Document Type and Number:

Japanese Patent JP2751604

Kind Code:

B2

Abstract:

A level measuring circuit first measures a level of an input speech signal. Next, a coefficient calculating circuit determines a value for suppressing a change of the level of the input speech signal on the basis of an output of the level measuring circuit. Then an input speech signal delay circuit delays the input speech signal by a time required for processing in the level measuring circuit and the coefficient calculating circuit. Finally a multiplying circuit multiplies an output of the input speech signal delay circuit by an output of the coefficient calculating circuit to obtain an output speech signal in which changes in level of the input speech signal are suppressed.
