Abstract
A long-term analysis of an input speech signal is carried out to adaptively select parameters of a pitch synthesis filter in respective variation ranges. Successively selected values of said parameters are processed to estimate maximum magnitudes of an error component of the output signal of the pitch synthesis filter. The variation range of at least one of said parameters is determined on the basis of the estimated maximum magnitudes.
