FIG. 7

Vowel recognition performance using the surface paradigm. The data are presented as a 3D wire-mesh surface (no interpolation), with height showing mean percent correct. The GPR and SER combinations used in the experiment are shown by the circles on the 2D projection plane lying below the 3D surface. Recognition threshold (50%, d′=1.0 in 5AFC) is shown by the thick black contour on the 2D plane. For other details cf. Fig. 6.
