  • Adaptive prediction and bit-assignment in subband coding of speech 

    Mariño Acebal, José Bernardo; Martí Ros, Jaume (1985)
    Text en actes de congrés
    Accés obert
    The combination of time-domain harmonic scaling (TDHS) and sub-band coding (SBC) provides an encoding approach which allows 9.6 Kb/s speech encoding with good communication quality. Starting from this structure, this paper ...
  • ADN-classifier: automatically assigning denotation types to nominalizations

    Text en actes de congrés
    Accés obert
    This paper presents the ADN-Classifier, an Automatic classification system of Spanish Deverbal Nominalizations aimed at identifying its semantic denotation (i.e. event, result, underspecified, or lexicalized). The classifier ...
  • A fast one-pass-training feature selection technique for GMM-based acoustic event detection with audio-visual data 

    Butko, Taras; Nadeu Camprubí, Climent (2010)
    Text en actes de congrés
    Accés obert
    Acoustic event detection becomes a difficult task, even for a small number of events, in scenarios where events are produced rather spontaneously and often overlap in time. In this work, we aim to improve the detection ...
