Abstract(in English) We have investigated characteristic factors of voice and gesture of persuasive speaker for development the voice interaction agent of the education systems. We analyzed motion videos of 35 speakers, who make speech for a large audience at the large conference rooms. The subjects rated on a five-point scale of persuasive levels of the speakers' voice and gesture, and the speakers were divided into persuasive and unpersuasive groups. Then the speakers' impressions were rated by the subjects using 10 assessment words of voice and 12 assessment words of gesture. Factor analysis was performed for the impression rating data. As a result, we have found the characteristic factors of the voice were clear and comfort factors, and the clear factor of the persuasive speakers was larger than that of the unpersuasive speakers. And the characteristic factors of gesture were active and affinity factors, and the both factors of persuasive speaker were larger than the unpersuasive speakers.
