The Effects of Anthropomorphised Virtual Conversational Assistants on Consumer Engagement and Trust During Service Encounters

Drawing on social exchange and anthropomorphism theory, this research examines the role of virtual conversational assistants (VCA) as frontline employees. Specifically, we investigate the effects of AI-derived features, such as anthropomorphism, in building Human-Machine relationships. Drawing on a qualitative interpretivist approach, 31 semi-structured interviews were conducted with global users of Siri, Alexa and Google Assistant. Our findings suggest anthropomorphism is an important factor in understanding the development of trust within Human-Machine interactions. More specifically, the effects of a humanised voice, interactive communication capability and cognitive features evoke a sense of social presence that may positively or negatively impact user trust. We propose that the interplay between a user’s perceptions of the bright and dark sides of interacting with an AI-empowered anthropomorphised machine determines categories of trust and subsequent customer engagement behaviours with this embedded form of organisational frontline.
