| Abstract | Robustness of phoneme recognition to additive noise is investigated for PLP and acoustic waveform representations of speech using support vector machines (SVMs) combined via error-correcting code methods. While recognition in the PLP domain attains superb accuracy on clean data, it is significantly affected by mismatch between training and testing noise levels. The classification in the high-dimensional acoustic waveform domain, on the other hand, is more robust to additive noise. Moreover, these classifiers perform best when trained on clean data. We also show that the simpler structure of the waveform representation allows one to improve performance using custom-designed kernel functions. |
