Abstract: This paper presents, the use of recursive prediction error algorithm(RPE) of training multilayered artificial neural neural(ANN) networks in discrete time non-linear dynamic system identification. As an example, the nonlinear voice dynamic system is modelled based on RPE algorithm. The results provide a good foundation to understand and identify voice model.-
