Comparison of MFCC and PLP parameterizations in the speaker independent continuous speech recognition task

Popis výsledku v původním jazyce

This paper is a contribution to the discussion about an optimal parameterization of speech signals in speech recognition systems. Our experiments deal with a telephone-based speaker independent continuous speech recognition task. In tests the MFCC and PLP parameterizations were tested and compared. The benefit of an adjustment of the filters used in the MFCC and PLP parameterizations to the critical bandwidth of hearing was explored. In addition, the impact of the number of filters and enumerated parameters to the recognition accuracy was tested. As results showed the MFCC parameterization is less sensitive to satisfying the theory of the critical bandwidth of hearing than the PLP. Experiments also proved that 5 PLP-cepstral (including derived 5 delta+ 5 delta-delta) coefficients do not afford the best results as could be deduced from recent work.
