Performance of speech recognition systems strongly degrades in the presence of background noise, like the driving noise inside a car. In contrast to existing works, we aim to …
J Bouvrie, T Ezzat, T Poggio - 2008 IEEE International …, 2008 - ieeexplore.ieee.org
Drawing on recent progress in auditory neuroscience, we present a novel speech feature analysis technique based on localized spectro-temporal cepstral analysis of speech. We …
Over the past two decades several hierarchical learning models have been developed and applied to a diverse range of practical tasks with much success. Little is known, however, as …
This paper proposes methods for combining cepstral and acoustic waveform representations for a front-end of support vector machine (SVM)-based speech recognition …
HA Chang, JR Glass - 2007 IEEE Workshop on Automatic …, 2007 - ieeexplore.ieee.org
In this paper we present a hierarchical large-margin Gaussian mixture modeling framework and evaluate it on the task of phonetic classification. A two-stage hierarchical classifier is …
Although operator-valued kernels have recently received increasing interest in various machine learning and functional data analysis problems such as multi-task learning or …
Classification of speech phonemes is challenging, especially under noisy environments, and hence traditional speech recognition systems do not perform well in the presence of …
L Golipour, DD O'Shaughnessy - INTERSPEECH, 2010 - isca-archive.org
In this paper we propose a k-NN/SASH phoneme classification algorithm that competes favourably with state-ofthe-art methods. We apply a similarity search algorithm (SASH) that …
