  • Blaauw, Merlijn; Bonada, Jordi, 1973- (International Speech Communication Association (ISCA), 2017)
    We present a new model for singing synthesis based on a modified version of the WaveNet architecture. Instead of modeling raw waveform, we model features produced by a parametric vocoder that separates the influence of ...
  • Blaauw, Merlijn; Bonada, Jordi, 1973- (MDPI, 2017)
    We recently presented a new model for singing synthesis based on a modified version of the WaveNet architecture. Instead of modeling raw waveform, we model features produced by a parametric vocoder that separates the ...
  • Villavicencio, Fernando; Yamagishi, Junichi; Bonada, Jordi, 1973-; Espic, Felipe (International Speech Communication Association (ISCA), 2016)
    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 ...
  • Bonada, Jordi, 1973-; Lachlan, Robert; Blaauw, Merlijn (International Speech Communication Association (ISCA), 2016)
    This paper focuses on the synthesis of bird songs using Hidden Markov Models (HMM). This technique has been widely used for speech modeling and synthesis. However, features and contextual factors typically used for human ...
  • Gouyon, Fabien; Herrera Boyer, Perfecto; Gómez Gutiérrez, Emilia, 1975-; Cano, Pedro; Bonada, Jordi, 1973-; Loscos, Àlex; Amatriain, Xavier; Serra, Xavier (Logos Verlag, 2008)
    In this chapter, we provide an overview of state-of-the-art algorithms for the automatic description of music audio signals, both from a low-level perspective (focusing on signal characteristics) and a more musical perspective ...
  • Coleman, Graham Keith (Universitat Pompeu Fabra, 2016-02-05)
    Sampling, as a musical or synthesis technique, is a way to reuse recorded musical expressions. In this dissertation, several ways to expand sampling synthesis are explored, especially mosaicing synthesis, which imitates ...
  • Umbert Morist, Martí; Bonada, Jordi, 1973-; Goto, Masataka; Nakano, Tomoyasu; Sundberg, Johan (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    In the context of singing voice synthesis, expression control manipulates a set of voice features related to a particular emotion, style, or singer. Also known as performance modeling, it has been approached from different ...
  • Umbert Morist, Martí (Universitat Pompeu Fabra, 2016-01-29)
    This thesis focuses on the control of a singing voice synthesizer to achieve natural expression similar to a real singer. There are many features that should be controlled to achieve natural expression related to melody, ...
  • Bonada, Jordi, 1973-; Umbert Morist, Martí; Blaauw, Merlijn (International Speech Communication Association (ISCA), 2016)
    Sample and statistically based singing synthesizers typically require a large amount of data for automatically generating expressive synthetic performances. In this paper we present a singing synthesizer that using two ...
  • Stowell, Dan; Muševič, Sašo; Bonada, Jordi, 1973-; Plumbley, Mark D. (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Segregating an audio mixture containing multiple simultaneous bird sounds is a challenging task. However, birdsong often contains rapid pitch modulations, and these modulations carry information which may be of use in ...
  • Serra, Xavier; Bonada, Jordi, 1973-; Herrera Boyer, Perfecto; Loureiro, Ramon (International Computer Music Conference, 1997)
    Spectral based analysis/synthesis techniques offer powerful tools for the processing of sounds. They include many different approaches, each one with its own advantages and set of compromises. In the design of a general ...
  • Pérez Carrillo, Alfonso Antonio, 1977-; Bonada, Jordi, 1973-; Pätynen, Jukka; Välimäki, Vesa (National Research Council Canada Research Press, 2011)
    This work presents a method for measuring and computing violin-body directional frequency responses, which are used for violin sound synthesis. The approach is based on a frame-weighted deconvolution of excitation and ...
  • Amatriain, Xavier; Bonada, Jordi, 1973-; Serra, Xavier (International Conference on Digital Audio Effects, 1998)
    Since the MIDI 1.0 specification, well over 15 years ago, many have been the attempts to give a solution to all the limitations that soon became clear. None of these have had a happy ending, mainly due to commercial ...
  • Blaauw, Merlijn; Bonada, Jordi, 1973- (International Speech Communication Association (ISCA), 2016)
    Latent generative models can learn higher-level underlying factors from complex data in an unsupervised manner. Such models can be used in a wide range of speech processing applications, including synthesis, transformation ...
  • Muševič, Sašo (Universitat Pompeu Fabra, 2013-09-10)
    Muchos tipos de señales que encontramos a diario pertenecen a la categoría de sinusoides no estacionarias. Una gran parte de esas señales son sonidos que presentan una gran variedad de características: acústicos/electrónicos, ...
  • de Boer, Marteen; Bonada, Jordi, 1973-; Cano, Pedro; Loscos, Àlex; Serra, Xavier (International Computer Music Conference, 2000)
    This paper presents the implementation aspects of a real-time system for morphing two voices in the context of a karaoke application. It describes the software design and implementation under a PC platform and it discusses ...
  • Bonada, Jordi, 1973-; Celma Herrada, Òscar; Loscos, Àlex; Ortolà, Jaume; Serra, Xavier; Yoshioka, Yasuo; Kayama, Hiraku; Hisaminato, Yuji; Kenmochi, Hideki (International Computer Music Conference, 2001)
    This paper presents an approach to the modeling of the singing voice with a particular emphasis on the naturalness of the resulting synthetic voice. The underlying analysis/synthesis technique is based on the Spectral ...
  • Serra, Xavier; Bonada, Jordi, 1973- (International Conference on Digital Audio Effects, 1998)
    The basic Spectral Modeling Synthesis (SMS) technique models sounds as the sum of sinusoids plus a residual. Though this analysis/synthesis system has proved to be successful in transforming sounds, more powerful and ...
  • Bonada, Jordi, 1973-; Loscos, Àlex; Cano, Pedro; Serra, Xavier; Kenmochi, Hideki (Audio Engineering Society, 2001)
    In this paper we present two different approaches to the modeling of the singing voice. Each of these approaches has been thought to fit in the specific requirements of two applications. These are an automatic voice impersonator ...
  • Amatriain, Xavier; Bonada, Jordi, 1973-; Loscos, Àlex; Serra, Xavier (2001)
    When designing audio effects for music processing, we are always aiming at providing higherlevel representations that may somehow fill in the gap between the signal processing world and the end-user. Spectral models in ...
