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.
