Classification of cardiac arrhythmias using fuzzy ARTMAP
收藏 引用
IEEE TRANSACTIONS ON BIOMEDICAL ENGINEERING 1996年 第4期43卷 425-430页
作者: Ham, FM Han, S Florida Institute of Technology Electrical Engineering West University Blvd Melbourne FL USA Electrical Engineering Florida Institute of Technology Melbourne FL USA
We have investigated the QRS complex, extracted from electrocardiogram (EGG) data, using fuzzy adaptive resonance theory mapping (ARTMAP) to classify cardiac arrhythmias. Two different conditions have been analyzed: n... 详细信息

SPEAKER ADAPTIVE VECTOR QUANTIZATION OF LPC PARAMETERS OF SPEECH
收藏 引用
ELECTRONICS LETTERS 1988年 第22期24卷 1392-1393页
作者: LEE, KY KONDOZ, AM EVANS, BG Department of Electronic & Electrical Engineering University of Surrey Guildford UK
Recently, it has been shown that good quality speech at rates as low as 6 Kbit/s can be achieved with CELP and its derivatives. However, in bringing down the bit rate even further these coding schemes have resorted to... 详细信息

Spectral compensation for linear prediction of speech signals in coloured noise
收藏 引用
ELECTRONICS LETTERS 1998年 第11期34卷 1080-1081页
作者: Hu, HT Natl I Lan Inst Agr & Technol Dept Elect Engn I Lan 260 Taiwan
A method is presented to determine an appropriate portion that could be subtracted from the noise-contaminated autocorrelation functions before carrying out linear prediction analysis in coloured noise. This method gu... 详细信息

Enumeration and Trellis-Searched coding Schemes for Speech LSP Parameters
收藏 引用
IEEE TRANSACTIONS ON SPEECH AND AUDIO PROCESSING 1993年 第3期1卷 304-314页
作者: Malone, Kevin T. Fischer, Thomas R. Sandia Natl Labs Commun Syst Div Albuquerque NM 87185 USA Washington State Univ Sch Elect Engn & Comp Sci Pullman WA 99164 USA
Speech coders employing forward adaptive predictive coding (APC) and operating at medium-to-low bit rates necessitate efficient encoding of the linear predictive coding (LPC) coefficients. Line spectrum pair (LSP) par... 详细信息

LPC Spectral Moments for Clustering Acoustic Transients
收藏 引用
IEEE TRANSACTIONS ON SPEECH AND AUDIO PROCESSING 1993年 第3期1卷 362-368页
作者: Pinkowski, Ben Western Michigan Univ Dept Comp Sci Kalamazoo MI 49008 USA
Spectral moments (mean and coefficients of variation, skewness, and kurtosis) are assessed for 40 samples from 10 groups of acoustic transient signals differing in harmonic structure, duration, and degree of spectral ... 详细信息

Codebook-based Bayesian speech enhancement for nonstationary environments
收藏 引用
IEEE TRANSACTIONS ON AUDIO SPEECH AND LANGUAGE PROCESSING 2007年 第2期15卷 441-452页
作者: Srinivasan, Sriram Samuelsson, Jonas Kleijn, W. Bastiaan Royal Inst Technol Dept Signals Sensors & Syst SE-10044 Stockholm Sweden
In this paper, we propose a Bayesian minimum mean squared error approach for the joint estimation of the short-term predictor parameters of speech and noise, from the noisy observation. We use trained codebooks of spe... 详细信息

Exponential asymptotic stability of time-varying inverse prediction error filters
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 2000年 第7期48卷 1928-1936页
作者: López-Valcarce, R Dasgupta, S Tempo, R Fu, MY Univ Iowa Dept Elect & Comp Engn Iowa City IA 52242 USA Politecn Torino CENS CNR Turin Italy Univ Newcastle Dept Elect & Comp Engn Callaghan NSW Australia
It is a classical result of linear prediction theory that as long as the minimum prediction error variance is nonzero, the transfer function of the optimum linear prediction error filter for a stationary process is mi... 详细信息

Noncausal all-pole modeling of voiced speech
收藏 引用
IEEE TRANSACTIONS ON SPEECH AND AUDIO PROCESSING 1997年 第1期5卷 1-10页
作者: Gardner, WR Rao, BD QUALCOMM INC SAN DIEGO CA USA
This paper introduces noncausal all-pole models that are capable of efficiently capturing both the magnitude and phase information of voiced speech, It is shown that noncausal all-pole filter models are better able to... 详细信息
