URSI International Symposium on Signals, Systems, and Electronics (ISSSE)
作者: S.A. Fattah W.-P. Zhu M.O. Ahmad Centre for Signal Processing and Communications Department of Electrical and Computer Engineering Concordia University Montreal QUE Canada
In this paper, a new scheme for the estimation of formant frequencies of noise-corrupted speech signals is presented. A once-repeated autocorrelation function (ORACF) of the observed noisy speech signal is proposed to... 详细信息

IEE Colloquium on Security and Cryptography Applications to Radio Systems
作者: C.S. Xydeas D.J. Hiotakakos C.A. Boyd Speech of Processing Research Laboratory Electrical Engineering Department University of Manchester Institute of Science and Technology UK
Source coding and encryption are linked theoretically by the aim of removing redundancy. However, so far, no attempt has been made to combine source coding and encryption together, except in lossless compression model... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: R. Soheili A.M. Kondoz B.G. Evans Centre for Satellite Engineering Research University of Surrey UK
An excitation modeling based on a multitap adaptive or fixed codebook is proposed for low-delay encoding of speech signals. The algorithm can produce high-quality speech at bit rates of 8 kbit/s, but it is still lacki... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: D. Wong B. Juang D. Cheng Speech Technology and Research Laboratory Santa Barbara CA USA Bell Laboratories Holmdel NJ USA University of California Santa Barbara CA USA
Frame predictive vector quantization is developed to compress the bit rate for coding the LPC filter coefficients to under 250 bits/sec. An innovative LPC compression technique, matrix quantization, is also developed ... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: J. Olive Bell Laboratories Murray Hill NJ USA
Peterson, Wang, and Sivertsen[1] suggested the use of the units called "dyads" as the basic unit for speech synthesis. This paper describes an approach to speech synthesis by rule which uses a unit that is s... 详细信息
