Résumé: In this article, we address to what extent the proverb "the sound makes the music" also applies to human-robot interaction, and whether robots could profit from using speech characteristics similar to those used by charismatic speakers like Steve Jobs. In three empirical studies, we investigate the effects of using Steve Jobs' and Mark Zuckerberg's speech characteristics during the generation of robot speech on the robot's per-suasiveness and its impressionistic evaluation. The three studies address different human-robot interaction situations, which range from online questionnaires to real-time interactions with a large service robot, yet all involve both behavioral measures and users' assessments. The results clearly show that robots can profit from using charismatic speech.
