Allen Animated agents are becoming increasingly frequent in research and applications in speech science. An important challenge is to evaluate the effectiveness of the agent in terms of the intelligibility of its visible speech. In three experiments we extend and test the Sumby and Pollack 1954 metric to allow the comparison of an agent relative to a standard or reference and also propose a new metric based on the fuzzy logical model of perception FLMP to describe the benefit provided by a synthetic animated face relative to the benefit provided by a natural face. A valid metric would allow direct comparisons accross different experiments and would give measures of the benfit of a synthetic animated face relative to a natural face or indeed any two conditions and how this benefit varies as a function of the type of synthetic face the test items e.g. syllables versus sentences different individuals and applications.

INTRODUCTION It is not surprising that face-to-face communication is more effective than situations involving just the voice. One reason is that the face improves intelligibility particularly when the auditory signal is degraded by the presence of .
