LDP karaoke apparatus with music tempo adjustment and singer evaluation capabilities

Abstract

The present invention relates to a laser disk player having a karaoke capability, and more particularly to a laser disk player karaoke apparatus that compares the tempo of a musical selection reproduced from a laser disk with the tempo at which a user is singing, in order to permit evaluation of singing ability. When the singer's tempo does not correspond with the tempo of the music, the apparatus can match the music's tempo reproduced from the laser disk to the user's singing tempo. Particularly, if an aural synchronizing signal is recorded on the laser disk to indicate where singing of a song should start, a time difference is obtained during playback, indicating the time between the aural synchronizing signal and an aural signal input by a user via an external microphone. The time difference is used to correct the playback tempo and to assess the user's singing ability. The laser disk player karaoke apparatus of the present invention, therefore, can prevent the discomfort resulting from discordant music by correcting the disagreement between the user's singing measure and the music's measure. The apparatus can also easily help the user evaluate his or her own singing ability by providing appropriate data and can thereby help the user improve poor singing habits.
