SGER: Let's Go Lab

口语对话系统的进步依赖于一些策略系统变化如何影响真实的用户行为的研究。由于对话系统的任何变化都会引起用户所说内容的变化，因此非实时的、预先录制的对话语料库可能无法衡量这种变化。这项可行性研究，让我们去实验室，探讨使用一个共同的对话平台的替代可能性。Let's Go系统正在作为对话研究的概念验证语音研究社区资源提供。Let's Go为阿勒格尼县港务局接听电话，每天从晚上7点到早上6点向平均60个来电者提供日程安排信息。研究人员提出了一项研究，并与Let's Go实验室团队合作，根据需要修改基础系统，进行离线测试，最后“上线”，与真实的用户进行大量对话，测试他们的假设。该项目将探讨小的变化（取代一个系统发声）和大的（改变对话管理架构）是否可行。Let's Go团队还在研究如何通过重复使用过去的模块、改进“上线”标准以及培训研究人员参与准备工作来降低每项新研究的启动成本。如果这个项目成功，它将为一个新的、强大的社区资源铺平道路，在这个社区资源中，可以在一个共同的平台上比较结果，可以测试统计上显著数量的真实的用户，新的研究人员可以很容易地进入这个领域。

Advances in spoken dialogue systems rely on studies of how some strategic system change affects real user behavior. Since any change to a dialogue system provokes a change in what users say, it is probable that non-live, pre-recorded dialog corpora cannot measure what that change will be. This feasibility study, Let's Go Lab, explores the alternative possibility of using a common dialogue platform. The Let's Go system is being made available as a proof-of-concept speech research community resource for dialogue studies. Let's Go answers the phone for the Port Authority of Allegheny County to give scheduling information from 7pm to 6am every day to an average of 60 callers.Researchers propose a study and work with the Let's Go Lab team to modify the base system as needed, run offline tests, and finally "go live", testing their hypotheses on significant quantities of dialogues with real users. The project will explore whether both minor changes (replacing one system utterance) and major ones (changing the dialogue management architecture) are feasible. The Let's Go team is also examining how to lessen startup costs for each new study by reusing past modules, refining "go live" criteria, and training researchers to participate in the preparatory work. If this project is successful, it will pave the way for a new, powerful community resource where results can be compared on a common platform, statistically significant numbers of real users can be tested and new researchers can enter the field easily.
