Fig 2. Articulatory and acoustic data.

Fig 2

A–Positioning of the sensors on the lip corners (1 & 3), upper lip (2), lower lip (4), tongue tip (5), tongue dorsum (6), tongue back (7) and velum (8). The jaw sensor was glued at the base of the incisive (not visible in this image). B–Articulatory signals and corresponding audio signal for the sentence “Annie s’ennuie loin de mes parents” (“Annie gets bored away from my parents”). For each sensor, the horizontal caudo-rostral X and below the vertical ventro-dorsal Y coordinates projected in the midsagittal plane are plotted. Dashed lines show the phone segmentation obtained by forced-alignment. C–Acoustic features (25 mel-cepstrum coefficients—MEL) and corresponding segmented audio signal for the same sentence as in B.
