To do. Moreover, when login processing is performed based on the login presenting means, the singing history of the user ID associated with the logged-in user is updated by the function of the singing history updating means.

  Moreover, when the singing history update means does not update the singing history of the singer, the singing history of the reservation person may be updated.

  In the case where the singing history update unit does not update the singing history of the singer, the user ID is acquired in the case of a configuration including a user ID acquisition and presentation unit that prompts the singer to acquire the user ID. When the user ID is acquired by the singer based on the acquisition presenting means, the singer voice print data and the singing history are linked to the user ID.

  According to the user-specific singing history update system of the present invention, when the singing is actually performed in accordance with the performance of the reserved karaoke piece, the singer's voiceprint data is confirmed and the user is currently logged in. It is determined whether or not the user includes a singer. If the currently logged-in user is not singing, the user is prompted to log in.

  On the other hand, when the user who is currently logged in is singing, the singing history of the karaoke piece is added to the singing history of the singing person by a normal process. Moreover, when login processing is performed by prompting the singer to log in, the singing history of the karaoke piece is added to the singing history of the logged-in user.

  Therefore, since the user who actually sang the karaoke music reserved for music selection can be a singer, an accurate singing history for each user can be created. As a result, when a song selection reservation is made using the user ID of the user who wants to sing to another user who is present, or when a song selection reservation operation is mistakenly performed using another user ID. And the user who is registered in the song selection history with the actual song singer even if other users sing instead of the original song reservation person because the user who selected the song has left the seat As a result, an accurate user-specific singing history is created.

  In addition, when singing is performed by a singer other than the currently logged-in user, the singer who has not logged in is logged in by presenting the singer to log in. , It is possible to perform login processing and reliably update the singing history of the singer.
