Abstract
A karaoke apparatus produces a karaoke accompaniment which accompanies a singing voice of an actual player, and concurrently creates a harmony voice originating from a virtual player. In the karaoke apparatus, a memory device stores voice information of the virtual singer. An input device collects the singing voice of the actual player. An analyzing device analyzes an audio frequency of the collected singing voice. A synthesizing device processes the stored voice information based on the analyzed audio frequency to synthesize the harmony voice having another audio frequency which is set in harmony with the analyzed audio frequency. An output device mixes the collected singing voice and the synthesized harmony voice with each other, and outputs the mixed singing and harmony voices along with the karaoke accompaniment. In one preferred embodiment, the memory device stores the voice information in the form of a sequence of phonetic elements that are successively sampled syllable by syllable from a singing voice of the virtual player.
