The ambient spotlight: queryless desktop search from meeting speech

Abstract

It has recently become possible to record any small meeting using a laptop equipped with a plug-and-play USB microphone array. We show the potential for such recordings in a personal aid that allows project managers to record their meetings and, when reviewing them afterwards through a standard calendar interface, to find relevant documents on their computer. This interface is intended to supplement or replace the textual searches that managers typically perform. The prototype, which relies on meeting speech recognition and topic segmentation, formulates and runs desktop search queries in order to present its results
