ABSTRACT:
Improvements in a push button signal receiving device for use in a voice response system, wherein in order to permit a push button signal from a user's telephone terminal to be received even during the period when a responding voice signal is being transmitted through the system, an analyzer for the parameter analysis of the responding voice signal and an inverse filter responsive to the analyzer for flattening the spectrum of the responding voice signal which is mixed into the push button signal are provided, whereby the influence of the responding voice signal mixing into the signal to be applied to a push button signal detector is erased, and the push button signal, which may be feeble in comparison to the responding voice signal, is detected and recognized nevertheless.
