VEU - Grup de Tractament de la Parla

 

L'àmbit de recerca del grup 'VEU' és el tractament de la parla. Investiguem tecnologies que permeten l'extracció d'informació que la veu conté: reconeixement del que es diu, l'idioma o el dialecte, característiques del parlant -qui és, la seva edat, el sexe, l'estat emocional-, la direcció del so. També treballem en la caracterització general de l'àudio, per determinar quan hi ha veu i quan hi ha altres esdeveniments acústics com música o sorolls diversos. Les tecnologies de la parla possibiliten generar veu -síntesis de veu- o modificar les seves

    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 ...

  • Automatic detection of alarm sounds in a noisy hospital environment using model and non-model based approaches 

    Raboshchuk, Ganna; Gómez Quintana, Sergi; Peiró Lilja, Alexandre; Nadeu Camprubí, Climent (2017-11-12)
    Report de recerca
    Accés obert
    In the noisy acoustic environment of a Neonatal Intensive Care Unit (NICU) there is a variety of alarms, which are frequently triggered by the biomedical equipment. In this paper different approaches for automatic detection ...

  • Joint model-based recognition and localization of overlapped acoustic events using a set of distributed small microphone arrays 

    Chakraborty, Rupayan; Nadeu Camprubí, Climent (2017-12-19)
    Report de recerca
    Accés obert
    In the analysis of acoustic scenes, often the occurring sounds have to be detected in time, recognized, and localized in space. Usually, each of these tasks is done separately. In this paper, a model-based approach to ...
