International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: C. Hoelper P. Vary RWTH Aachen University Aachen Germany
Current speech, audio, and video coding and transmission systems are either analogue or digital, with a strong shift from analogue systems to digital systems during the last decades. We have combined both digital and ... 详细信息

IEEE Workshop on Speech coding Proceedings
作者: K. Al-Naimi S. Villette A. Kondoz Centre for Communication Systems Research (CCSR) University of Surrey Guildford Surrey UK
Vocoders compress speech by estimating model parameters at a given transmission rate over an analysis window, assuming that speech is stationary within this window. In this paper, the limits of this assumption are exp... 详细信息

Data Compression Conference (DCC)
作者: M. Slyz Lei Zhang Department of Electrical and Computer Engineering McMaster University Hamilton ONT Canada
We propose a hyperspectral image compressor called BH which considers its input image as being partitioned into square blocks, each lying entirely within a particular band, and compresses one such block at a time by u... 详细信息

International Conference on Signal Processing Proceedings (ICSP)
作者: Fan Jing Liu Huihua Sun Hai Department of Information & Communication Engineering Beijing Information Technology Institute China
A new method for recognizing the start and the end of each word in a Chinese continuous sentence is discussed. We define a new recognition characteristic called periodic gradual change (PGC). A continuous speech sente... 详细信息

作者: K.M. Malladi R.V. Rajakumar Hellosoft Inc. San Jose CA Dept. of E&ECE Indian Institute of Technology Kharagpur India
In this work, a new method for estimating the time-varying AR model of speech is presented. Here, the time-varying parameters are modeled as stationary processes. Both the time-varying parameters and their correspondi... 详细信息

IEEE International Symposium on Circuits and Systems (ISCAS)
作者: P. Alku Acoustics Laboratory Helsinki University of Technology Espoo Finland
A coding method, glottal linear prediction, that is based on a more precise model is introduced. According to this model, speech production can be separated into three processors: the glottal excitation, the vocal tra... 详细信息
