- Cheongjae Lee, Alexander I. Rudnicky, G. G. Lee. 2010. Let's Buy Books: Finding eBooks using voice search. Abstract: We describe Let's Buy Books, a dialog system that helps users search for eBook titles. In this paper we compare different vector space approaches to voice search and find that a hybrid approach using a weighted sub-space model smoothed with a general model provides the best performance over different conditions and evaluated using both synthetic queries and queries collected from users through questionnaires.
