The apparatus has a karaoke function including digital signal processor means separating an aural synchronizing signal, an audio signal and a video signal from a digital signal reproduced from the laser disk, and a monitor for displaying the processed audio and video signals. The apparatus comprises: a tempo difference detector for detecting a time difference between a user's aural signal input from an external source and the aural synchronizing signal derived by digitally processing information reproduced from the laser disk in the digital signal processor; and a reproduced signal speed controller for controlling output speed of the audio signal reproduced from the laser disk and output by the digital signal processor in accordance with the time difference detected by the tempo difference detector.
