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 for singing voice production.
The inclusion of vibrato will further allow to relate
two distinct signal models for the voice: The Non Interactive
Source-Filter and the Sinusoidal Models. In this way, the
Instantaneous Amplitude and Instantaneous Frequency of
the harmonics, which are intrinsically Sinusoidal Model
parameters, will be related to the glottal source and vocal
tract response, typical of the Source-Filter model.
Thanks to the proposed model, the most relevant acoustic
features of vibrato will be related to the voice production
mechanisms.
