This quantity comprises the lawsuits of NOLISP 2009, an ISCA instructional and Workshop on Non-Linear Speech Processing held on the college of Vic (- talonia, Spain) in the course of June 25-27, 2009. NOLISP2009wasprecededbythreeeditionsofthisbiannualeventheld2003 in Le Croisic (France), 2005 in Barcelona, and 2007 in Paris. the most proposal of NOLISP workshops is to provide and talk about new rules, ideas and effects with regards to substitute methods in speech processing that could leave from the mainstream. to be able to paintings on the front-end of the topic region, the next domain names of curiosity were de?ned for NOLISP 2009: 1. Non-linear approximation and estimation 2. Non-linear oscillators and predictors three. Higher-order facts four. self sufficient part research five. Nearest friends 6. Neural networks 7. choice bushes eight. Non-parametric types nine. Dynamics for non-linear structures 10. Fractal tools eleven. Chaos modeling 12. Non-linear di?erential equations The initiative to arrange NOLISP 2009 on the college of Vic (UVic) got here from the UVic study staff on sign Processing and was once supported via the Hardware-Software learn staff. we want to recognize the ?nancial aid received from the M- istry of technology and Innovation of Spain (MICINN), college of Vic, ISCA, and EURASIP. All contributions to this quantity are unique. They have been topic to a doub- blind refereeing approach prior to their reputation for the workshop and have been revised after being awarded at NOLISP 2009.

It is well known that the shape of glottal closing is a strong correlate of spectral tilt and is important for studying voice quality. g. time and pitch scaling). Phase-Based Methods for Voice Source Analysis 25 5 Conclusions In this article recent work by the authors on voice source analysis and synthesis using methods based on the spectral phase or instantaneous phase are presented. The main results obtained are the following: • • • • • • • • detailed and careful consideration of the glottal flow shows that glottal flow models can be represented by causal-anticausal (mixed phase) filters the link between time-domain and spectral domain parameters can be worked out, equations are available for most time domain glottal flow models a new glottal model in the spectral domain is proposed for speech synthesis (Causal-Anticausal Linear Model, or CALM).
