Impact of duration on F1/F2 formant values of oral vowels: an automatic analysis of large broadcast news corpora in French and German.

Abstract : Formant values of oral vowels are automatically measured in
a total of 50000 segments from four hours of journalistic
broadcast speech in French and German. After automatic
segmentation using the LIMSI speech alignment system,
formant values are automatically extracted using PRAAT.
Vowels with unlikely formant values are discarded (4%). The
measured values are exposed with respect to segment duration
and language identity. The gap between the measured mean
Fi values and reference Fi values is inversely proportional to
vowel duration: a tendency to reduction for vowels of short
duration clearly emerges for both languages. These results are
briefly discussed in terms of centralisation and coarticulation.
