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.},
