SHORT-TERM TEMPORAL DECOMPOSITION AND ITS PROPERTIES FOR SPEECH COMPRESSION
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 1991年 第6期39卷 1282-1290页
作者: CHENG, YM OSHAUGHNESSY, D MCGILL UNIV DEPT ELECT ENGNMONTREAL H3A 2T5QUEBECCANADA
This paper deals with a technique of temporal speech compression, called temporal decomposition. A mathematical presentation of temporal decomposition is discussed from the point of view of speech production. We theor... 详细信息

Joint quantisation strategies for low bit-rate sinusoidal coding
收藏 引用
IET SIGNAL PROCESSING 2010年 第5期4卷 548-559页
作者: Unver, E. Villette, S. Kondoz, A. Univ Surrey Ctr Commun Syst Res Guildford GU2 7XH Surrey England
Although there are speech coding standards producing high-quality speech above 4 kbps, below that transparent quality has not been achieved yet. There is still room for improvement at lower bit rates, especially at 2.... 详细信息

GLOTTAL INVERSE FILTERING BY JOINT ESTIMATION OF AN AR SYSTEM WITH A linear INPUT MODEL
收藏 引用
IEEE TRANSACTIONS ON ACOUSTICS SPEECH AND SIGNAL PROCESSING 1986年 第1期34卷 28-42页
作者: MILENKOVIC, P WAISMAN CTR MENTAL RETARDAT & HUMAN DEV SPEECH MOTOR CONTROL LABSMADISONWI
Glottal inverse filtering is a technique by which the flow past the time varying glottal constriction is estimated by a filtering operation on the acoustic signal in human speech. The filtering operation removes the e... 详细信息

A FEEDBACK-CONTROL SYSTEM FOR REAL-TIME FORMANT ESTIMATION .2. ANALYSIS OF A HYSTERESIS EFFECT AND F2 ESTIMATION
收藏 引用
IEEE TRANSACTIONS ON BIOMEDICAL ENGINEERING 1993年 第9期40卷 892-898页
作者: ZIERHOFER, CM HOCHMAIR, ES Institut für Experimentalphysik Universität Innsbruck Innsbruck Austria
This paper presents the second part of the analysis of a feedback control system for real-time formant estimation. The system behavior is analyzed for an input signal composed of two sinusoids. If the frequency differ... 详细信息

Design and implementation of a parametric speech coder
收藏 引用
IEEE TRANSACTIONS ON CONSUMER ELECTRONICS 1998年 第1期44卷 163-169页
作者: Kwong, S Nui, PT City Univ Hong Kong Dept Comp Sci Hong Kong Hong Kong
Currently, it has been found out that speech coders based on linear predictive coding are good and accurate in modeling speech utterances. It does not only modeled speech utterance in an accurate manner but it also ha... 详细信息

R/D optimal linear prediction
收藏 引用
IEEE TRANSACTIONS ON SPEECH AND AUDIO PROCESSING 2000年 第6期8卷 646-655页
作者: Prandoni, P Vetterli, M Ecole Polytech Fed Lausanne Lab Commun Audio Visuelle CH-1015 Lausanne Switzerland Univ Calif Berkeley Dept Elect Engn & Comp Sci Berkeley CA 94720 USA
A common technique to extend linear prediction to nonstationary signals is time segmentation: the signal is split into small portions and the modelization is carried out locally, The accuracy of the analysis is, howev... 详细信息
