This work aims at gaining an insight into the mean and variance normalization technique (MVN), which is commonly used to increase the robustness of speech recognition features. Several versions of MVN are empirically investigated, and the factors affecting their performance are considered. The reported experimental work with real-world speech data (Speecon)(More)
To assess the effect of diet enrichment with L-arginine or supplementation at high doses on physiological adaptation during exercise, 9 athletes followed 3 different diets, each over 3 consecutive days, with a wash-out period of 4 d between training sessions: control diet (CD), 5.5 +/- 0.3 g/d of L-arginine; Diet 1 (rich in L-arginine food), 9.0 +/- 1.1 g/d(More)
Recently, the advantages of the spectral parameters obtained by frequency filtering (FF) of the logarithmic filter-bank energies (logFBEs) have been reported. These parameters, which are frequency derivatives of the logFBEs, lie in the frequency domain, and have shown good recognition performance with respect to the conventional mel-frequency cepstral(More)
The aim of the study was to determine the effects of an antioxidant supplementation, which includes coenzyme Q10, on plasma and neutrophil oxidative stress and the antioxidant response after a soccer match. Nineteen voluntary male pre-professional footballers were randomly and double-blinded treated with either a multivitamin and mineral supplement (n = 8)(More)
In this paper we deal with the robustness problem in speech recognition, using a Spanish subset of the recently collected SPEECON database, and focusing on the front-end side of the recognizer. Cross-microphone and cross-environment recognition tests are presented using both read and spontaneous continuous speech utterances. Our semi-continuous sub-word HMM(More)

PURPOSE To determine abnormalities in tear osmolarity (TO), tear function, and impression cytology in patients with pterygium and to assess the relationship between the variables. METHODS Thirty eyes from 30 patients with primary nasal pterygium and 30 eyes from 30 volunteers without ocular pathologies or dry eye symptoms were enrolled in the present(More)
METHODS: This is a descriptive, longitudinal, prospective, non-randomised study of 32 eyes in 32 patients with pterygium, and operated using the limbal-conjunctival autograft technique in our hospital in the year 2011. Standardised photographs were taken and corneal topography was performed preoperatively, one month, and 3 months after the intervention. The(More)
PURPOSE To analyze the effects of tear hyperosmolarity on conjunctival cells in mild to moderate dry eye. METHODS Sixty-eight subjects (35 females and 33 males, mean age 43, S.D. 20.3, range 18-87 years) with symptoms of dry eye were enrolled in the study. Patients with severe dry eye or any other condition that induces ocular inflammation were excluded.(More)
Optical coherence tomography (OCT) has become a very useful tool to study in vivo different ocular structures and to improve differential diagnosis and management of many ocular pathologies. This study aims to identify pterygium alterations that trigger characteristic OCT images, and analyze if this pattern correctly demarcates lesion boundary. Thirty-two(More)
