IEEE Conference on Decision and Control
作者: D.E. Miller Li Qiu Department of Electrical and Computer Engineering University of Waterloo Waterloo ONT Canada Department of Electrical and Electronic Engineering Hong Kong University of Science and Technology Kowloon Hong Kong China
Here we consider the problem of providing near optimal performance for a large set of possible models. We adopt the H ∞ framework in the single-input single-output (SISO) setting with structured uncertainty: a compac... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: A. Gersho T. Ramstad I. Versvik Department of Electrical and Computer Engineering University of California Santa Barbara CA USA Division of Telecommunications Norwegian Institute of Technology Trondheim Norway Nesbru Norway
Vector quantization (VQ) is examined as a technique to enhance performance in subband coding of speech at 9.6 kb/s. The set of short-term subband power levels is vector quantized, providing low-rate side information t... 详细信息

IEEE International Conference on Image Processing
作者: Bo Li Hong Chang Shiguang Shan Xilin Chen School of Computer Science and Technology Harbin Institute of Technology Harbin China Chinese Academy of Sciences Beijing Beijing CN
In this paper, we revisit the manifold assumption which has been widely adopted in the learning-based image super-resolution. The assumption states that point-pairs from the high-resolution manifold share the local ge... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: H. Morikawa H. Fujisaki Faculty of Engineering University of Tokyo Bunkyo Tokyo Japan
The ARMA model provides an effective means for precise representation of the speech production process. A stable and accurate estimation of ARMA parameters from the speech signal has been shown to be possible by the S... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: P. Prandom M. Goodwin M. Vetterli LCAV Ecole Polytech. Fed. de Lausanne Switzerland EECS University of California Berkeley USA LCAV Ecole Polytechnique Fédérale de Lausanne Switzerland
The idea of optimal joint time segmentation and resource allocation for signal modeling is explored with respect to arbitrary segmentations and arbitrary representation schemes. When the chosen signal modeling techniq... 详细信息

Midwest Symposium on Circuits and Systems (MWSCAS)
作者: H.K. Kwan T.X. Li Electrical and Computer Engineering Faculty of Engineering University of Windsor Windsor ONT Canada
In this paper, we introduce an auto-regressive moving average (ARMA) lattice model for speech modeling. The speech characteristics are modeled and expressed in the form of lattice reflection coefficients for classific... 详细信息

National Conference on Communications (NCC)
作者: Abhijit Pradhan Sadhana Chevireddy Kamakoti Veezhinathan Hema Murthy Department of Computer Science Indian Institute of Technology Madras Chennai India
In speech coding, segment vocoders offer good intelligibility at low bit rates. A segment vocoder has four basic components 1) Segmentation of input speech 2) Segment quantization 3) Residual quantization 4) Synthesis... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: R. Mizoguchi M. Yanagida O. Kakusho Institute of Scientific and Industrial Research Osaka University Suita Osaka Japan
linear prediction method is one of the most frequently used analysis methods of speech. Covariance method and auto-correlation method of linear prediction often fail to make a precise analysis of speech because of the... 详细信息

IEEE International Symposium on Circuits and Systems (ISCAS)
作者: Y. Kuroiwa T. Shimamura Department of Information and Computer Sciences Saitama University Urawa Japan
In this paper, we propose a pitch synchronous addition method for LPC analysis by making use of the periodicity of speech. It is shown that the solution overcomes the difficulty involved with the technique of noise re... 详细信息
