Abstract
The purpose of this work is to show the importance of an adequate generation of the excitation signal for the performance of bandwidth extension algorithms for speech signals. Two previously proposed methods of obtaining the excitation signal are analyzed and, based on this analysis, a new method is proposed. The influence of each method in the quality of the reconstructed wideband speech signal is evaluated by quantitative parameters of speech quality.
