ABSTRACT:
A karaoke apparatus operates according to a song data for presenting a karaoke performance composed of an instrumental accompaniment and a back chorus under a designated condition determined in terms of either of a tempo and a pitch. In the karaoke apparatus, a data source provides a song data which contains a musical tone data, a synthetic voice data and a real voice data. An input panel is operated for designating either of a regular condition and an irregular condition. A tone generator processes the musical tone data to generate an instrumental accompaniment, and concurrently processes the synthetic voice data to generate a false back chorus. A voice decoder decodes the real voice data to reproduce a natural back chorus. A sequencer operates under the regular condition for effectuating the voice decoder to sound the natural back chorus along with the instrumental accompaniment, and otherwise operates under the irregular condition for suppressing the voice decoder to silence the natural back chorus while allowing tone generator to sound the false back chorus along with the instrumental accompaniment.
