An efficient browsing system for multi-media meeting recordings

摘要

We have developed Marc , a system for browsing multi-media recordings of small-party meetings. In this system, meetings are recorded by an input device consisting of an omni-directional camera and a microphone array. By applying audio signal processing and automatic speech recognition to the recordings, speakers are automatically identified and the keywords in their speech are detected. Using the obtained information as tags for speech events, a topic of interest can easily be searched by users.
