Abstract:
PURPOSE:To satisfactorily sing even an unaccustomed song to an accompaniment by providing a controller, which detects the start point of a vocal signal and outputs the vocal signal for only a certain time after the start point, to make it easy that the singer find an opportunity to start singing. CONSTITUTION:A buffer amplifier 18 - a one shot multivibrator 24 constitute a controller 25 which detects the start point of the vocal signal outputted through a preamplifier 4 and outputs the vocal signal for only a certain time after the start point. The controller 25 which indicates the singing start is provided to make it possible that the singer find easily an opportunity to start singing. When this controller 25 is used, a moving terminal 9' of a variable resistor 9 is moved upward in the figure to prepare for loudening of only an accompaniment signal. If the time constant of an integrating circuit 22 is adjusted properly, a Schmitt circuit 23 is reset after the first words are terminated, and the same singing start indication as the first words is given at the beginning of the second words.
