    • Analysis and synthesis of vibrato in lyric singers 

      Arroabarren Alemán, Ixone Upna; Carlosena García, Alfonso Upna (2002)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this paper two aspects of the vibrato signal characterisation are presented. First, an analysis method, which breaks down the musical signal into its different partials, and decomposes them into two separate ...
    • Effect of the glottal source and the vocal tract on the partials amplitude of vibrato in male voices 

      Arroabarren Alemán, Ixone Upna; Carlosena García, Alfonso Upna (Acoustical Society of America, 2006)   Artículo / Artikulua  OpenAccess
      In this paper the production of vocal vibrato is investigated. The most relevant features of the acoustical vibrato signal, frequency and amplitude variations of the partials, will be related to the voice production ...
    • Glottal spectrum based inverse filtering 

      Arroabarren Alemán, Ixone Upna; Carlosena García, Alfonso Upna (ISCA, 2003)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this paper a new inverse filtering technique for the time-domain estimation of the glottal excitation is presented. This approach uses the DAP modeling for the vocal tract characterization, and a spectral model for the ...
    • Modelling of vibrato production 

      Arroabarren Alemán, Ixone Upna; Carlosena García, Alfonso Upna (2004)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this paper, a novel Non-Interactive Source-Filter model for singing voice, incorporating vibrato, is proposed. In this way the periodic frequency variation, peculiar to vibrato is included in a simplified signal model ...
    • Unified analysis of glottal source spectrum 

      Arroabarren Alemán, Ixone Upna; Zivanovic, Miroslav Upna; Carlosena García, Alfonso Upna (ISCA, 2003)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The spectral study of the glottal excitation has traditionally been based on a single time-domain mathematical model of the signal, and the spectral dependence on its time domain parameters. Opposite to this approach, ...
    • Vibrato in singing voice: the link between source-filter and sinusoidal models 

      Carlosena García, Alfonso Upna; Arroabarren Alemán, Ixone Upna (Springer Open, 2004)   Artículo / Artikulua  OpenAccess
      The application of inverse filtering techniques for high-quality singing voice analysis/synthesis is discussed. In the context of source-filter models, inverse filtering provides a noninvasive method to extract the voice ...
