L'àmbit tecnològic del centre és el processament automàtic del llenguatge, tant en forma oral com escrita, amb l'objectiu d'ajudar a superar les barreres lingüístiques, facilitant la interacció entre persones, entre persones i dispositius, i l'accessibilitat a la informació multilingüe.
Tecnologies de la llengua són aquelles relacionades amb la creació, la gestió i la utilització de tecnologia i de recursos lingüístics (diccionaris, gramàtiques, etc.) per construir sistemes informàtics capaços de comprendre, interpretar i generar les diverses maneres que tenim els humans per comunicar-nos.
En el pla científic, aquesta activitat es basa en disciplines com ara l'aprenentatge automàtic, el processament de la senyal, la lingüística de corpus, l’enginyeria lingüística o el processament del llenguatge natural escrit o parlat. En el pla quotidià, s’inclou en un ventall ampli d’aplicacions cada cop més habituals: cercadors intel·ligents, assistents virtuals, sistemes automàtics d’atenció.

  • Filtering the time sequences of spectral parameters for speech recognition 

    Nadeu Camprubí, Climent; Paches, Pau; Biing-Hwang, Juang (1997-09)
    Article
    Accés restringit per política de l'editorial
    In automatic speech recognition, the signal is usually represented by a set of time sequences of spectral parameters (TSSPs) that model the temporal evolution of the spectral envelope frame-to-frame. Those sequences are ...
  • Speech recognition in a noisy car environment based on LP of the one-sided autocorrelation sequence and robust similarity measuring techniques 

    Hernando Pericás, Francisco Javier; Nadeu Camprubí, Climent; Mariño Acebal, José Bernardo (1997-02)
    Article
    Accés restringit per política de l'editorial
    The performance of the existing speech recognition systems degrades rapidly in the presence of background noise. A novel representation of the speech signal, which is based on Linear Prediction of the One-Sided Autocorrelation ...
  • Adaptive blind system identification using weighted cumulant slices 

    Vidal Manzano, José; Rodríguez Fonollosa, José Adrián (1996-03)
    Article
    Accés restringit per política de l'editorial
    Many linear methods have been proposed in the literature to blindly estimate the ARMA parameters of a time series using HOS. Nevertheless, they are mainly off-line and not much has been done in the adaptive case. The method ...
  • Automatic speech recognition with deep neural networks for impaired speech 

    España-i-Bonet, Cristina; Rodríguez Fonollosa, José Adrián (2016-11-23)
    Article
    Accés restringit per política de l'editorial
    Automatic Speech Recognition has reached almost human performance in some controlled scenarios. However, recognition of impaired speech is a difficult task for two main reasons: data is (i) scarce and (ii) heterogeneous. ...
  • 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 ...
  • Deep neural networks for i-vector language identification of short utterances in cars 

    Ghahabi Esfahani, Omid; Bonafonte Cávez, Antonio; Hernando Pericás, Francisco Javier; Moreno Bilbao, M. Asunción (International Speech Communication Association (ISCA), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This 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, ...
  • Sample cumulants of stationary processes: asymptotic results 

    Rodríguez Fonollosa, José Adrián (1995-04)
    Article
    Accés obert
    In this paper, we present the formulas of the covariances of the second-, third-, and fourth-order sample cumulants of stationary processes. These expressions are then used to obtain the analytic performance of FIR system ...

    Article
    Accés obert
    The Self-Organizing Map (SOM) is a neural network algorithm that has the special property ofcreating spatially organized tepresetüatioes of various features of input signals. The resulting maps resemble realneural structures ...
