A non-linear VAD for noisy environments
(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 ... -
A Robust Multiple Feature Approach To Endpoint Detection In Car Environment Based On Advanced Classifiers
(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, ... -
Application of the Mutual Information Minimization to speaker recognition / identification improvement
(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 ... -
Detection of severe obstructive sleep apnea through voice analysis
(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 ... -
Maximum likelihood Linear Programming Data Fusion for Speaker Recognition
(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 ... -
Speaker recognition improvement using blind inversion of distortions
(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 ...
