| Abstract(in English) | This paper investigates the effectiveness of a novel feature for speech recognition called spectral subband centroids (SSC). SSC are computed as frequency centroids for each subband using the power spectrum of the speech signal. This feature can be obtained reliably even under noisy conditions because SSC are mainly computed from spectral peaks such as formants whose positions are almost unchanged in a noisy environment. Therefore, we can expect SSC to provide here useful information. Experimental results on Japanese spontaneous speech recognition showed that SSC produced significant improvements at SNR=10dB and 20dB when used as a supplemental feature to the conventional Mel-Frequency Cepstral Coefficients (MFCC). |
