ICASSP 2001}, volume = II, year = 2001, abstract = "This article presents a new class of constrained and specialized Auto-Regressive (AR) processes. They are derived from lattice filters where some reflection coefficients are forced to zero at a priori locations. Optimizing the filter topology allows to build parametric spectral models that have a greater number of poles than the number of parameters needed to describe their location. These NUT (Non-Uniform Topology) models are assessed by evaluating the reduction of modeling error with respect to conventional AR models.", IPDmembership= "speech", IPDpostScript= "ftp://ftp.idiap.ch/pub/sacha/Publis/ic01sk.ps.gz", IPDpdf ="ftp://ftp.idiap.ch/pub/sacha/Publis/ic01sk.pdf" }
