    abstract = "Given the conflicting expectations users have for how a dialog agent should sound and behave, there is no one-size-fits-all option for dialog system design. Therefore, adaptation is critical to ensure successful and enjoyable interactions. However, it is not yet clear what the effects of behavioral (what the agent says) vs. linguistic adaptation (how the agent says this) are in terms of dialog success and user perception. In this work, we implement three different types of task-oriented dialog agents which can each vary their level of formality. We evaluate subjective and objective metrics of dialog success as well as user perceptions through a user study, comparing the collected data to that of (CITATION), where users interacted with the same three types of agents without linguistic adaptation. From this, we draw insights into which subjective and objective aspects of success and user perception are influenced by each type of adaptation. We additionally all code, user surveys, and dialog interaction logs."
