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.

  • Time and frequency filtering for speech recognition with real noises 

    Macho, D; Nadeu Camprubí, Climent; Hernando Pericás, Francisco Javier (., 1999)
    Text en actes de congrés
    Accés obert
    very speech recognition system requires a signal representation that parametrically models the temporal evolution of the speech spectral envelope. Current parameterizations involve, either explicitly or implicitly, a set ...

  • Speaker recognition using frequency filtered spectral energies 

    Hernando Pericás, Francisco Javier (FONDAZIONE UGO BORDONI, 1999)
    Text en actes de congrés
    Accés obert
    The spectral parameters that result from filtering the frequency sequence of log mel-scaled filter-bank energies with a simple first or second order FIR filter have proved to be an efficient speech representation in ...
  • A second opinion approach for speech recognition verification 

    Hernández-Ábrego, G; Mariño Acebal, José Bernardo (M,I, Torres & A. Sanfeliu / AERFAI, 1999)
    Text en actes de congrés
    Accés obert
    In order to improve the reliability of speech recognition results, a verifying system, that takes profit of the information given from an alternative recognition step is proposed. The alternative results are considered as ...
  • Minimum confusibility training of context dependent demiphones 

    Nogueiras Rodríguez, Albino; Mariño Acebal, José Bernardo (G. Olaszy, G. Németh, K. Erdohegyi, 1999)
    Text en actes de congrés
    Accés obert
    During the last years two different approaches have been widely used in order to improve the acoustic modeling in continuous speech recognition systems: discriminative training algorithms and context dependent subword ...
  • Fuzzy reasoning in confidence evaluation of speech recognition 

    Hernández-Abrego, G; Mariño Acebal, José Bernardo (., 1999)
    Text en actes de congrés
    Accés obert
    Confidence measures represent a systematic way to express reliability of speech recognition results. A common approach to confidence measuring is to take profit of the information that several recognition-related features ...
  • Array joint detection for C/TDMA systems in UMTS environments 

    Antón Haro, Carles; Rodríguez Fonollosa, José Adrián; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 1998)
    Text en actes de congrés
    Accés obert
    Two array-based schemes for intracell and intercell interference suppression are proposed. In both cases, the spatial and temporal characteristics of the propagation are jointly exploited by placing a narrowband beamformer ...
  • On frequency averaging for spectral analysis in speech recognition 

    Nadeu Camprubí, Climent; Galindo, F; Padrell, J (Robert H. Mannel and Jordi Robert-Ribes, 1998)
    Text en actes de congrés
    Accés obert
    Many 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 ...
  • Automatic database acquisition software for ISDN PC cards and analogue boards 

    Rodríguez Fonollosa, José Adrián; Moreno Bilbao, M. Asunción (1998)
    Text en actes de congrés
    Accés obert
    This paper describes an application for automatic speechdatabases acquisition (ADA) developed by the authors in the framework of the EC Telematics Project SpeechDat II. The software is able to work with standard inexpensive ...
  • Phoneme recognition with statisticasl modeling of the prediction of the error of neural networks 

    Freitag, Fèlix; Monte Moreno, Enrique (Robert H. Mannel and Jordi Robert-Ribes, 1998)
    Text en actes de congrés
    Accés obert
    This paper presents a speech recognition system which incorporates predictive neural networks. The neural networks are used to predict observation vectors of speech. The prediction error vectors are modeled on the state ...
