<br/>   abstract  = {Previous work has identified a considerable role of the facilitator of creativity
workshops; in this study, we investigate to what extent the observable differences
between facilitators can be attributed to facilitators&#039; speaking style. Specifically,
we study the effects of pitch range. That pitch range may have an influence on listeners&#039;
creativity can be expected from the fact that it is associated with higher engagement.
In order to eliminate effects of speaker personality, we use a robotic facilitator. In an
online questionnaire, videos of a robot provided the participants with the necessary
instructions on a creativity task, where the pre-synthesized speech of the robot was
manipulated globally concerning pitch range. Dependent variables were the originality,
fluency, flexibility and degree of elaboration of participants&#039; ideas, as well as their
subjective ratings of the robot facilitator. The results show significantly higher facilitator
ratings and creativity-task performances in connection with the robot that used
the larger pitch range. We discuss our results in terms practical applications and further
relevant voice features.},
