在 LE-3 ARISE（欧洲自动铁路信息系统）项目的背景下，我们一直在开发一个对话系统，用于通过语音获取铁路旅行信息。该系统提供法国主要城际交通的时刻表信息，以及模拟票价和预订、折扣和服务。目标是通过非常开放的对话结构获得高对话成功率，用户可以在任何时间点自由提出任何问题或提供任何信息。为了提高这种开放对话策略的性能，我们利用调用者措辞（如果可能）进行隐式确认，并在对话进展不顺利时更改为更受约束的对话级别。除了我们自己的评估之外，原型系统还接受我们法国铁路合作伙伴定期进行的用户评估。
In the context of the LE-3 ARISE (Automatic Railway Information Systems for Europe) project we have been developing a dialog system for vocal access to rail travel information. The system provides schedule information for the main French intercity connections, as well as, simulated fares and reservations, reductions and services. The goal is to obtain high dialog success rates with a very open dialog structure, where the user is free to ask any question or to provide any information at any point in time. In order to improve the performance with such an open dialog strategy, we make use of implicit confirmation using the callers wording (when possible), and change to a more constrained dialog level, when the dialog is not going well. In addition to own assessment, the prototype system undergoes periodic user evaluations carried out by the our partners at the French Railways.
