PROBLEM TO BE SOLVED: To provide a karaoke machine capable of correcting its voice without spoiling singing expression by a singing person. SOLUTION: A karaoke sequencer section 301 automatically plays a musical piece and displays words of the song by processing music data stored in a storage device 20. An interval correction section 304 detects an original pitch which is the pitch of voice data input from an ADC 10, and outputs a corrected voice data in which the pitch is corrected. A MIX ratio control section 305 specifies a reference pitch of the voice to be pronounced from the MIDI data of a melody input from the sequencer section 301. When the reference pitch is outside of a predetermined pitch range and the original pitch is outside of the reference pitch from the viewpoint of the pitch range, the MIX ratio corresponding to pitch difference between them is set to a mixer 306, and the voice data from the ACD 10 is mixed with the corrected voice data.
