ABSTRACT:
Provided is a cellular phone enabling improvement of the level of a sense of hearing of a pseudo noise which is generated when there exists no voice signal. In the cellular phone, frame type information included in a baseband signal “in” is identified by the frame type identification unit71and when the frame type information represents pseudo noise information, a pseudo noise signal generated by the AMR (Adaptive Multi-Rate) decoder72with an internal pseudo noise generator is output to the call receiver unit43with its level reduced by a predetermined amount by the signal level change amount calculation unit74and the signal level change unit73, while when the frame type information represents a voice signal, the voice signal decoded by the AMR (Adaptive Multi-Rate) decoder72with an internal pseudo noise generator is output to the call receiver43with its level unchanged.
