Graph edit distances between listeners and speakers.

In stimulus1 (left) and stimulus11 (right), the speaker S1 is placed in the origin and the speaker S2 (S3) at the corresponding distance along the x-axis while the coordinates of the listeners of both groups are shown in the distance plane. Concerning GED, both groups of listeners systematically appear closer to a “right” speaker (S2 in stimulus1, S1 in stimulus11) according to the listeners’ subjective ratings.
