Abstract

This paper describes a novel approach to the problems of topic and speaker identification that makes use of large vocabulary continuous speech recognition. A theoretical framework for dealing with these problems in a symmetric way is provided, and some empirical results on topic and speaker identification are presented that have been obtained on the extensive Switchboard corpus of telephone conversations collected by Texas Instruments.
