In this paper, we examine user adaptation to the system’s lexical and syntactic choices in the context of the deployed Let’s Go! dialog system. We show that in deployed dialog sys- tems with real users, as in laboratory experi- ments, users adapt to the system’s lexical and syntactic choices. We also show that the sys- tem’s lexical and syntactic choices, and con- sequent user adaptation, can have an impact on recognition of task-related concepts. This means that system prompt formulation, even in flexible input dialog systems, can be used to guide users into producing utterances con- ducive to task success.
