This paper describes our approach to the estimation of confidence in the words generated by a speech recognition system. We describe the models and the features employed for confidence estimation. In addition we discuss the characteristics of an information -theoretic metric for assessing the performance of the confidence measure. We provide a simple application of confidence measures in which we rank the performance of speakers.
