We propose an improvement to the centisecond TLHMM model
(Meziane, 1999) applied to the sound duration. Indeed, the
distribution of the sound duration depends on the speaking rate.
An adaptation in a post-processing step is needed. This
adaptation is studied by proposing a model of the speaking rate
based on average syllabic duration. The experiments elaborated on
a set of BDSONS show the interest of this approach.
This work is a continuation of those by Meziane (1999) and
