FIG. 18.
Transformed coefficient and formant trajectories of vowel sequences for male speakers JW12 and JW61 relative to an area function model. The coefficient trajectories are transformed versions of those in Figs. 11c and 12c (via Eqns. 4–7). The formant trajectories were calculated from area functions generated by Eqn. 9. Further description of the figure is the same as Fig. 17.
