As an effort to make prosody useful in spontaneous speech recognition, we adopt a quasi-continuous prosodic annotation and accordingly design a prosody-dependent acoustic model to improve ASR performances. We propose a variable-parameter Hidden Markov Models, modeling the mean vector as a function of the prosody variable through a polynomial regression model. The prosodically-adapted acoustic m...

this paper presents a novel control approach used in shunt active power filter based on variable structure control combined with random pwm technique (rvsc) that provides robust, fast, and more favorable performance for active power filter. this control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...

This paper mainly expounds that using the WINSOCK controller which is provided by VB6.0 to program the procedures in the coop intelligent control system, it introduces the character of the TCP protocol and the UDP protocol, and according to the demands of the system environment to choose the suitable protocol. This system uses the WINSOCK controller and the UDP protocol for network communicatio...

INTRODUCTION Acoustic evaluation of alaryngeal voices is among the most prominent issues in speech analysis field. In fact, many methods have been developed to date to substitute the classic perceptual evaluation. The Aim of this study is to present our experience in erygmophonic speech objective assessment and to discuss the most widely used methods of acoustic speech appraisal. through a pros...

This paper addresses the design of control charts for both variable ( x chart) andattribute (u and c charts) quality characteristics, when there is uncertainty about the processparameters or sample data. Derived control charts are more flexible than the strict crisp case, dueto the ability of encompassing the effects of vagueness in form of the degree of expert’spresumption. We extend the use o...

Understanding spoken language requires mapping acoustic input onto stored phonological and lexical representations. Speech tokens, however, are notoriously variable: they fluctuate within speakers, across speakers, and in different acoustic environments. As listeners, we must therefore perceive speech in a manner flexible enough to accommodate acoustic signals that imperfectly match our expecta...

In this paper an emotionally justified approach for controlling sound with physiology is presented. Measurements of listeners’ physiology, while they are listening to recorded music of their own choosing, are used to create a regression model that predicts features extracted from music with the help of the listeners’ physiological response patterns. This information can be used as a control sig...

The past decade has produced an increased ecological interest in sonic environments, or soundscapes. However, despite this rise in interest and technological improvements that allow for long-term acoustic surveys in various environments, some habitats' soundscapes remain to be explored. Ponds, and more generally freshwater habitats, are one of these acoustically unexplored environments. Here we...
