Modelling of vibrato production
(2004)
Contribución a congreso / Biltzarrerako ekarpena,
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 ...
Glottal spectrum based inverse filtering
(ISCA, 2003)
Contribución a congreso / Biltzarrerako ekarpena,
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 ...
Analysis and synthesis of vibrato in lyric singers
(2002)
Contribución a congreso / Biltzarrerako ekarpena,
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 ...
Unified analysis of glottal source spectrum
(ISCA, 2003)
Contribución a congreso / Biltzarrerako ekarpena,
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, ...
