Aud-SWIPE-P: A parallelization of the Aud-SWIPE pitch estimation algorithm using multiple processes and threads
(Acta Press. Artificial Intelligence and Applications / 794: Modelling, Identification and Control / 795: Parallel and Distributed Computing and Networks / 796: Software Engineering / 792: Web-based Education (AIA 2013), 2013-02-11)
In this work we implement a parallel version of the pitch estimation algorithm Aud-SWIPE. The new implementation, Aud-SWIPE-P produces a remarkable acceleration, making it usable in applications where it was not efficient ...
Improved voice activity detection algorithm using wavelet and support vector machine
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2010)
This paper proposes an improved voice activity detection (VAD) algorithm using wavelet and support vector machine (SVM) for European Telecommunication Standards Institution (ETS1) adaptive multi-rate (AMR) narrow-band (NB) ...
Classification of lexical stress using spectral and prosodic features for computer-assisted language learning systems
(Elsevier Science, 2015-02)
We present a system for detection of lexical stress in English words spoken by English learners. This system was designed to be part of the EduSpeak® computer-assisted language learning (CALL) software. The system uses ...
Automatic detection of gaze and body orientation in elementary school classrooms
(Frontiers Media, 2021)
Detecting the direction of the gaze and orientation of the body of both teacher and students is essential to estimate who is paying attention to whom. It also provides vital clues for understanding their unconscious, ...
Instantaneous Phase Threshold for Reflector Detection in Ultrasonic Images
(Institute of Electrical and Electronics Engineers (IEEE), 2014-07-01)
A method for reflector detection, based on the instantaneous phase of the aperture data for ultrasonic images, is proposed. The instantaneous phase (IP) image is obtained by replacing the amplitude information by the ...

Desempenho de adultos jovens normais em dois testes de resolução temporal
(Pró-Fono Produtos Especializados para Fonoaudiologia Ltda., 2008-03-01)
BACKGROUND: temporal auditory processing is defined as the perception of sound or of sound alteration within a restricted time interval and is considered a fundamental ability for the auditory perception of verbal and non ...
The ghost of stochastic resonance: an introductory review
(Taylor & Francis Ltd, 2012-01)
Nonlinear systems driven by noise and periodic forces with more than one frequency exhibit the phenomenon of Ghost Stochastic Resonance (GSR) found in a wide and disparate variety of fields ranging from biology to geophysics. ...
Polarity-Dependent Transcranial Direct Current Stimulation Effects on Central Auditory Processing
(PUBLIC LIBRARY SCIENCE, 2011)
Given the polarity dependent effects of transcranial direct current stimulation (tDCS) in facilitating or inhibiting neuronal processing, and tDCS effects on pitch perception, we tested the effects of tDCS on temporal ...
Spatial-temporally resolved high-frequency surface acoustic waves on silicon investigated by femtosecond spectroscopy
(American Institute Of Physics, 2012-06)
Various types of surface acoustic waves are generated by femtosecond pulses on bulk silicon with aluminium stripe transducers. Rayleigh and leaky longitudinal surface acoustic wave modes are detected in the time domain for ...
