Abstract
Official abstract text for this publication.
A voice signal processing apparatus and a voice signal processing method are provided. A filtering loudness gain of a filter signal of each frequency band is adjusted according to a wide dynamic range compression curve without an upper output loudness limit. The filtering loudness gain of each frequency band is reduced by lowering a gain decrease adjustment value, so as to reduce a loudness of a loudness adjusted filter signal, and thus a loudness of an output voice signal is lower than a first threshold value.
First claim
Opening claim text (preview).
What is claimed is: 1. A voice signal processing apparatus, comprising: a filtering part receiving an input voice signal and filtering the input voice signal to generate a plurality of filter signals of different frequency bands; and a processing part detecting loudnesses of the filter signals to obtain a plurality of filter loudnesses, and calculating filtering loudness gains of the frequency bands according to the filter loudnesses and wide dynamic range compression curves cor…
