Experiments in confidence scoring using Spanish CallHome data
Proceedings of the 1998 IEEE International Conference on Acoustics, Speech and Signal Processing, ICASSP '98 (Cat. No.98CH36181)
We present results relevant to tasks involved in the confidence scoring of output from a continuous speech recognition system, including the search for predictor variables and model selection. We introduce the DET curve characteristic (DCC) score, which we use along with the normalized cross entropy (NCE) score, to perform the model and predictor variable evaluation. We also show results from experiments that suggest how the NCE and DCC scores vary with recognizer performance.doi:10.1109/icassp.1998.674404 dblp:conf/icassp/Vaver98 fatcat:djeem4dljvhabm6kaco5norfkq
