PROBLEM TO BE SOLVED: To reduce time and effort of a volume operation of a user when a voice information output device is connected to a voice reproducing apparatus. SOLUTION: The voice information output device has: a reference signal transmitting means for transmitting a reference signal to the voice reproducing apparatus which is a connection partner; an output signal receiving means for receiving an output signal generated by the voice reproducing apparatus using the reference signal; a differential information calculation means for comparing the output signal received by the output signal receiving means with the reference signal to calculate differential information; and a voice information output means for outputting voice information to the voice reproducing apparatus with gain obtained by compensating gain corresponding to set volume value using the differential information.
