PROBLEM TO BE SOLVED: To easily adjust the respective volume levels of an audio and a receiving voice by speech simultaneously reproduced in the speech. SOLUTION: In non-speech communication, only the audio is reproduced without reproducing the received voice, a CPU 101 sets the reproducing volume level of an audio reproducing sound volume adjusting circuit 302 to the maximum value (MAX). In speech communication, the CPU 101 decides the respective setting values of PDA reproducing sound volume and telephone receiving voice volume based on the volume balance between an audio reproducing sound and the receiving voice previously specified by a user. The setting values are set to the audio reproducing sound volume adjusting circuit 302 and a telephone voice volume adjusting circuit 301, respectively. COPYRIGHT: (C)2003,JPO
