IA generativa i ChatGPT. Impacte en l’aprenentatge universitari
(2024)
Report de recerca
Accés obertEs presenten de forma planera els elements bàsics de la intel·ligència artificial (IA) generativa. Sobretot es descriuen els models de llenguatge de gran capacitat, que són la base d’eines com el xatbot ChatGPT. A continuació ... -
Improving detection of acoustic events using audiovisual data and feature level fusion
(2009)
Text en actes de congrés
Accés obertThe detection of the acoustic events (AEs) that are naturally produced in a meeting room may help to describe the human and social activity that takes place in it. When applied to spontaneous recordings, the detection ... -
Improving the robustness of the usual fbe-based asr front-end
(Mergablum, 2000)
Text en actes de congrés
Accés obertAll speech recognition systems require some form of signal representation that parametrically models the temporal evolution of the spectral envelope. Current parameterizations involve, either explicitly or implicitly, ... -
Inclusion of video information for detection of acoustic events using the fuzzy integral
(2008-01-01)
Article
Accés obertWhen applied to interactive seminars, the detection of acoustic events from only audio information shows a large amount of errors, which are mostly due to the temporal overlaps of sounds. Video signals may be a useful ... -
Incorporación de sensores acústicos en el control de regulación a un punto de un robot móvil
(2015)
Text en actes de congrés
Accés obertEste artículo describe el método Diferencia de Tiempo de Llegada (TDOA) para estimar la localización de fuentes acústicas en aplicaciones de regulación a un punto de un robot móvil. Al localizar fuentes acústicas con TDOA ... -
Incorporation of acoustic sensors in the regulation of a mobile robot
(2019-01-17)
Article
Accés obertThis article introduces the incorporation of acoustic sensors for the localization of a mobile robot. The robot is considered as a sound source and its position is located applying a Time Delay of Arrival (TDOA) method. ... -
Joint model-based recognition and localization of overlapped acoustic events using a set of distributed small microphone arrays
(2017-12-19)
Report de recerca
Accés obertIn the analysis of acoustic scenes, often the occurring sounds have to be detected in time, recognized, and localized in space. Usually, each of these tasks is done separately. In this paper, a model-based approach to ... -
Joint recognition and direction-of-arrival estimation of simultaneous meeting-room acoustic events
(2013)
Text en actes de congrés
Accés restringit per política de l'editorialAcoustic scene analysis usually requires several sub-systems working in parallel for carrying out the various required functionalities. Focusing to a more integrated approach, in this paper we present an attempt to jointly ... -
Les tecnologies de la parla: lloc de trobada, difícil però necessària, entre lingüística i tecnologia
(Publ. Univ. Jaume I, 2012)
Capítol de llibre
Accés obertLa recerca i el desenvolupament d'aplicacions en tecnologies de la parla han deixat força de banda els coneixements lingüístics. Les raons són diverses, com veurem, però la dificultat del treball conjunt de lingüistes i ... -
Linear prediction of the one-sided autocorrelation sequence for noisy speech recognition
(1997-01)
Article
Accés obertThe article presents a robust representation of speech based on AR modeling of the causal part of the autocorrelation sequence. In noisy speech recognition, this new representation achieves better results than several other ... -
Machine and deep learning approaches to localization and range estimation of underwater acoustic sources
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Comunicació de congrés
Accés restringit per política de l'editorialThis paper introduces ongoing experiments and early results for the underwater localization and range estimation of acoustic sources. Beyond classical results obtained for direction of arrival estimation, results concerning ... -
Maximum flatness spectral modeling
(1990-11)
Article
Accés obert -
Model-based processing for acoustic scene analysis
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialThe analysis of acoustic scenes requires several functionalities, being perhaps recognition (speech, speaker, other acoustic events) and spatial localization the two most relevant ones. For a reduced invasiveness, ... -
Modelling of the analytic spectrum for speech recognition
(European Speech Communication Association (ESCA), 1989)
Text en actes de congrés
Accés obertIn this paper, a new spectral representation is introduced and applied to speech recognition. As the widely used LPC autocorrelation technique, it arises from an optimization approach that starts from a set of M+ 1 ... -
Monolingual and bilingual spanish-catalan speech recognizers developed from SpeechDat databases
(C. Draxler, 2000)
Text en actes de congrés
Accés obertUnder the SpeechDat specifications, the Spanish member of SpeechDat consortium has recorded a Catalan database that includes one thousand speakers. This communication describes some experimental work that has been carried ... -
Multiple multilabeling applied to HMM-based noisy speech recognition
(1993)
Comunicació de congrés
Accés obertThe performance of existing speech recognition systems degrades rapidly in the presence of background noise when training and testing cannot be done under the same ambient conditions. The aim of this paper is to propose ... -
Multiple multilabeling to improve HMM-based speech recognition in noise
(1993)
Text en actes de congrés
Accés obertThe performance of existing speech recognition systems degrades rapidly in the presence of background noise when training and testing cannot be done under the same ambient conditions. The aim of this paper is to propose ... -
Multiple multilabelling applied to hmm-based noisy speech recognition
(CHINESE INSTITUTE OF ELECTRONICS, 1993)

On frequency averaging for spectral analysis in speech recognition
(Robert H. Mannel and Jordi Robert-Ribes, 1998)
Text en actes de congrés
Accés obertMany speech recognition systems use logarithmic filter-bank energies or a linear transformation of them to represent the speech signal. Usually, each of those energies is routinely computed as a weighted average of the ...
