KARAOKE ACCOMPANIMENT SOUND PRODUCING DEVICE

PROBLEM TO BE SOLVED: To provide the karaoke accompaniment sound producing device which provide a variety of usages by converting a singing voice into an accompaniment sound. SOLUTION: When a musical instrument sound is specified at an operation part or by a remote control and the voice of an accompaniment part that a singer sings is inputted from a voice input part 10 such as a microphone, the karaoke accompaniment sound producing device 1 converts the voice into a voice signal by the voice input part 10 and outputs it to a parameter extraction part 20. At the parameter extraction part 20, its pitch data extraction part 21 extracts pitch data corresponding to the rhythm of an accompaniment sound from the voice signal and outputs them to an accompaniment generator 41, whose sound volume data extraction part 22 extracts sound volume data corresponding to the level of the accompaniment sound from the voice signal and outputs them to an accompaniment sound generator 42. At an accompaniment sound producing part 40, a musical instrument sound specification part 42 reads specified timbre data out of a storage part 30 and outputs them to the accompaniment sound generator 41, which puts the timbre data and the pitch data and sound volume data outputted from the parameter extraction part 20 together one over another to produce an accompaniment sound like a musical instrument sound with the specified timbre, thereby reinforcing and outputting it through an output part.
