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