Abstract

A speech recognition apparatus for a speech recognition answering system which uses telephone channels and having a function of detecting a PB (PUSH BUTTON) signal. A speech recognition unit recognizes a speech signal from an input signal, while a PB detection unit detects a PB signal from an input signal. A control unit automatically determines whether an input signal is a speech signal or whether it is a PB signal on the basis of the outputs of the speech recognition unit and PB detection unit.
