing singing singer) with the original singing technique characteristic, and approximates the singing technique characteristic. If the singing technique feature approximate value of the user with a low singing score value is greater than or equal to a predetermined value, the singing battle (song mimicry challenge) between the high score singer and the singing singer judge. The calculation method of the singing technique feature approximation value may be obtained by comparing the singing technique feature of each user with the original singing technique feature and quantifying the degree of approximation in accordance with the calculation method of the singing scoring value.

  In addition, you may determine with a singing singing singer when performing singing singing a predetermined number of times (for example, 5 times) or more. Thereby, the general singer who performed the same singing as the singing singing by chance and the singing singing singer who performed the singing singing based on his / her will can be distinguished.

(S1) When it is a singing battle, it is determined whether any one of the singing score values of each user linked to the music ID is equal to or greater than a predetermined value (for example, 80 points) (S2). Furthermore, it is determined whether or not the difference between the singing score values (single grading average values) of each user is equal to or greater than a predetermined value (for example, 15 points) (S3).

  And any one of each user's singing scoring value is more than predetermined value (national average value etc.), and the difference of the singing scoring value (singing scoring average value etc.) of the user who performs a singing battle is a predetermined value. When it is determined as above, the singing technique characteristics stored as the singing score history of the user having a low singing score value and the original singing technique characteristic storing means 63 by music are stored for the singing competition music. The singing technique feature approximate value is calculated by comparing with the original singing technique feature (S4). Subsequently, it is determined whether or not the singing technique feature approximate value of the user having a low singing score is a predetermined value (for example, 60 points) or more (S5), and the singing technique feature approximation of the user having a low singing score value is determined. If the value is greater than or equal to the predetermined value, it is determined that the song is a singing challenge (S6).

  Subsequently, when it is determined that the song is a singing challenge, the specified singing singers are displayed (S7), and the listener is made aware of who the singing singers are (see FIG. 5). ). The step (S7) can be omitted. Subsequently, in singing scoring for singing imitation challenge, the singing scoring is performed by expanding the pitch width that is the pitch scoring reference value (for example, standard pitch width ± 50 cents) for the singing scoring reference data (S8). .
