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.}, pdf = {https://publications.idiap.ch/attachments/papers/2001/sacha-ic01sk.pdf}, postscript = {ftp://ftp.idiap.ch/pub/papers/2001/sacha-ic01sk.ps.gz}, ipdmembership={speech}, }
