ABSTRACT:
An auto voice changing apparatus receives music from a stereo or multi-sound, digital or analog recording and either plays the recorded music as is, or uses the recorded music as instrumental accompaniment by eliminating the vocal sounds from the reproduced music and substituting vocal sounds provided through a microphone. The control is based solely on a single auto voice switch, control information from the recording, and detection of vocal sounds from the microphone.
