Abstract
In a karaoke apparatus, a tone generator responds to a request of a karaoke song for generating musical tones of the karaoke song having a given gender so as to accompany a live singing voice having an actual gender. A voice changer is provided for selectively conducting either of male-to-female conversion effective to upward shift a pitch of the live singing voice and female-to-male conversion effective to downward shift a pitch of the live singing voice. A voice analyzer is provided for analyzing the live singing voice to determine the actual gender of the live singing voice. A parameter generator is provided for comparing the determined actual gender of the live singing voice with the given gender of the karaoke song so as to control the voice changer to select either of the male-to-female conversion and the female-to-male conversion if the actual gender differs from the given gender so that the pitch of the live singing voice can be shifted to match the given gender of the karaoke song.
