Figures

Image of FIG. 1.
FIG. 1.

Artificial thick palate (mid-sagittal view) (image taken from Baum and MacFarland, 1997).

Image of FIG. 2.
FIG. 2.

Tongue sensor placement (body = tongue body; blade = tongue blade; tip = tongue tip; leftLat = tongue lateral left; rightLat = tongue lateral right).

Image of FIG. 3.
FIG. 3.

Screen illustrating the marking of tongue blade minimum velocity for a fricative and a stop.

Image of FIG. 4.
FIG. 4.

Average values and SD of center of gravity and SD for the four consonants. Data are shown for the no sensor condition (0OFFOFF) and the no palate condition before practice (1OFFPRE).

Image of FIG. 5.
FIG. 5.

Average values and SD of within-speaker normalized values of center of gravity and SD for the four consonants. Data are shown for the perturbed condition (thin palate preperturbation-2NTHINPRE, thick palate preperturbation 3NTHICKPRE, thick palate post-perturbation 4NTHICKPOST, thin palate post-perturbation 5NTHINPOST).

Image of FIG. 6.
FIG. 6.

Average values and SD of center of gravity and SD for the four consonants in the normal condition pre-perturbation (1OFFPRE) and post-perturbation (6OFFPOST).

Image of FIG. 7.
FIG. 7.

Average values and SD of within-speaker normalized values of articulatory parameters for the four consonants. Data are shown for the perturbed condition (thin palate pre-perturbation 2NTHINPRE, thick palate pre-perturbation 3NTHICKPRE, thick palate post-perturbation 4NTHICKPOST, thin palate post-perturbation 5NTHINPOST).

Tables

Generic image for table
TABLE I.

Results of repeated-measure ANOVAs and paired t-test conducted on the two acoustic parameters: Center of gravity (CofG) and standard deviation (SD) (*p ≤ 0.05, **p ≤ 0.01).

Generic image for table
TABLE II.

Results of repeated-measure ANOVAs and paired t-test conducted on the articulatory parameters: tongue blade sensor (bladex, bladez), tongue body sensor (bodyx, bodyz), interlabial distance (interlab), jaw sensor (jaw), tongue left lateral sensor (leftlat), tongue tip sensor (tipx, tipz), and protrusion (ulx) (*p ≤ 0.05, ** p ≤ 0.01).
