Abstract
An audio communication system includes a generation unit that superimposes an addition sound having a volume level determined on the basis of a voice acquired by a voice acquisition unit on an input voice acquired by the voice acquisition unit of a transmission terminal and generates a synthesis sound and a transmission unit that transmits a signal of the synthesis sound generated by the generation unit to a reception terminal.

15. An audio transmission terminal comprising:
-
a generation unit that superimposes an addition sound having a constant volume level on an input voice sequentially acquired by a voice acquisition unit, and generates a synthesis sound; a transmission unit that sequentially transmits a signal of the synthesis sound generated by the generation unit to an audio reception terminal; a retransmission request acquisition unit that acquires a retransmission request of a defective portion of the input voice detected on the basis of the addition sound from the audio reception terminal; a retransmission unit that retransmits a signal of the input voice corresponding to the defective portion to the audio reception terminal according to the retransmission request; and a control unit that controls the transmission unit, such that the signal of the synthesis sound is not transmitted from the transmission unit, in a retransmission time zone to be a time zone in which the signal of the input voice corresponding to the defective portion is transmitted from the retransmission unit. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. An audio transmission terminal comprising:
-
a generation unit that superimposes an addition sound having a constant volume level to detect a defective portion of an input voice sequentially acquired by a voice acquisition unit on the input voice, and generates a synthesis sound; a transmission unit that sequentially transmits a signal of the synthesis sound generated by the generation unit to an audio reception terminal; and a communication quality detection unit that detects a communication quality between the audio transmission terminal and the audio reception terminal, wherein the generation unit changes the volume level of the addition sound on the basis of the detected communication quality, instead of setting the volume level of the addition sound to be constant, when the communication quality detected by the communication quality detection unit is less than a reference value.
