Abstract Conversational interfaces that interact with humans need to continuously establish, maintain and repair common ground in task-oriented dialogues. Uncertainty, repairs acknowledgements are expressed user behaviour the continuous efforts of conversational partners mutual understanding. Users change their when interacting systems different forms embodiment, which affects abilities these observe users’ recurrent social signals. Additionally, intellectually biased towards activity facing anthropomorphic agents or presented subtle cues. Two studies this paper examining how a referential communication task wizarded embodiment. In study 1 (N = 30), we test whether respond same way agents, embodiment behaviour. 2 44), replicate but introduce failures disrupting process grounding. Findings indicate it is not always favourable for be anthropomorphised communicate non-verbal cues, as human grounding behaviours manipulated.
