Abstract

The method involves calculating positions of excitation pulses in several calculation stages in accordance with a first method. The positions of the excitation pulses in several calculation steps are calculated in accordance with a second method. Each stage has a starting point from one of several positions (mi,mk,mr) calculated in accordance with the first method to obtain one of the pulse placements. The proportion between the number of calculation stages is chosen according to the first and second methods respectively to obtain the least complexity for a certain speech quality.
