A Battle of Voices: A Study of the Relationship between Driving Experience, Driving Style, and In-Vehicle Voice Assistant Character

Abstract

This study extends efforts to understand the interplay of contextual factors in the personalization of in-vehicle voice interfaces. In particular, an online study found that neither aggressiveness nor gender of voice assistants (VAs) would influence users' attitudes like trust, perceived usefulness and overall positive emotions, towards in-vehicle VAs. Our results contradict the similarity-attraction effect as the VAs' perceived aggressiveness, and drivers' preferences for aggressive driving styles did not correlate. In addition, the results showed that prior experiences might affect users' reliance and trust in VAs. This study also discovered relationships between users' attitudes to in-vehicle VAs and their age and driving experiences.
