Abstract

PURPOSE:To receive the signal from a telephone set without a private receiver for a pushphone signal, by providing a voice analyzing and parameter extracting part, a pushphone signal discriminating part, and a pushphone signal deciding part in a voice recognizing part. CONSTITUTION:An input signal is branched into two through a preprocessing part 1 and an A/D converting part 2, and one is given to a maximum power detecting part 5 and an analyzed section detecting part 6 to detect a part of a comparatively high level in the input signal, and the other is subjected to a calculation of parameters such as an auto-correlation function of a short section in a parameter extracting part 3 and is inputted to a buffer memory 4. Parameters in a prescribed level section are supplied to a variation calculating part 13, and a variation of the parameter time series is calculated and is decided by a deciding part 14. When the pushphone is discriminated on a basis of the fact that the pushphone signal has the level fluctuated less than the human voice, time series information is calculated by calculating parts 15 and 16, and respective calculation results are compared with a prescribed threshold in deciding parts 17 and 18, and pushphone information is obtained from a circuit 19.
