Abstract

PROBLEM TO BE SOLVED: To make a transmitted voice a clear voice, when it is difficult to listen to and to perform communication by performing a frequency conversion of voice and selecting whether to transmit the voice that is different from the original voice or to transmit the original voice as it is. SOLUTION: After a voice inputted from a microphone of a handset 8 is subjected to digital conversion in an A/D converting part 7, it is processed by a voice codec part 6 and is converted into a voice that is different from the original voice in such a manner that a frequency conversion circuit 10 changes the frequency of the voice. Whether to cover or not to convert the voice is selected by a control signal 11, with which a control circuit 3 processes an input signal from an inputting part 4 and voice data that undergoes frequency conversion or voice data that does not undergo frequency conversion is selected by a selector 9 and is transferred to a radio circuit 2. The circuit 2 modulates the voice data and is transmitted from an antenna 1. It is possible to change a voice and to use not only the original voice but also a frequency conversion voice for an automatic answering message, when a telephone call comes from the other party who is not intended.
