Abstract:This paper explores the effects of a voice assistant’s (VA) speech quality (synthetic, natural human voice) and gender (female, male) on the user’s trust in the assistant (measured by integrity, competence, benevolence) as well as in the automated vehicle (AV) (measured by system transparency, technical competence, situation management), in which the VA operates. First, trust in the VA was expected to positively affect trust in the AV. Second, assistants with a natural human voice were expected to score best on all the given constructs. Third, a female voice was expected to score better on all constructs, except for competence and technical competence, where a male voice was seen superior. The proposed hypotheses have been tested with an experimental 2x2 study design, incorporating four videos with manipulated VAs, followed by a survey (N=100). It was identified that trust in the VA causes trust in the AV, further stimulating the need to explore the design of trustful VAs. Accordingly, organizations can improve the adoption of AVs, and finally decrease human-caused road fatalities. However, no main effects were found for speech quality or gender. Lastly, the study contributes to future work in the same domain, by giving recommendations based on the findings and identified shortcomings.
