A statistical corpus-based synthesis strategy has been developed
for fundamental frequency contours (*F*_{0}) of Spanish sentences.
Input text is assumed to be made of a sequence of intonation
groups, each one containing one or more stress groups. The
stress group is taken as the basic prosodic unit at acoustic level.
For every kind of acoustic unit, we get a set of statistical distributions
for the parameters of a Bézier function that generates
the *F*_{0} contour of the unit. This distributions are obtained directly
from the corpus and two different models are annalyzed.
In one of them, linguistic knowledge forces the grouping of
stress groups, while in the other an unsupervised clustering is
carried out. Comparison of the results of both methods show
the relative importance of different prosodic features found in
real data.
