Abstract  Abstract

1. A signal processing method comprising! encoding the first frame and the second frame of the speech signal to form the first and second vectors, the first vector representing the spectral envelope of the speech signal during the first frame, and the second vector representing the spectral envelope of the speech signal during the second frame; ! generating a first quantized vector, said formation including quantizing a third vector that is based on at least a portion of the first vector; ! calculating a quantization error of the first quantized vector; ! computing a fourth vector, said calculation including summing a scaled version of a quantization error with at least a portion of a second vector; and! quantization of the fourth vector. ! 2. The method according to claim 1, wherein said calculation of a quantization error includes calculating a difference between a first quantized vector and a third vector. ! 3. The method according to claim 1, wherein said calculation of a quantization error includes calculating a difference between the first quantized vector and at least a portion of the first vector. ! 4. The method according to claim 1, further comprising calculating a scaled quantization error, said calculation comprising multiplying a quantization error by a scale factor, the scale factor being based on the distance between at least a portion of the first vector and a corresponding part of the second vector. ! 5. The method according to claim 4, in which each of the first and second vectors contains many frequencies of spectral lines. ! 6. The method according to claim 1, in which each of the first and second vectors contains
