Models and analysis of vocal emissions for biomedical applications

This book of Proceedings collects the papers presented at the 4th International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications, MAVEBA 2005, held 29-31 October 2005, Firenze, Italy. The workshop is organised every two years, and aims to stimulate contacts between specialists active in research and industrial developments, in the area of voice analysis for biomedical applications. The scope of the Workshop includes all aspects of voice modelling and analysis, ranging from fundamental research to all kinds of biomedical applications and related established and advanced technologies

Models and Analysis of Vocal Emissions for Biomedical Applications

The MAVEBA Workshop proceedings, held on a biannual basis, collect the scientific papers presented both as oral and poster contributions, during the conference. The main subjects are: development of theoretical and mechanical models as an aid to the study of main phonatory dysfunctions, as well as the biomedical engineering methods for the analysis of voice signals and images, as a support to clinical diagnosis and classification of vocal pathologies

Models and analysis of vocal emissions for biomedical applications: 5th International Workshop: December 13-15, 2007, Firenze, Italy

The MAVEBA Workshop proceedings, held on a biannual basis, collect the scientific papers presented both as oral and poster contributions, during the conference. The main subjects are: development of theoretical and mechanical models as an aid to the study of main phonatory dysfunctions, as well as the biomedical engineering methods for the analysis of voice signals and images, as a support to clinical diagnosis and classification of vocal pathologies. The Workshop has the sponsorship of: Ente Cassa Risparmio di Firenze, COST Action 2103, Biomedical Signal Processing and Control Journal (Elsevier Eds.), IEEE Biomedical Engineering Soc. Special Issues of International Journals have been, and will be, published, collecting selected papers from the conference

Generalized Variogram Analysis of Vocal Dysperiodicities in Connected Speech

Multiband frame-based acoustic cues of vocal dysperiodicities in disordered connected speech

Two variants of multiband segmental signal-to-dysperiodicity ratio are used to summarize vocal dysperiodicities in connected disordered speech and their performance is compared to that of the conventional global signal-to-dysperiodicity ratio. Acoustic analysis is carried out by means of a generalized variogram to extract vocal dysperiodicities. The corpus comprises four French sentences as well as vowels [a] produced by 22 male and female normophonic and dysphonic speakers. It is shown that the multiband signal-to-dysperiodicity ratios correlate better with perceptual scores of hoarseness than the global signal-to-dysperiodicity ratio. The highest correlations are achieved by the acoustic marker based on linear regression analysis of the segmental signal-to-dysperiodiciy ratios in different non-overlapping frequency bands. The perceptual scores are based on comparative judgments by six listeners of pairs of speech tokens. © 2006 Elsevier Ltd. All rights reserved.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
