Abstract
An encoder () and system () for processing a sequence of input vectors (yto y) obtained from a speech signal. A filter () has both a current slowly evolving filter estimate output () and a previous slowly evolving filter estimate output (). The current slowly evolving filter estimate output () provides vectors of current filtered estimate element values of a slowly evolving component of the sequence of input vectors (yto y) and the previous slowly evolving filter estimate output () provides vectors of previous filtered estimate element values of the slowly evolving component of said sequence of input vectors (yto y). There is also a parameter estimator (), smoother module () and slowly evolving component encoder () that provides a digitized encoded slowly evolving component of the speech signal.
