    • Emergence of linguistic laws in human voice 

      González Torre, Iván; Luque Serrano, Bartolo; Lacasa, Lucas; Luque, Jordi; Hernández Fernández, Antonio (Macmillan Publishers, 2017-03-08)
      Article
      Accés obert
      Linguistic laws constitute one of the quantitative cornerstones of modern cognitive sciences and have been routinely investigated in written corpora, or in the equivalent transcription of oral corpora. This means that ...
    • Improving i-Vector and PLDA based speaker clustering with long-term features 

      Woubie, Abraham; Luque, Jordi; Hernando Pericás, Francisco Javier (International Speech Communication Association (ISCA), 2016)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      i-vector modeling techniques have been successfully used for speaker clustering task recently. In this work, we propose the extraction of i-vectors from short-and long-term speech features, and the fusion of their PLDA ...
    • Jitter and Shimmer measurements for speaker diarization 

      Zewoudie, Abraham Woubie; Luque, Jordi; Hernando Pericás, Francisco Javier (2014)
      Text en actes de congrés
      Accés obert
      Jitter and shimmer voice quality features have been successfully used to characterize speaker voice traits and detect voice pathologies. Jitter and shimmer measure variations in the fundamental frequency and amplitude ...
    • Multimodal identification and localization of users in a smart environment 

      Salah, Albert Ali; Morros Rubió, Josep Ramon; Luque, Jordi; Segura Perales, Carlos; Hernando Pericás, Francisco Javier; Ambekar, Onkar; Schouten, Ben; Pauwels, Eric (2008-09)
      Article
      Accés obert
      Detecting the location and identity of users is a first step in creating contextaware applications for technologically-endowed environments. We propose a system that makes use of motion detection, person tracking, face ...
    • Seeing and hearing egocentric actions: how much can we learn? 

      Cartas Ayala, Alejandro; Luque, Jordi; Radeva, Petia; Segura, Carlos; Dimiccoli, Mariella (2019)
      Text en actes de congrés
      Accés obert
      Our interaction with the world is an inherently multi-modal experience. However, the understanding of human-to-object interactions has historically been addressed focusing on a single modality. In particular, a limited ...
    • Short- and long-term speech features for hybrid HMM-i-vector based speaker diarization system 

      Zewoudie, Abraham Woubie; Luque, Jordi; Hernando Pericás, Francisco Javier (2016)
      Comunicació de congrés
      Accés obert
      i-vectors have been successfully applied over the last years in speaker recognition tasks. This work aims at assessing the suitability of i-vector modeling within the frame of speaker diarization task. In such context, a ...
    • Simultaneous speech detection with spatial features for speaker diarization 

      Zelenak, Martin; Segura Perales, Carlos; Luque, Jordi; Hernando Pericás, Francisco Javier (2012-02)
      Article
      Accés restringit per política de l'editorial
      Simultaneous speech poses a challenging problem for conventional speaker diarization systems. In meeting data, a substantial amount of missed speech error is due to speaker overlaps, since usually only one speaker label ...
    • The L2F - UPC Speaker Recognition System for NIST SRE 2010 

      Abad, Alberto; Luque, Jordi; Trancoso, Isabel; Hernando Pericás, Francisco Javier (2011)
      Comunicació de congrés
      Accés obert
      This document describes the joint submission of the INESC-ID’s Spoken Language Systems Laboratory (L 2 F) and the TALP Research Center from the Technical University of Catalonia (UPC) to the 2010 NIST Speaker Recognition ...
    • The use of long-term features for GMM- and i-vector-based speaker diarization systems 

      Zewoudie, Abraham Woubie; Luque, Jordi; Hernando Pericás, Francisco Javier (2018-09-26)
      Article
      Accés obert
      Several factors contribute to the performance of speaker diarization systems. For instance, the appropriate selection of speech features is one of the key aspects that affect speaker diarization systems. The other factors ...
    • Using voice-quality measurements with prosodic and spectral features for speaker diarization 

      Zewoudie, Abraham Woubie; Luque, Jordi; Hernando Pericás, Francisco Javier (International Speech Communication Association (ISCA), 2015)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Jitter and shimmer voice-quality measurements have been successfully used to detect voice pathologies and classify different speaking styles. In this paper, we investigate the usefulness of jitter and shimmer voice ...
