4th International Conference on Spoken Language Processing
Philadelphia, PA, USA
We present a study of a speaker verification system for telephone data based on large-vocabulary speech recognition. After describing the recognition engine, we give details of the verification algorithm and draw comparisons with other systems. The system has been tested on a test set taken from the Switchboard corpus of conversational telephone speech, and we present results showing how performance varies with length of test utterance, and whether or not the training data has been transcribed. The dominant factor in performance appears to be channel or handset mismatch between training and testing data.
