Specifically, a karaoke system that records singing voices sung along with karaoke accompaniment music and can use the recorded work for listening to the user by any karaoke device, and a karaoke constituting the communication karaoke system The present invention relates to a device and a work management server.

  A service for synthesizing the singing voice of a karaoke singer with karaoke accompaniment music and recording it on a recording medium such as a CD-R is well known. For example, Japanese Patent Laid-Open No. 2000-382130 discloses a technique for recording karaoke accompaniment music and singing voices sung along with the music onto a recording medium in consideration of copyright.

  In Japanese Patent Laid-Open No. 2002-287777, a karaoke karaoke accompaniment music and a singing voice are created as a recording file of a predetermined format and temporarily stored in response to a case where the singing fails, and a user instruction In accordance with the above, a karaoke recording apparatus for transferring to a portable recording medium is disclosed.

  Japanese Patent Application Laid-Open No. 2005-241743 includes a recording work deposit system that transmits a singing voice recording of a singing voice to a predetermined computer managed by an operator instead of recording it on a CD-R or the like and uses it appropriately. A karaoke apparatus is disclosed, and according to this karaoke apparatus, it is possible to deposit a singing recording work when the singing is performed best.

=== Invention ===
The inventors of the present invention have focused on the fact that karaoke is often enjoyed by friendly friends. And if you want to go to karaoke with your friends. We assumed that one of the friends was inconvenient and could not go to karaoke together. In such a case, other friends should feel a little lonely when they think of a friend who could not come together. However, if you can hear the voices of friends who could not participate even if all of your friends were not in this way, the loneliness would be distracted to some extent, and if you talked about the people who could not participate by listening to the singing voice, The karaoke place may be exciting. Therefore, I thought about playing back the recorded voice (song recording work) when the absentee sang at karaoke. Someone at a karaoke venue can show their song recordings to their friends on the spot, give a song recording to a friend who is far away, and the friend listens to the gift at a karaoke store, etc. There are many requests to play song recordings at karaoke.

  However, it is also surprising that a medium such as a CD-R on which a song is recorded is played using a player at a karaoke place. When playing back a song recorded by a person who is not at a karaoke venue, it is also necessary to prepare a recorded medium in advance. There is a high possibility that a device for reproducing sound recorded on a medium such as a CD player is not installed in a karaoke place, or the karaoke device does not have a reproduction function.

  Therefore, utilizing the technique described in the above Japanese Patent Application Laid-Open No. 2005-241743, the voice recorded by the karaoke device is deposited on a computer on the network, and the recorded song recording is karaoke. I came up with the idea of downloading to the device and playing it back. Moreover, if the song recording work can be easily created and deposited, and the song recording work can be instructed to be played in the same manner as the karaoke music performance reservation procedure, the creator of the song recording work will actually be on the spot. I thought that I could taste the atmosphere as if I was in a song, and suddenly play a song recording without being noticed by other friends. The present invention was created in anticipation of such an effect.
