  • Model-based processing for acoustic scene analysis 

    Nadeu Camprubí, Climent; Chakraborty, Rupayan; Wolf, Martin (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report

    The analysis of acoustic scenes requires several functionalities, being perhaps recognition (speech, speaker, other acoustic events) and spatial localization the two most relevant ones. For a reduced invasiveness, ...
  • Stay-Away, protecting sensitive applications from performance interference 

    Rameshan, Navaneeth; Navarro Moldes, Leandro; Monte Moreno, Enrique; Vlassov, Vladimir (Association for Computing Machinery (ACM), 2014)
    Conference report

    While co-locating virtual machines improves utilization in resource shared environments, the resulting performance interference between VMs is difficult to model or predict. QoS sensitive applications can suffer from ...
  • Jitter and Shimmer measurements for speaker diarization 

    Zewoudie, Abraham Woubie; Luque, Jordi; Hernando Pericás, Francisco Javier (2014)
    Conference report
    Open Access
    Jitter and shimmer voice quality features have been successfully used to characterize speaker voice traits and detect voice pathologies. Jitter and shimmer measure variations in the fundamental frequency and amplitude ...
  • Deep belief networks for i-vector based speaker recognition 

    Ghahabi Esfahani, Omid; Hernando Pericás, Francisco Javier (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    The use of Deep Belief Networks (DBNs) is proposed in this paper to model discriminatively target and impostor i-vectors in a speaker verification task. The authors propose to adapt the network parameters of each speaker ...
  • The strategic impact of META-NET on the regional, national and international level 

    Rehm, Georg; Uszkoreit, Hans; Ananiadou, Sophia; Bel, Nuria; Moreno Bilbao, M. Asunción (2014)
    Conference lecture
    Open Access
    This article provides an overview of the dissemination work carried out in META-NET from 2010 until early 2014; we describe its impact on the regional, national and international level, mainly with regard to politics and ...
  • i-Vector modeling with deep belief networks for multi-session speaker recognition 

    Ghahabi Esfahani, Omid; Hernando Pericás, Francisco Javier (2014)
    Conference report
    Restricted access - publisher's policy
    In this paper we propose an impostor selection method for a Deep Belief Network (DBN) based system which models i-vectors in a multi-session speaker verification task. In the proposed method, instead of choosing a ...
  • The TALP-UPC phrase-based translation systems for WMT13: system combination with morphology generation, domain adaptation and corpus filtering 

    Formiga Fanals, Lluís; Ruiz Costa-Jussà, Marta; Mariño Acebal, José Bernardo; Rodríguez Fonollosa, José Adrián; Barrón Cedeño, Luis Alberto; Màrquez Villodre, Lluís (2013)
    Conference report

    This paper describes the TALP participation in the WMT13 evaluation campaign. Our participation is based on the combination of several statistical machine translation systems: based on standard hrasebased Moses systems. ...
  • Bandwidth extension of narrowband speech 

    Expósito Pérez, Miquel; Salavedra Molí, Josep (Universidad Politécnica de Valencia, 2014)
    Conference report
    Open Access
    Recently, 4G mobile phone systems have been designed to process wideband speech signals whose sampling frequency is 16 kHz. However, most part of mobile and classical phone network, and current 3G mobile phones, still ...
  • Sound-model-based acoustic source localization using distributed microphone arrays 

    Chakraborty, Rupayan; Nadeu Camprubí, Climent (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    Acoustic source localization and sound recognition are common acoustic scene analysis tasks that are usually considered separately. In this paper, a new source localization technique is proposed that works jointly with an ...
  • Audiovisual event detection towards scene understanding 

    Canton Ferrer, Cristian; Butko, Taras; Segura, C.; Giró Nieto, Xavier; Nadeu Camprubí, Climent; Hernando Pericás, Francisco Javier; Casas Pla, Josep Ramon (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Conference report
    Restricted access - publisher's policy
    Acoustic events produced in meeting environments may contain useful information for perceptually aware interfaces and multimodal behavior analysis. In this paper, a system to detect and recognize these events from a ...
