Abstract

The Ritel system aims to provide open-domain question answering to casual users by means of a telephone dialogue. This implies some unique challenges, such as very fast overall performance and large-vocabulary speech recognition. Speech QA is an error-prone process, but errors or problems that occur may be resolved with help of user feedback, as part of a natural dialogue. This paper reports on a pilot study conducted with the latest version of Ritel, which includes search term confirmation and improved follow-up question handling, as well as various improvements on the other system components. We collected a small dialogue corpus with the new system, which we use to evaluate and discuss it.
