PURPOSE:To obtain the output of an artificial duet with the opposite sex by using the voice input of one person. CONSTITUTION:An input voice signal is inputted to an interval converter 14 through a preamplifier 12. The interval converter 14 increases the pitch of the input voice signal by one octave and outputs the signal. The output of the interval converter 14 after having its level adjusted by a level adjuster 15 is added by an adder 13 to the input voice signal and the resulting signal is outputted. When a male voice signal is inputted, a signal having the female range is outputted from the interval converter 14 and the artificial duet output of the male and female is obtained from the adder 13. |
