Assessing the robustness of recurrent neural networks to enhance the spectrum of reverberated speech
(2020)Implementing voice recognition systems and voice analysis in real-life contexts present important challenges, especially when signal recording/registering conditions are adverse. One of the conditions that produce signal ... -
Assessing the Total Cost of Ownership of Electric Vehicles in the Costa Rican Market
(2021)This article aims to describe how the electric vehicle market operates in Costa Rica. Different government policies have been defined in order to promote the insertion of electric vehicles. With the existing public charging ... -
Assessing two graph-based algorithms in a model-based testing platform for Java applications
(2020)Model-based testing (MBT) is an approach for auto- matically generating test cases from a model of the system under test. Existing MBT tools support the automation of this process at varying degrees. One such tool is ... -

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 ... -
Auto-Associative Initialization of LSTM Neural Networks for Fundamental Frequency Detection in Noisy Speech Signals
(2018)In this paper, we present a new approach for fundamental frequency detection in noisy speech, based on Long Short-term Memory Neural Networks (LSTM). Fundamental frequency is one of the most important parameters of human ... -
