In a communication terminal apparatus such as a portable telephone, it is made
possible to sound ring tones of good tone quality simply by using arbitrary music
or the like. In a communication terminal that conducts radio communication with
a predetermined station and incorporates a music or speech data reproduction function,
ring tones according to selected data included in previously prepared data for
ring tones is outputted in response to an incoming call when a first mode has been
set, whereas ring tones according to data of a previously set section included
in music or speech data stored in a reproduction function section is outputted,
in response to an incoming call when a second mode has been set.
