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) ...
SAAM: sistema de apoio a aprendizagem musical
(Universidade Tecnológica Federal do ParanáCuritibaBrasilBacharelado em Engenharia de ComputaçãoUTFPR, 2020-06-19)
One of the biggest problems in musical learning is the lack of feedback when the student is practicing at home. Another problem is the instrument tuning. The instrument should always be tuned for good practice. The Musical ...
Automatic recognition of accessible pedestrian signals
(2018)
Accessible pedestrian signals (APS) enhance accessibility in streets around the world. Recent attempts to extend the use of APS to people with visual and audible impairments have emerged from the area of audio signal ...
Aspectos comportamentais e eletrofisiológicos da percepção de alturas sonoras: um estudo sobre o ouvido absoluto
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM NEUROCIÊNCIAS, 2017-02-23)
In humans, the processing of sound information allowed the appearance of speech and music.
The pitch - which allows the melody of a song and prosody in spoken discourse - is one of
these attributes. Pitch perception is ...
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, ...
The use of instantaneous phase for improving sparse arrays images
(Ieee, 2013-01-01)
Sparse arrays have pitch larger than half-wavelength (lambda/2) and there is a reduced number of elements in comparison with a full-populated array. Consequently, there is a reduction in cost, data acquisition and processing. ...
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 ...
Detection of damage in structural waveguides using high frequency waves
(Universidade Estadual Paulista (Unesp), 2015-04-28)
Wave propagation research for Structural Health Monitoring (SHM) has been increasing recently. It allows the detection of damage at its early stages of development. This dissertation describes a theoretical study of wave ...
