[en] Conversational agents (CAs) that deliver proactive interventions can benefit users by reducing their cognitive workload and improving performance. However, little is known regarding how such interventions would impact perception of CA’s appropriateness in voice-only, decision-making tasks. We conducted a within-subjects experiment (N=30) to evaluate the effect of CA’s feedback delivery strategy at three levels (no feedback, unsolicited, and solicited feedback) in an interactive food ordering scenario. We discovered that unsolicited feedback was perceived to be more appropriate than solicited feedback. Our results provide preliminary insights regarding the impact of proactive feedback on CA perception in decision-making tasks.
