Do AI-powered digital assistants influence customer emotions, engagement and loyalty? An empirical investigation

PurposeDigital voice assistants (DVAs) are revolutionising consumers' interactions with technology and businesses. Whilst research on the adoption of these devices is rapidly expanding, few have explored post-adoption behaviour. To fill this gap, we investigate how functionality and human-like features shape customers' emotions, engagement and loyalty towards DVAs.Design/methodology/approachThe data were collected through a self-administered online survey from 509 DVA users. Structural equation modelling was employed for data analysis.FindingsThe results reveal that distinct human-like and functional factors of DVA independently explain customers' positive emotions and engagement with DVAs. Positive emotions and engagement significantly impact customer loyalty to DVAs. The study shows that localisation of DVAs has a significant positive moderating influence on the service experience-customer engagement relationship but a negative moderating influence on the anthropomorphism-customer engagement relationship.Originality/valueUnlike previous research, this study contributes to the literature by delving into post-adoption phenomena. It explains how DVAs' human-like and functional attributes drive customers' positive emotional responses, engagement and loyalty towards DVAs. The findings not only unveil new insights into the moderating role of localisation but also provide a crucial understanding regarding the boundary conditions of the influence of anthropomorphism and service experience on customer engagement.
