Abstract

There has been a long-standing methodology for evaluating work in speech recognition (SR), but until recently no community-wide methodology existed for either natural language (NL) researchers or speech understanding (SU) researchers for evaluating the systems they developed.Recently considerable progress has been made by a number of groups involved in the DARPA Spoken Language Systems (SLS) program to agree on a methodology for comparative evaluation of SLS systems, and that methodology is being used in practice for the first time.This paper gives an overview of the process that was followed in creating a meaningful evaluation mechanism, describes the current mechanism, and presents some directions for future development.
