Abstract: This work presents a procedure for the estimation
of a two-mass vocal fold model starting from a time-varying
target flow signal. The model is specified by a large number of
physical parameters, computed as functions of four articula-
tory parameters (three laryngeal muscle activations and sub-
glottal pressure). Flow waveforms synthesized by the model
are characterized by means of a set of typical voice source
quantification acoustic parameters. Given a sequences of tar-
get acoustic parameters, dynamic programming techniques
and interpolation based on Radial Basis Function Networks
are used to derive sequences of articulatory parameters that
lead to resynthesis of the target signal.
Keywords: Voice source, Low-dimensional models, Estimation,
