An audio read-out device comprises an audio signal generator, a first information receiver, a first information transmitter, a first controller, and a mixed audio signal generator, and when the first information receiver receives audio output enablement information indicating that audio output is disabled, the first controller causes the mixed audio signal generator to generate a mixed audio signal composed of a broadcast audio signal and causes the first information transmitter to transmit the mixed audio signal until the first information receiver receives audio output enablement information indicating that audio output is enabled; and when the first information receiver receives audio output enablement information indicating that audio output is enabled, the first controller causes the mixed audio signal generator to generate a mixed audio signal obtained by mixing a read-out audio signal and a broadcast audio signal, and causes the first information transmitter to transmit the mixed audio signal.
