CDHMM speaker recognition by means of frequency filtering of filter-bank energies
(1997)
Text en actes de congrés
Accés obertRecently, the set of spectral parameters of every speech frame that result from filtering the frequency sequence of mel-scaled filter-bank energies with a simple first-order high-pass FIR filter have proved to be an efficient ... -
Clustering initialization based on spatial information for speaker diarization of meetings
(2008)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper proposes an initialization for an agglomerative system applied to speaker diarization in the meeting environment. The initialization is based on a previous clustering of the temporal sequence generated by the ... -
Comparison of time & frequency filtering and cepstral-time matrix approaches in ASR
(1999)
Text en actes de congrés
Accés obertIn current speech recognition systems, speech is represented by a 2-D sequence of parameters that model the temporal evolution of the spectral envelope of speech. Linear transformation or filtering along both time and ... -

Deep belief networks for i-vector based speaker recognition
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialThe use of Deep Belief Networks (DBNs) is proposed in this paper to model discriminatively target and impostor i-vectors in a speaker verification task. The authors propose to adapt the network parameters of each speaker ... -
Deep learning backend for single and multisession i-vector speaker recognition
(2017-04-01)
Article
Accés obertThe lack of labeled background data makes a big performance gap between cosine and Probabilistic Linear Discriminant Analysis (PLDA) scoring baseline techniques for i-vectors in speaker recognition. Although there are some ... -
Deep neural networks for i-vector language identification of short utterances in cars
(International Speech Communication Association (ISCA), 2016)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper is focused on the application of the Language Identification (LID) technology for intelligent vehicles. We cope with short sentences or words spoken in moving cars in four languages: English, Spanish, German, ... -
Detection and handling of overlapping speech for speaker diarization
(2012)
Text en actes de congrés
Accés obertThis thesis concerns the detection of overlapping speech segments and its further application for the improvement of speaker diarization performance. We propose the use of three spatial cross-correlation-based parameters ... -

Discriminative weighting of dynamic feautres in continuous-density hidden Markov models for word recognition
(1995)
Text en actes de congrés
Accés obertSpeech dynamic features, which provide smoothed estimates of the derivatives of the spectral parameter trajectories in the current frame, are routinely used in current speech recognition systems in combination with short-term ... -
DNN speaker embeddings using autoencoder pre-training
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Comunicació de congrés
Accés restringit per política de l'editorialOver the last years, i-vectors have been the state-of-the-art approach in speaker recognition. Recent improvements in deep learning have increased the discriminative quality of i-vectors. However, deep learning architectures ... -
Double multi-head attention for speaker verification
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Text en actes de congrés
Accés obertMost state-of-the-art Deep Learning systems for text-independent speaker verification are based on speaker embedding extractors. These architectures are commonly composed of a feature extractor front-end together with a ... -
Dynamic time warping applied to detection of confusable word pairs in automatic speech recognition
(Escola Tècnica Superior d'Enginyers de Telecomunicació de Barcelona, 2005)
Article
Accés obertIn this paper we present a rnethod to predict if two words are likely to be confused by an Autornatic SpeechRecognition (ASR) systern. This method is based on the c1assical Dynamic Time Warping (DTW) technique. This ... -
End-to-end transparent user identification using touchscreen biometrics
(Universidad de Málaga, 2020)
Text en actes de congrés
Accés obertWe study the touchscreen data as behavioral biometrics. The goal was to create an end-to-end system that can transparently identify users using raw data from mobile devices. The touchscreen biometrics was researched only ... -
Esquema unificado de parametrización de la señal de voz en reconocimiento del habla
(Universidad de Valladolid, 1995)
Text en actes de congrés
Accés obertA correct choice of voice signal modeling methods is essential to obtain good results in automatic speech recognition. In this paper, we have proposed a unified view of the speech parametrization stage, in which conventional ... -
