Analysis of android robot lip-sync factors affecting communication

Abstract

In this paper, we analyze lip-sync factors affecting communication of android robots. We have generated eight mouth shapes for single vowels based on the Hangul vowel triangle chart. We assume that the mouth shape and lip-sync timing are important factors for communication with android robots. An experiment was conducted in a noisy environment during an exhibition. A total of 120 people were surveyed about how well they understood and why. Unlike the hypothesis, sound is found to be an important factor that affects human understanding. Because experimental results can be affected by noise and whether subjects have seen a robot or not, we will plan to conduct further experiments in a quiet environment after explaining android robots to subjects sufficiently.
