| Abstract(in English) | The hybrid algorithm of SMQ (Statistical Matrix Quantization) and HMM shows high performance in vocabulary-unspecific, speaker-independent speech recognition, however, it needs lots of computation and memory at a segment quantizer of SMQ. In this paper, we propose a newly developed, two-stage segment quantizer with a feature extractor based on KL-expansion and a classifier, both are traind by using competitive training of MCE/GPD. Result of experiments shows 1/30 1/40 reduction in both computation time and a memory size with the same perfomance that the old version of SMQ shows. |
