EFFICIENT SOLUTION OF COVARIANCE EQUATIONS FOR linear PREDICTION
收藏 引用
IEEE TRANSACTIONS ON ACOUSTICS SPEECH AND SIGNAL PROCESSING 1977年 第5期25卷 429-433页
作者: MORF, M DICKINSON, B KAILATH, T VIEIRA, A STANFORD UNIV INFORMAT SYST LABSTANFORDCA 94305 PRINCETON UNIV DEPT ELECT ENGN & COMP SCIPRINCETONNJ 08540
An algorithm for the solution of the linear equations for the "covariance method" of linear prediction is stated and proved. The algorithm requires only O(p 2 ) arithmetic operations, and in form resembles t... 详细信息

IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT 1977年 第4期26卷 292-295页
作者: MARTINI, C RIDELLA, S CNR CIRCUITI ELETTR LABI-16145 GENOAITALY UNIV GENOA DEPT ELECT ENGNI-16132 GENOAITALY
The broad-band (2-18 GHz) optimum steps of a commercial sliding load have been determined by simulation on a digital computer. The influence of the load, which is slided, is taken into account. The results have been t... 详细信息

STATISTICAL TESTS AND DISTANCE MEASURES FOR LPC COEFFICIENTS
收藏 引用
IEEE TRANSACTIONS ON ACOUSTICS SPEECH AND SIGNAL PROCESSING 1977年 第6期25卷 554-559页
作者: DESOUZA, P UNIV OTAGO SCH MED DEPT PREVENT & SOCIAL MED DUNEDIN NEW ZEALAND
This paper considers the problem of comparing two sets of (LPC) coefficients or, more generally, that of comparing two short segments of speech via LPC techniques. It is shown that Itakura's prediction-residual ra... 详细信息

On Reflection Coefficients and the Cholesky Decomposition
收藏 引用
IEEE Transactions on Acoustics, Speech, and Signal Processing 1977年 第1期25卷 93-96页
作者: Gibson, Jerry D. Department of Electrical Engineering University of Nebraska Lincoln NE 68588 United States
The autocorrelation and covariance methods are the two most popular analysis techniques for linear predictive coding of speech. Recent work on the covariance method has utilized the Cholesky decomposition for solving ... 详细信息

A subjective evaluation of pitch detection methods using LPC synthesized speech
收藏 引用
IEEE Transactions on Acoustics, Speech, and Signal Processing 1977年 第3期25卷 221-229页
作者: C. McGonegal L. Rabiner A. Rosenberg Bell Laboratories Inc. Murray Hill NJ USA
A subjective evaluation of seven pitch detectors has been carried out using synthetic speech. The evaluation is intended to complement the objective performance evaluation of the same pitch detection algorithms in the... 详细信息

A pitch extraction algorithm based on LPC inverse filtering and AMDF
收藏 引用
IEEE Transactions on Acoustics, Speech, and Signal Processing 1977年 第6期25卷 565-572页
作者: Chong Un Shih-Chien Yang SRI International Inc. Menlo Park CA USA Korea Advanced Institute of Science and Technology Seoul South Korea Chung-Shan Institute of Sciences and Technology Lungtan Taiwan
We present an efficient algorithm for determining fundamental frequency and voiced/unvoiced (V/UV) decision of speech. The pitch extractor utilizes the cross-correlation average magnitude difference function (AMDF) wa... 详细信息
