Comparing KEC Recordings with Resynthesized EMA Data

Authors: Konstantin Sering, Fabian Tomaschek

Abstract:

Comparing simulated articulatory movements to their real counterparts is critical in establishing some trust in the findings produced by a simulator and the simulator’s generalizability. Point-wise and global measures are compared in this study on a dataset of human EMA recordings and resynthesised simulated EMA data. Most measures show comparable sensitivity to the hypothesized structure of dissimilarity along different groups of EMA trajectories but fail to fulfill metrical properties. A measure based on the Jensen-Shannon-distance (JSD) seem to show good sensitivity and fulfills the triangle inequality and is therefore suggested to be used in evaluating resynthesis models.
