  • Method and apparatus for replacing a voice with an original lead singer's voice on a karaoke machine
    Patent number: 6148086
    Abstract: A voice replacing method and system that uses the volume of the karaoke user's voice to control the volume of the lead singer's original vocal outputted to the audience. The volume of an original lead singer's voice is determined by the volume or vocal-amplitude level of the karaoke user's voice. The vocal-amplitude of the karaoke user is sensed using a vocal sensor. A vocal-amplitude digital waveform is created corresponding to the vocal-amplitude. A smoothed exponential waveform is created byan amplitudefollower corresponding to the digital waveform. The volume of the original lead singer's voice is adjusted by a sliding balance according to the smoothed exponential waveform. This exponential waveform allows for a continuous and smooth volume adjustment of the original lead singer's voice according to changes in volume of the karaoke user's voice.
