Parkinson's disease detection using modulation components in speech signals
(Institute of Electrical and Electronics Engineers Inc., 2019-06-06)
Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder after Alzheimer's. This disorder affects around 2% of elderly population. In Colombia, the prevalence of Parkinson's disease is around 172 ...
Alternative Measurement Instrument to Evaluate Executive Functions in Children of All Scholar Range
(Institute of Electrical and Electronics Engineers Inc, 2019-04-26)
Problems related to executive functions can be characterized as weaknesses in a set of mental skills that are key during the learning process. Child neuropsychologists are often asked to determine whether a child experiencing ...

Noise pollution can affect human health, according to research done by the World Health Organization (WHO), the European Union and the Spanish National Research Council, noise pollution can cause temporary deaf, hypertension ...
Fusion of bottleneck, spectral and modulation spectral features for improved speaker verification of neutral and whispered speech
(Elsevier B.V., 2018-07-27)
Speech based biometrics is becoming a preferred method of identity management amongst users and companies. Current state-of-the-art speaker verification (SV) systems, however, are known to be strongly dependent on the ...
Classification of nonverbal human produced audio events: A pilot study
(International Speech Communication Association, 2018-09-06)
The accurate classification of nonverbal human producedaudio events opens the door to numerous applications beyondhealth monitoring. Voluntary events, such as tongue clickingand teeth chattering, may lead to a novel way of ...
Fusion of auditory inspired amplitude modulation spectrum and cepstral features for whispered and normal speech speaker verification
(Academic Press, 2017-03-25)
Whispered speech is a natural speaking style that despite its reduced perceptibility, still contains relevant information regarding the intended message (i.e., intelligibility), as well as the speaker identity and gender. ...
Variants of mel-frequency cepstral coefficients for improved whispered speech speaker verification in mismatched conditions
(Institute of Electrical and Electronics Engineers Inc., 2017-10-26)
In this paper, automatic speaker verification using normal and whispered speech is explored. Typically, for speaker verification systems, varying vocal effort inputs during the testing stage significantly degrades system ...
