A karaoke apparatus evaluates a singer's performance by employing: a microphone for converting the singer's voice into a electrical voice signal; a first analogue to digital (A/D) converter for converting the electrical voice signal into a digitized voice signal; a audiovisual equipment for producing the accompanying music; a second A/D converter for digitizing the accompanying music to produce a digitized accompaniment signal; and a performance evaluator for measuring the difference between the accompanying music and the corresponding karaoke singer's voice to produce a score for the karaoke singer's singing performance.
