Abstract
The speech decoding apparatus decodes a speech signal that is coded into a plurality of speech parameters including an excitation parameter, using the excitation parameter. The controller controls an output speech volume of the decoded speech signal according to a predetermined gain parameter. At this point, the gain parameter is corrected according to an energy of the speech signal corresponding to the excitation parameter. The controller controls the output speech volume corresponding to the gain parameter only when the energy of the speech signal corresponding to the excitation parameter is within a predetermined range.
