A non-linear VAD for noisy environments

Solé-Casals, Jordi; Zaiats, Vladimir (Springer, 2010)

This paper deals with non-linear transformations for improving the performance of an entropy-based voice activity detector (VAD). The idea to use a non-linear transformation has already been applied in the field of ...
A Robust Multiple Feature Approach To Endpoint Detection In Car Environment Based On Advanced Classifiers

Comas, C.; Monte-Moreno, Enric; Solé-Casals, Jordi (Springer, 2005)

In this paper we propose an endpoint detection system based on the use of several features extracted from each speech frame, followed by a robust classifier (i.e Adaboost and Bagging of decision trees, and a multilayer ...
Application of the Mutual Information Minimization to speaker recognition / identification improvement

Solé-Casals, Jordi; Faundez-Zanuy, Marcos (Elsevier, 2006)

In this paper we propose the inversion of nonlinear distortions in order to improve the recognition rates of a speaker recognizer system. We study the effect of saturations on the test signals, trying to take into account ...
Detection of severe obstructive sleep apnea through voice analysis

Solé-Casals, Jordi; Munteanu, C.; Martin, O.C.; Barbé, F.; Queipo, C.; Amilibia, J.; Durán-Cantolla, J. (Elsevier, 2014)

tThis paper deals with the potential and limitations of using voice and speech processing to detect Obstruc-tive Sleep Apnea (OSA). An extensive body of voice features has been extracted from patients whopresent various ...
Maximum likelihood Linear Programming Data Fusion for Speaker Recognition

Monte-Moreno, Enric; Chetouani, Mohamed; Faundez-Zanuy, Marcos; Solé-Casals, Jordi (Elsevier, 2009)

Biometric system performance can be improved by means of data fusion. Several kinds of information can be fused in order to obtain a more accurate classification (identification or verification) of an input sample. In ...
Speaker recognition improvement using blind inversion of distortions

Faundez-Zanuy, Marcos; Solé-Casals, Jordi (2004)

In this paper we propose the inversion of nonlinear distortions in order to improve the recognition rates of a speaker recognizer system. We study the effect of saturations on the test signals, trying to take into ...
