A voice communication method of performing mutual communication between a plurality of terminal devices including a first terminal device as a caller and a second terminal device as a responder, via a server device connected via a network, the method comprising:

• transmitting by the first terminal device according to a transmission operation by a user, a voice signal and identification information of the second terminal device, as a communication partner, to the server device,
• transferring by the server device the voice signal transmitted from the first terminal device to the second terminal device,
• continuously counting by the server device a number of simultaneous receptions of the voice signals,
• transferring by the server device, in a case where the number of simultaneous receptions reaches a predetermined restriction value, the received voice signal with transmission restriction information attached thereto, to the second terminal device, and
• performing by the second terminal device transmission restriction in which the second terminal device does not transmit a voice signal even when a transmission operation is performed by the user, during reception of a voice signal having the transmission restriction information attached thereto.

A non-transitory computer-readable recording medium storing a voice communication program, the program causing a controller of a server device that communicates with a plurality of terminal devices including a first terminal device as a caller and a second terminal device as a responder, via a network, to execute instructions comprising:

• receiving a voice signal transmitted from the first terminal device;
• continuously counting a number of simultaneous receptions of the voice signals;
• and
• transferring a received voice signal to the second terminal device, the transferring including transferring, in a case where the number of simultaneous receptions reaches a predetermined restriction value, the received voice signal with transmission restriction information attached thereto, to the second terminal device.
