| Abstract(in English) | This paper presents a simple and efficient time domain technique to estimate all-poll model on mel-frequency axis(Mel-LPC), and evaluates the performance in the large vocabulary continuous speech recognition with 114 monosyllable HMMs. Firstly, the optimal value of frequency warping factor is examined through monosyllable accuracies in a 20,000 vocabulary recognition without language models. The optimal value at the sampling frequency of 16kHz is 0.60 for male speaker and 0.40 for female speaker, respectively. With language models, Mel-LPC cepstrum attains the word accuracies of 93.0% for male speakers and 93.1% for female speakers, which are 2.1% and 1.7% higher than those of the LPC mel-cepstrum, respectively. This performance is slightly superior to that of MFCC. |
