Robust speaker identification using auditory features and computational auditory scene analysis

The performance of speaker recognition systems drop significantly under noisy conditions. To improve robustness, we have recently proposed novel auditory features and a robust speaker recognition system using a front-end based on computational auditory scene analysis. In this paper, we further study the auditory features by exploring different feature dimensions and incorporating dynamic features. In addition, we evaluate the features and robust recognition in a speaker identification task in a number of noisy conditions. We find that one of the auditory features performs substantially better than a conventional speaker feature. Furthermore, our recognition system achieves significant performance improvements compared with an advanced front-end in a wide range of signal-to-noise conditions.
