  • Dzhambazov, Georgi Bogomilov; Yang, Yile; Caro Repetto, Rafael; Serra, Xavier (International Workshop on Folk Music Analysis, 2016)
    In this study we propose how to modify a standard approach for text-to-speech alignment to apply in the case of alignment of lyrics and singing voice. We model phoneme durations by means of a duration-explicit hidden Markov ...
  • Costa-jussà, Marta R.; Farrús, Mireia; Mariño Acebal, José B.; Fonollosa, José A Rodriguez (European Language Resources Association (ELRA), 2010)
    Machine translation systems can be classified into rule-based and corpus-based approaches, in terms of their core technology. Since both paradigms have largely been used during the last years, one of the aims in the research ...
  • Giraldo, Sergio; Ortega, Ariadna; Perez, Alfonso; Ramírez, Rafael; Waddell, George; Williamon, Aaron (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    The automatic assessment of music performance has become an area of special interest due to the increasing amount of technology-enhanced music learning systems. However, in most of these systems the assessment of the musical ...
  • Oramas, Sergio; Sordo, Mohamed; Serra, Xavier (Society for Interdisciplinary Musicology, 2014)
    Most of the current musicological knowledge is present in printed books and manuscripts. In the last years greats efforts have been done in order to digitize and make available these documents in form of Digital Libraries. ...
  • Farrús, Mireia; Costa-jussà, Marta R. (Athabasca University Press, 2013)
    Assessment in education allows for obtaining, organizing, and presenting information about how much and how well the student is learning. The current paper aims at analysing and discussing some of the most state-of-the-art ...
  • Farrús, Mireia; Costa-jussà, Marta R.; Cobo, Germán; García, David; Villarejo, Luis; Banchs, Rafael E (2010)
    The UOC is an online university where students follow an online continuous assessment system in order to successfully complete their studies. Due to the growing number of students, the task of marking their assessment tests ...
  • Öktem, Alp; Farrús, Mireia; Wanner, Leo (ACL (Association for Computational Linguistics), 2017)
    This paper presents a methodology to extract parallel speech corpora based on any language pair from dubbed movies, together with an application framework in which some corresponding prosodic parameters are extracted. ...
  • Lotinac, Damir; Segovia-Aguas, Javier; Jiménez, Sergio; Jonsson, Anders, 1973- (Association for the Advancement of Artificial Intelligence (AAAI), 2016)
    In many domains generalized plans can only/nbe computed if certain high-level state features,/ni.e. features that capture key concepts to accurately/ndistinguish between states and make good decisions,/nare available. In ...
  • Wang, Xingce; Liu, Yue; Wu, Zhongke; Mou, Xiao; Zhou, Mingquan; González Ballester, Miguel Ángel, 1973-; Zhang, Chong (2017)
    Identifcation of anatomical vessel branches is a prerequisite task for diagnosis, treatment and inter-subject comparison. We propose a novel graph labeling approach to anatomically label vascular structures of interest. ...
  • Igual, Laura; Preciozzi, Javier; Garrido, Luís; Almansa, Andrés; Caselles, Vicente; Rougé, Bernard (AIMS American Institute of Mathematical Sciences, 2007)
    In this work we propose a new automatic methodology for computing accurate digital elevation models (DEMs) in urban environments from low baseline stereo pairs that shall be available in the future from a new kind of earth ...
  • Dzhambazov, Georgi Bogomilov; Sentürk, Sertan; Serra, Xavier (Computer Engineering Department, Bogaziçi University, 2014)
    We apply a lyrics-to-audio alignment state-of-the-art approach to polyphonic pieces from classical Turkish repertoire. A phonetic recognizer is employed, whereby each phoneme is assigned a hidden Markov model (HMM). Initially ...
  • Demirel, Emir; Bozkurt, Baris; Serra, Xavier (2018)
    This work focuses on the automatic makam recognition task for Turkish Makam Music using chroma features. Chroma features are widely used for music identification and tonal recognition tasks such as key estimation or chord ...
  • Pragst, Louisa; Miehle, Juliana; Ultes, Stefan; Minker, Wolfgang (ACL (Association for Computational Linguistics), 2016)
    In task-oriented dialogues, there is often only one right answer the system can give. However, a lack of variation can seem repetitive and unnatural. Humans change the way they express something, e.g. by being more or less ...
  • Slizovskaia, Olga; Gómez Gutiérrez, Emilia, 1975-; Haro Ortega, Gloria (Zentrum für Mikrotonale Musik und Multimediale Komposition (ZM4), Hochschule für Musik und Theater Hamburg, 2016)
    The goal of this work is to incorporate the visual modality into a musical instrument recognition system. For that, we first evaluate state-of-the-art image recognition techniques in the context of music instrument ...
  • Lai, Catherine; Farrús, Mireia; Moore, Johanna D. (International Speech Communication Association (ISCA), 2016)
    As long-form spoken documents become more ubiquitous in everyday life, so does the need for automatic discourse segmentation in spoken language processing tasks. Although previous work has focused on broad topic segmentation, ...
  • Ramírez, Rafael,1966-; Maestre Gómez, Esteban; Pérez Carrillo, Alfonso Antonio, 1977-; Serra, Xavier (Taylor & Francis (Routledge), 2011)
    We present a machine learning approach to the problem of identifying performers from their interpretative styles. In particular, we investigate how violinists express their view of the musical content in audio recordings ...
  • Ramírez, Rafael,1966-; Maestre Gómez, Esteban; Serra, Xavier (Elsevier, 2010)
    We present a pattern recognition approach to the task of identifying performers from their interpretative styles. We investigate how professional musicians express their view of the musical content of musical pieces and ...
  • Farrús, Mireia; Wagner, Michael; Erro, Daniel; Hernando, Javier (Equinox Publishing, 2010)
    Voices can be deliberately disguised by means of human imitation or voice conversion. The question arises as to what extent they can be modified by using either of both methods. In the current paper, a set of speaker ...
