Analyses formantiques automatiques en français : périphéralité des voyelles orales en fonction de la position prosodique.
Résumé
The aim of the present study is to highlight peripherality
of French vowels in two prosodic positions: (i) word-final
syllables (as compared to word-initial syllables), and (ii)
in the vicinity of (before and after) pauses. The LIMSI
speech alignment system is used [1] and formant values
of oral vowels are automatically measured in a total of
25000 segments from two hours of journalistic broadcast
speech in French. A tendency to reduction for all vowels
(in terms of the shrinking of the vocalic triangle formed
by F1 and F2 values) of short duration was clearly
observed in a former study (Gendrot & Adda-Decker [2]).
We show that at some extent, a similar relationship holds
for vowels in both word-final and word-initial syllables.
