This volume contains the proceedings of NOLISP 2009 an ISCA Tutorial and Workshop on
Non-Linear Speech Processing held at the University of Vic (- talonia Spain) during June 25-27
2009. NOLISP2009wasprecededbythreeeditionsofthisbiannualeventheld2003 in Le Croisic (France)
2005 in Barcelona and 2007 in Paris. The main idea of NOLISP workshops is to present and
discuss new ideas techniques and results related to alternative approaches in speech
processing that may depart from the mainstream. In order to work at the front-end of the
subject area the following domains of interest have been de?ned for NOLISP 2009: 1. Non-linear
approximation and estimation 2. Non-linear oscillators and predictors 3. Higher-order
statistics 4. Independent component analysis 5. Nearest neighbors 6. Neural networks 7.
Decision trees 8. Non-parametric models 9. Dynamics for non-linear systems 10. Fractal methods
11. Chaos modeling 12. Non-linear di?erential equations The initiative to organize NOLISP 2009
at the University of Vic (UVic) came from the UVic Research Group on Signal Processing and was
supported by the Hardware-Software Research Group. We would like to acknowledge the ?nancial
support obtained from the M- istry of Science and Innovation of Spain (MICINN) University of
Vic ISCA and EURASIP. All contributions to this volume are original. They were subject to a
doub- blind refereeing procedure before their acceptance for the workshop and were revised
after being presented at NOLISP 2009.
