abstract = {Oral vowels are mainly acoustically characterised by their two lowest
formants F1 and F2. It is well accepted that raising F1 is achieved by lowering the
jaw and the tongue whereas lowering F2 is achieved by moving the tongue backward
and protruding the lips. Conversely, it is well known that speakers differ in morphology
and articulatory strategy. This study intends therefore to characterise the interspeaker
articulatory variability associated with the variation of F1 and F2. For this
purpose, static midsagittal MRI from 21 speakers sustaining oral vowels were considered.
The vocal tract contours were manually segmented and aligned per speaker
and per articulation. The formants F1 and F2 were obtained by means of modelling.
The F1 and F2 articulatory components for each speaker were obtained by a linear
regression of the articulations on F1 and F2. Qualitative analyses showed a large inter-
speaker variability of the F1 and F2 components. Averaged F1 and F2 components
per sex revealed a similar strategy for males and females with subtle differences.
Quantitative analyses of the F1 and F2 componentsÂ’ variability did not reveal
clear organisation nor speaker cluster. Speakers tended to differ in the degree of use
of the jaw and of the larynx and in the region of the tongue used for the constriction.
These results suggest that the variations of the F1 and F2 components are not much
driven by morphological constraints and may rather be purely idiosyncratic. Further
analyses may include a larger number of speakers associated with deeper quantitative
analyses.},
