Abstract :
This paper discusses the robustness of the linear prediction whose minimization process is based on a least absolute error criterion. Due to such robustness in the preciseness of prediction, we can estimate a pole-zero model of speech signals and approximate better the spectral envelope compared to that obtained by traditional linear prediction
