    The proposed paper introduces a novel method for range estimation of acoustic sources, both cetaceans and industrial sources, in deep sea environments using supervised learning with neural networks in the contex of a single ...
  • A neural network approach for automatic detection of acoustic alarms 

    Peiró Lilja, Alexandre; Raboshchuk, Ganna; Nadeu Camprubí, Climent (Scitepress, 2017)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    Acoustic alarms generated by biomedical equipment are relevant sounds in the noisy Neonatal Intensive Care Unit (NICU) environment both because of their high frequency of occurrence and their possible negative effects on ...
  • Non parametric coding of speech by means of a MLP with hints 

    Hernández, G; Monte Moreno, Enrique; Mariño Acebal, José Bernardo (Springer, 1997)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper presents a non parametric compression system which makes use of the fact that a MLP has an internal representation of the data in the hidden layer. The system that we present makes a compression by using 4 or 8 ...
  • LSTM neural network-based speaker segmentation using acoustic and language modelling 

    India Massana, Miquel Àngel; Rodríguez Fonollosa, José Adrián; Hernando Pericás, Francisco Javier (International Speech Communication Association (ISCA), 2017)
    Comunicació de congrés
    Accés obert
    This paper presents a new speaker change detection system based on Long Short-Term Memory (LSTM) neural networks using acoustic data and linguistic content. Language modelling is combined with two different ...

    The rapid growth of multimedia databases and the human interest in their peers make indices representing the location and identity of people in audio-visual documents essential for searching archives. Person discovery ...
  • Spanish dialects: phonetic transcription 

    Moreno Bilbao, M. Asunción; Mariño Acebal, José Bernardo (International Speech Communication Association (ISCA), 1998)
    Text en actes de congrés
    Accés obert
    It is well known that canonical Spanish, the dialectal variant `central' of Spain, so called Castilian, can be transcribed by rules. This paper deals with the automatic grapheme to phoneme transcription rules in several ...
  • A billingual texto-to-speech system in spanish and catalan 

    Bonafonte Cávez, Antonio; Esquerra Llucià, Ignasi; Febrer Godayol, Albert; Vallverdú Bayés, Sisco (Editors: G. Kokkinakis, N. Fakotakis, E. Dermatas; Editorial: WCL, University of Patras, Grece, 1997)
