This study compares four automatic methods for estimating Fujisaki-model parameters. Since interpolation and smoothing are necessary prerequisites for all approaches their fitting accuracies are also compared with that of a novel stylisation method. A hand-corrected set of results from one of the methods which was created on linguistic grounds served as a second benchmark. Although the four methods yield comparable results with respect to their total errors, they show different error distributions. The manually corrected version provided a poorer approximation of the F0 contours than the automatic one.
