24.2.4 Intonation
For intonation there are number of simple options without requiring training data. For this example we will simply
use a hat pattern on all stressed syllables in content words and on single syllable content words. (i.e. Simple) Thus
we need an accent prediction CART tree.
(set! spanish_accent_cart_tree
'
((R:SylStructure.parent.gpos is content)
((stress is 1)
((Accented))
((position_type is single)
((Accented))
((NONE))))
((NONE))))
We also need to specify the pitch range of our speaker. We will be using a male Spanish diphone database of the
follow range
(set! spanish_el_int_simple_params
'((f0_mean 120) (f0_std 30)))

24.2.5 Duration
We will use the trick mentioned above for duration prediction. Using the zscore CART tree method, we will actually
use it to predict factors rather than zscores.
The tree predicts longer durations in stressed syllables and in clause initial and clause final syllables.
