Abstract

PURPOSE:To detect a dial pulse signal which is misinputted as a PB signal and input data again by a user through another means. CONSTITUTION:A dial pulse detection part 7 and a 2nd speech synthesis part 8 are provided and when the dial pulse detection part 7 detects dial pulses, the user is prompted by a voice to input the data. It is thought that the PB signal can be outputted by a dial pulse type key telephone set, and the user sends out the dial pulses at the time of the data input; and the user who can not input the data is informed of the output of the dial pulses and voice input is propmpted, thereby enabling to input the data to the user who can not input the data before.
