1. A server device that manages a right-to-speak in a case where in a plurality of terminal devices, a terminal device with the right-to-speak is a transmitting side terminal device and a terminal device without the right-to-speak is a receiving side terminal device, the server device comprising:
a receiver that receives, as a response to content of an audio signal received in each of the receiving side terminal devices which has received the audio signal from the transmitting side terminal device, right-to-speak request signals transmitted from the receiving side terminal devices;
a controller that grants the right-to-speak to any one of the receiving side terminal devices based on the right-to-speak request signals received by the receiver; and
a transmitter that notifies the receiving side terminal device to which the right-to-speak has been granted by the controller of the grant of the right-to-speak, wherein
the controller comprises:
an acquisition unit that acquires a reproduction period of the audio signal, a first transmission delay period of from the transmitting side terminal device or the server device to each of the receiving side terminal devices, and a second transmission delay period of from each of the receiving side terminal devices to the server device;
a derivation unit that derives a response period of from when the reproduction of the audio signal ends to when the right-to-speak is requested, for each of the receiving side terminal devices, by subtracting the reproduction period, the first transmission delay period, and the second transmission delay period from timing when the right-to-speak request signal has been received by the receiver; and
a comparing unit that compares the response period of each of the receiving side terminal devices derived by the derivation unit to grant the right-to-speak to any one of the receiving side terminal devices.
