Fifth International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2007)
This work presents a procedure for the estimation
of a two-mass vocal fold model starting from a time-varying
target ²ow signal. The model is speci±ed by a large number of
physical parameters, computed as functions of four articulatory
parameters (three laryngeal muscle activations and subglottal
pressure). Flow waveforms synthesized by the model
are characterized by means of a set of typical voice source
quanti±cation acoustic parameters. Given a sequences of target
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.
