This paper presents a simple approach to phonotactic dialect recognition which uses lattices of time-synchronous phone cooccurrences at the frame level. In previous works, we successfully applied cross-decoder phone co-occurrences to improve performance in language recognition experiments on the 2007 NIST LRE database. We call phone co-occurrence to the simultaneous (time-synchronous) presence ...

This paper presents the systems submitted by ATVS – Biometric Recognition Group at 2009 language recognition evaluation, organized by the National Institute of Standards and Technology of United States (NIST LRE’09). Apart from the huge size of the databases involved, two main factors turn the evaluation into a very difficult task. First, the number of languages to be recognized was the biggest...

Recently, i-vector based technology can provide good performance in language recognition (LRE). From the viewpoint of information theory, i-vectors derived from different acoustic features can contain more useful and complementary language information. In this paper, we propose an effective complementary combination for two kinds of i-vectors. One is derived from the commonly used short-term sp...

Currently, acoustic spoken language recognition (SLR) and phonotactic SLR systems are widely used language recognition systems. To achieve better performance, researchers combine multiple subsystems with the results often much better than a single SLR system. Phonotactic SLR subsystems may vary in the acoustic features vectors or include multiple language-specific phone recognizers and differen...

Interruptions in cerebral blood flow may lead to devastating neural outcomes. Magnetic resonance has a central role in diagnosing and monitoring these insufficiencies, as well as in understanding their underlying metabolic consequences. Magnetic resonance spectroscopy (MRS) in particular can probe ischemia via the signatures of endogenous metabolites including lactic acid (Lac), N-acetylasparta...

We present the work done by our group for the 2015 language recognition evaluation (LRE) organized by the National Institute of Standards and Technology (NIST). The focus of this evaluation was the development of language recognition systems for clusters of closely related languages using training data released by NIST. This training data contained a highly imbalanced sample from the languages ...

Human T cell leukemia virus type II (HTLV-II) has been isolated from a patient (Mo) with features of leukemic reticuloendotheliosis (LRE) and from a patient with acquired immunodeficiency syndrome (AIDS). We have obtained another isolate of HTLV-II from a patient (CM) with severe hemophilia A, pancytopenia, and a 14-year history of staphylococcal and candidal infections but no evidence of T cel...

To study the neural networks reorganization in pediatric epilepsy, a consortium of imaging centers was established to collect functional imaging data. Common paradigms and similar acquisition parameters were used. We studied 122 children (64 control and 58 LRE patients) across five sites using EPI BOLD fMRI and an auditory description decision task. After normalization to the MNI atlas, activat...

The Arabidopsis HY5 gene has been defined genetically as a positive regulator of photomorphogenesis and recently has been shown to encode a basic leucine zipper type of transcription factor. Here, we report that HY5 is constitutively nuclear localized and is involved in light regulation of transcriptional activity of the promoters containing the G-box, a well-characterized light-responsive elem...
