Abstract  Abstract

A method according to one embodiment includes encoding a first frame and a second frame of a speech signal to produce corresponding first and second vectors wherein the first vector represents a spectral envelope of the speech signal during the first frame and the second vector represents a spectral envelope of the speech signal during the second frame. The method includes quantizing a vector based on the first vector; adding to the second vector a value based on a scaled quantization error of the first vector to obtain a vector sum; and quantizing the vector sum.
