    In this work we present our entry for the Voice Conversion Challenge 2016, denoting new features to previous work on GMM-based voice conversion. We incorporate frequency warping and pitch transposition strategies to perform ...
  • Chung, Seong Taek; Lozano Solsona, Angel; Huang, Howard C.; Sutivong, Arak; Cioffi, John M. (Hindawi, 2004)
    This paper presents an extension of the vertical Bell Laboratories Layered Space-Time (V-BLAST) architecture in which the closed-loop multiple-input multiple-output (MIMO) capacity can be approached with conventional scalar ...
  • Barbieri, Francesco; Ballesteros, Miguel; Saggion, Horacio (ACL (Association for Computational Linguistics), 2017)
    Emojis are ideograms which are naturally combined with plain text to visually complement or condense the meaning of a message. Despite being widely used in social media, their underlying semantics have received little ...
  • Albó, Laia; Hernández Leo, Davinia; Oliver Riera, Miquel (2016)
    Most MOOCs offer open learning opportunities at Higher Education (HE) level./nHowever, it is still unclear how HE students are taking this type of course. This/nstudy focuses on the profile of HE students participating in ...
  • Lozano Solsona, Angel; Jindal, Nihar (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    The purpose of this paper is to examine some of the models commonly used to represent/nfading as well as the information-theoretic metrics most commonly used to evaluate performance/nover those models. We raise the question ...
  • Vessel, Edward A; Starr, Gabrielle; Rubin, Nava (Frontiers Media, 2013)
    In a task of rating images of artworks in an fMRI scanner, regions in the medial prefrontal cortex that are known to be part of the default mode network (DMN) were positively activated on the highest-rated trials. This is ...
  • Geffner, Héctor (IOS Press, 2014)
    Artificial Intelligence is a brain child of Alan Turing and his universal programmable computer. During the 1960s and 1970s, AI researchers used computers for exploring intuitions about intelligence and for writing programs ...
  • Srinivasamurthy, Ajay; Holzapfel, Andre; Ganguli, Kaustuv Kanti; Serra, Xavier (Frontiers, 2017)
    This article provides insights into aspects of tempo and rhythmic elaboration in Hindustani music, based on a study of a large corpus of recorded performances. Typical tempo developments and stress patterns within a ...
  • Serrà Julià, Joan; Koduri, Gopala Krishna; Miron, Marius; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2011)
    The issue of tuning in Indian classical music has been, historically,/na matter of theoretical debate. In this paper, we/nstudy its contemporary practice in sung performances of Carnatic/nand Hindustani music following an ...
  • Giménez Mínguez, Paula; Bijnens, Bart; Bernardino Perez, Gabriel; Lluch Alvarez, Èric; Soveral, Iris; Gómez, Olga; García Cañadilla, Patricia, 1985- (Springer, 2017)
    Introduction: Aortic coarctation is one of the most difficult cardiac defects to diagnose before birth, and it accounts for 8% of congenital heart diseases. Antenatal diagnosis is crucial for early treatment of the neonate ...
  • Rudenick, Paula A.; Bijnens, Bart; Segers, Patrick F.; García-Dorado, David; Evangelista, Arturo (Public Library of Science (PLoS), 2015)
    Descending aortic dissection (DAD) is associated with high morbidity and mortality rates. Aortic wall stiffness is a variable often altered in DAD patients and potentially involved in long-term outcome. However, its relevance ...
  • Biglieri, Ezio (National Institute of Information and Communications Technology (NICT), 2008)
    We examine a multiple-access communication system in which multiuser detection is performed without knowledge of the number of active interferers. Using a statistical-physics approach, we compute the single-user channel ...
  • Schmitz, Judith, 1984-; Díaz Menéndez, Begoña, 1979-; Sebastián Gallés, Núria (Taylor & Francis (Routledge), 2016)
    Previous studies showed that manipulating the speech production system influenced speech perception. This influence was mediated by task difficulty, listening conditions, and attention. In the present study we investigated ...
  • Öktem, Alp; Farrús, Mireia; Wanner, Leo (Springer, 2017)
    Until very recently, the generation of punctuation marks for automatic speech recognition (ASR) output has been mostly done by looking at the syntactic structure of the recognized utterances. Prosodic cues such as breaks, ...
  • Attrapadung, Nuttapong; Herranz, Javier; Laguillaumie, Fabien; Libert, Benoît; De Panafieu, Elie; Ràfols, Carla (Elsevier, 2012)
    Attribute-based encryption (ABE), as introduced by Sahai and Waters, allows for fine- grained access control on encrypted data. In its key-policy flavor (the dual ciphertext-policy scenario proceeds the other way around), ...
  • Font Corbera, Frederic; Serrà Julià, Joan; Serra, Xavier (Audio Engineering Society, 2014)
    Methods for automatic sound and music classification are of great value when trying to organise the large amounts of unstructured, user-contributed audio content uploaded to online sharing platforms. Currently, most of ...
