International Joint Conference on Neural Networks (IJCNN)
作者: Sin Wee Lee D. Palmer-Brown Computational Intelligence Group School of Computing Leeds Metropolitan University Leeds UK School of Computing and Technology University of East London London UK
This paper presents a new application of the snap-drift algorithm by S. W. Lee, et al. (2004): phrase recognition using a set of phrases from the Lancaster parsed corpus (LPC) by R. Garside, et al. (1987). The learnin... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: L.P. Netsch G.R. Doddington Computer Science Laboratory Texas Instruments Inc. Dallas TX USA SRI International Inc. Menlo Park CA USA
A text-dependent method of speaker verification processing which utilizes the statistical correlation between measured features of speech across whole words is described. The correlation is used in a linear discrimina... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: Y. Hussain N. Farvardin Electrical Engineering Department and Systems Research Center University of Maryland College Park MD USA
The authors describe a noisy channel finite-state vector quantizer (FSVQ) for quantizing speech line spectrum pair (LSP) parameters. First they show that under noiseless channel conditions, the ordinary FSVQ of J. Fos... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: L. Rabiner M. Sondhi S. Levinson Bell Laboratories Murray Hill NJ USA
The theory of vector quantization (VQ) of linear predictive coding (LPC) coefficients has established a wide variety of techniques for quantizing LPC spectral shape to minimize overall spectral distortion. Such vector... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: S. Wang A. Gersho Center for Information Processing Research Department of Electrical and Computer Engineering University of California Santa Barbara CA USA
Several major modifications to the phonetically segmented vector excitation coding (PS-VXC) coder by the authors (1989, 1990) reported previously have resulted in enhanced speech quality while reducing the delay, comp... 详细信息
