State of the art language recognition systems usually add a backend prior to the linear fusion of the subsystems scores. The backend plays a dual role. When the set of languages for which models have been trained does not match the set of target languages , the backend maps the available scores to the space of target languages. On the other hand, the(More)
This paper briefly describes the system presented by the Working Group on Software Technologies (GTTS) 1 of the University of the Basque Country (UPV/EHU) to the Spoken Web Search task at MediaEval 2012. The GTTS system apply state-of-the-art phone decoders to search for approximate matchings of the N-best decodings of a spoken query in the phone lattice of(More)
In this paper, we describe the " Spoken Web Search " Task, which is being held as part of the 2013 MediaEval campaign. The purpose of this task is to perform audio search in multiple languages and acoustic conditions, with very few resources being available for each individual language. This year the data contains audio from nine different languages and is(More)
Most common approaches to phonotactic language recognition deal with several independent phone decod-ings. These decodings are processed and scored in a fully uncoupled way, their time alignment (and the information that may be extracted from it) being completely lost. Recently, a new approach to phonotactic language recognition has been presented [1],(More)
This paper evaluates the performance of the twelve primary systems submitted to the evaluation on speaker verification in the context of a mobile environment using the MOBIO database. The mobile environment provides a challenging and realistic test-bed for current state-of-the-art speaker verification techniques. Results in terms of equal error rate (EER),(More)
The Albayzin 2010 Language Recognition Evaluation (LRE), carried out from June to October 2010, was the second effort made by the Spanish/Portuguese community for benchmarking language recognition technology. As the Albayzin 2008 LRE, it was coordinated by the Software Technology Working Group of the University of the Basque Country, with the support of the(More)
In the framework of a contract with the Basque Parliament for subtitling the videos of bilingual plenary sessions, which basically consisted of aligning very long (around 3 hours long) audio tracks with syntactically correct but acoustically inaccurate text transcriptions (since all the disfluencies, mistakes, etc. were edited), a very simple and efficient(More)
In this paper, we describe the " Query by Example Search on Speech Task " (QUESST, formerly SWS, " Spoken Web Search "), held as part of the MediaEval 2014 evaluation campaign. As in previous years, the proposed task requires performing language-independent audio search in a low resource scenario. This year, the task has been designed to get as close as(More)
