Recently, a quality of motors is inspected by human ears. In this paper, I propose two systems using a method of speech recognition for automation of the inspection. The first system is based on a method of linear processing which uses K-means and Nearest Neighbor method, and the second is based on a method of non-linear processing which uses neural networks. I used motor sounds in these system...

In this project, all known acoustical correlates for prominence at the sentence level, such as F0, intensity, duration and spectral quality will be investigated. The speech material will be selected from the Dutch Polyphone corpus as recorded by SPEX and KPN Research Leidschendam. The sentences from this corpus are suitable to investigate systematically (with high speaker variability) the acous...

The estimation of oceanic environmental and acoustical fields is considered as a single coupled data assimilation problem. The four-dimensional data assimilation methodology employed is Error Subspace Statistical Estimation. Environmental fields and their dominant uncertainties are predicted by an ocean dynamical model and transferred to acoustical fields and uncertainties by an acoustic propag...

A room may be used for a wide variety of performances and presentations. Each use places different acoustical requirements on the room. We desire a method of electronically controlling the acoustical properties of a room so that one physical space can accommodate various uses. A virtual acoustic room is a room equipped with speakers, microphones and signal processors that functions as an intera...

A randomized prospective controlled study was made in order to find out if voice related acoustical measures show usable predictive pathologies in patients with laryngo-pharyngeal reflux (LPR). The used acoustical program was an advanced MDVP (multi-dimensional voice program) by Laryngograph Ltd. which routinely adjusts to well defined sustained tones measures as well as reading of a standard t...

Fall 2006 Meeting, joint with the Acoustical Society of Japan (Honolulu, Hawaii). The Technical Committee on Acoustical Oceanography AO sponsored two special sessions: 1 “Acoustic scattering by aquatic organisms,” organized by Ken Foote Woods Hole Oceanographic Institution and Masahiro Furusawa from the Acoustical Society of Japan; and 2 “Ocean acoustic tomography for coastal and deep water app...

The paper concerns the quest to find acoustical parameters that describe properties of vocal fold functioning from professional singing to voice pathologies. Improved data handling within the framework of phonetogram recordings has been used to arrive at a better understanding of what acoustical parameters could tell us about vocal registers.

In recent years many approaches have been developed to address the problem of robust speaker recognition in adverse acoustical environments. In this paper we propose a robust auditory-based feature extraction method for speaker recognition according to the characteristics of the auditory periphery and cochlear nucleus. First, speech signals are represented based on frequency selectivity at basi...

Computational Auditory Scene Analysis (CASA) aims to model our ability to structure our acoustical environment. In a CASA context, this paper deals with a method for time-frequency labeling based on harmonic properties. The method is based on a classical pitch extraction algorithm, termed the « zerocrossing method », which is known to be particularly sensitive to any kind of interference. This ...
