1. An audio read-out device connected via a network to an audio output device that outputs a read-out audio signal, the audio read-out device comprising:

  • an audio signal generator configured to generate the read-out audio signal from text information;

    a first information receiver configured to receive audio output enablement information from the audio output device via the network;

    a first information transmitter configured to transmit the read-out audio signal generated by the audio signal generator, to the audio output device via the network;

    a first controller configured to, when the first information receiver receives audio output enablement information indicating that audio output is disabled, cause the first information transmitter to wait to transmit the read-out audio signal until the first information receiver receives audio output enablement information indicating that audio output is enabled, and to, when the first information receiver receives audio output enablement information indicating that audio output is enabled, cause the first information transmitter to transmit the read-out audio signal; and

    a mixed audio signal generator configured to mix the read-out audio signal generated by the audio signal generator and a broadcast audio signal to generate a mixed audio signal;

    wherein;

    the first information transmitter outputs to the audio output device the mixed audio signal generated by the mixed audio signal generator, andwhen 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 the 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 the read-out audio signal and the broadcast audio signal, and causes the first information transmitter to transmit the mixed audio signal.
