In an apparatus for speech signal processing, first a coefficient calculation is performed to determine a value for suppressing a change of level of an input signal. Next, an input signal delay is performed to delay the input signal by a time required for the coefficient calculation. Then an output of the input signal delay is multiplied by the value obtained by the coefficient calculation, thereby obtaining an output signal.
