| Abstract(in English) | In many speech recognition systems, the speech features are based on MFCC. Exactly speaking, the 1st-12th MFCC, the 0th-12th ΔMFCC and the 0th-12th ΔΔMFCC are used into these systems. Under noisy condition, the spectral subtraction (SS) and the cepstrum mean subtraction (CMS) are widely used and the 0th MFCC is not used into these methods since the recognition accuracy is declined. As the new noise robust speech feature extraction, i.e., the running spectrum filtering (RSF) and the dynamic range adjustment (DRA) have been developed. In this report, the role of the 0th MFCC is investigated into RSF and DRA. The evaluation on this speech feature is shown in some experiments. |
