Comparison of Several Compensation Techniques for Robust Speaker Verification

Summary

It is well known that the performance of speaker recognition systems degrade rapidly as the mismatch between the training and test conditions increases. Thus, for example, in real-world telephone-based speaker recognition systems, both, additive and convolutional noise influence the error rate considerably. In this paper, different techniques which make a speaker verification system more robust against noise are described and compared. Some of these techniques have already been successfully applied in Robust Speech Recognition, and our preliminary results show that they are also very encouraging for Robust Speaker Verification.
