Abstract: In a portable telephone device, a desired telephone number selected by an user from all or a part of telephone directory list is converted into audio data by an audio data converting circuit to transmit it to a communication partner, so that the telephone number corresponding to the audio data can be uttered as a voice at the partner side who receives the audio data. Thereby, a portable telephone device with improved user ability can be realized.
