摘要: The paper reports recent efforts to further improve the performance of Sphinx system for speaker-independent continuous speech recognition. recognition error rate is significantly reduced with incorporation additional dynamic features, semi-continuous hidden Markov models, and speaker clustering. For June 1990 (RM2) evaluation test set, rates our current are 4.3% 19.9% word-pair grammar no respectively.
