An adder(103) adds up the input voice signal and deducts the signal received from the LPC mixer(102) to produce an LPC residual signal. A PM calculating device(104) performs a PM by using the LPC residual signal. A first flag determining device(105) determines a flag by using the value of PM received from the PM calculating device(104). An analysis and flag determining unit analyzes frame energy and characteristic and distribution of frequency and then determines a flag.
