The relationship between acoustic habitat, hearing and tonal vocalizations in the Antillean manatee (Trichechus manatus manatus, Linnaeus, 1758)
(2015-09)
The Antillean manatee (Trichechus manatus manatus) is an endangered marine mammal that inhabits the Caribbean Sea and riverine systems in Central America. Their acoustic behavior is relevant for individual identification, ...
SWIPE: A Sawtooth Waveform Inspired Pitch Estimator for Speech and Music
(2011-10-11)
A Sawtooth Waveform Inspired Pitch Estimator (SWIPE) has been developed for processing speech and music. SWIPE is shown to outperform existing algorithms on several publicly available speech/musical-instruments databases ...
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 ...
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 ...
