作者: D.G. Kimber M.A. Bush G.N. Tajchman Xerox Palo Alto Research Center Palo Alto CA USA
A set of experiments in which the LVQ2 (learning vector quantization) algorithm of T. Kohonen et al (Proc. 1988 IEE Int. Conf. on Neural Networks, p.I-61-68, 1988) is used to generate vector codebooks for a discrete-o... 详细信息

International Conference on Signal Processing Proceedings (ICSP)
作者: Deng Lixin Yang Zhen Zheng Baoyu Information Engineering Department Nanjing University of Posts and Telecommunications China
We present in this paper a new binomial sine pulse (BSP) excitation signal used in linear prediction-based speech codecs. The structure of the BSP excitation signal is actually a sine wave whose amplitude is modulated... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: R.A. Sukkar J.G. Wilpon AT and T Bell Laboratories Inc. Naperville IL USA
A classifier for utterance rejection in a hidden Markov model (HMM) based speech recognizer is presented. This classifier, termed the two-pass classifier, is a postprocessor to the HMM recognizer, and consists of a tw... 详细信息
