Patent abstract
A method for calculating the amplication factor, which co-determines the volume, for a speech signal transmitted in encoded form includes dividing the speech signal into short temporal signal segments. The individual signal segments are encoded and transmitted separately from each other, and the amplication factor for each signal segment is calculated, transmitted and used by the decoder to reconstruct the signal. The amplication factor is determined by minimizing the value E(g_opt2)=(1−a)*f1(g_opt2)+a*f2(g_opt2), the weighting factor a being determined taking into account both the periodicity and the stationarity of the encoded speech signal.
