Fifth International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2007)
This paper presents predictions of the
consequences of tongue surgery on speech
production. For this purpose, a 3D finite element
model of the tongue is used that represents this
articulator as a deformable structure in which
tongue muscles anatomy is realistically described.
Two examples of tongue surgery, which are
common in the treatment of cancers of the oral
cavity, are modelled, namely a hemiglossectomy
and a large resection of the mouth floor. In both
cases, three kinds of possible reconstruction are
simulated, assuming flaps with different stiffness.
Predictions are computed for the cardinal vowels
/i, a, u/ in the absence of any compensatory
strategy, i.e. with the same motor commands as the
one associated with the production of these vowels
in non-pathological conditions. The estimated
vocal tract area functions and the corresponding
formants are compared to the ones obtained under
