Abstract

In this study, for analysis speech signal the 10th order LPC synthesis filter is split into five 2nd order filters to avoid the nonlinear interactions of the poles. This novel algorithm allows us to reconstruct the wideband speech signal from the narrowband one by using the relationship between AR coefficients and its corresponding analog poles. The relationships between AR parameters and the continuous poles are presented.
