ABSTRACT
Navigation systems are widely used yet little is understood about how aspects of the interaction impact our assessment of these systems. Our work focuses on the speech output, exploring how accent and system errors affect our credibility judgements. Findings from a small-scale pilot study show that destination errors significantly affect user trust and competence assessments of a navigation system. People also rate navigation systems using speech output with a similar accent to their own as more trustworthy than a system using a different accent, irrespective of destination errors made. Future work looks to increase the scale of the study and add further conditions to explore the role of user nationality, accent and the geographical location being navigated on system credibility.
