A radiotelephone of this invention comprises a sending-speech level varying circuit for varying the level of the sending-speech signal from the microphone and supplying the resulting signal and receiving-speech level varying means for varying the level of the receiving-speech signal demodulated by receiving means and supplying the resulting signal to the speaker, as well as a talking-mode setting section and a gain control circuit. At the talking-mode setting section, either the handset talking mode or the hand-free talking mode is set. At the gain control circuit, the gains of the sending-speech level varying circuit and receiving-speech level varying circuit undergo variable control according to the talking mode set by the talking-mode setting section. The gain control is carried out in such a manner that the gain becomes a first specific value when the handset talking mode has been set, and a second specific value larger than the first value when the hand-free talking mode has been set.
