PROBLEM TO BE SOLVED: To provide means for providing easily audible, high quality telephone conversation for a user by muting one of voice output level within two voice output devices.SOLUTION: A radio terminal of the invention is a radio terminal capable of outputting voice output either from two speakers or from one speaker by synthesizing reception signals, by demodulating a direct communication wave using direct communication between radio terminals, and a base station loopback communication wave by repeating communication between radio terminals through a base station. When the two communication waves are simultaneously received, identification numbers of transmission side radio terminal, contained in the two communication waves, are extracted. If both of the two communication waves include identification numbers and the identification numbers match, one voice output is muted, and if only one of the two communication waves contains an identification number, one voice output having the identification number is outputted and the other voice output without an identification number is muted. |
