| Abstract(in English) | In recent works, vocal tract length normalization methods which achieve a remapping of the frequency axis using warping functions have been proposed for a large vocabulary speech recognition system. In this work, we introduce an estimation method of the parameter characterizing individual speakers, using the remapping of the frequency axis in cepstrum domain derived from all-pass transforms. In Japanese 5000-word task speech recognition experiments, we report reductions in word error rate of 7.1% absolute. When the normalization method is combined with CMN, word error rate reduction is 14.6%. |
