在本文中，我们研究用户适应系统的词汇和句法选择的上下文中部署的让我们去！对话系统我们表明，在部署的对话系统与真实的用户，在实验室实验中，用户适应系统的词汇和句法的选择。我们还表明，该系统的词汇和句法的选择，以及随之而来的用户适应，可以有一个任务相关的概念识别的影响。这意味着，即使在灵活的输入对话系统中，系统提示公式也可以用于引导用户产生有助于任务成功的话语。
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 systems with real users, as in laboratory experiments, users adapt to the system's lexical and syntactic choices. We also show that the system's lexical and syntactic choices, and consequent 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 conducive to task success.
