International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: D. Tuffelli B. Groc E.N.S. d'Electronique et de radioélectricite Grenoble
At learning, LPC is used to get the reference poles corresponding to the words. During the recognition, the order of the filtering is variable and imposed by the dictionary. The distance between an input speech window... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: F. Villavicencio A. Robel X. Rodet Analysis-Synthesis team I. R. C. A. M. Paris France
n this work we address the problem of all pole spectral envelope estimation for speech signals. The currently widely used all pole spectral envelope model suffers from well-known systematic errors and more severely fr... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: P. Chu D. Messerschmitt Department of Electrical Engineering and Conputer Science University of California Berkeley CA USA
A new spectral distance measure is defined by inserting a multiplicative frequency weighting term into the conventional Itakura-Saito measure. Then the weighting function is a simple one pole function, then the minimi... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: G. Borsuk M. White Westinghouse Advanced Technology Laboratories Baltimore MD USA
A monolithic CCD adaptive filter chip is described which implements the Widrow-Hoff "clipped-data" LMS adaptive algorithm. The chip can be used as a pre-filter noise canceller, analysis filter, or pre-whiten... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: R. Hagen E. Ekudden Research Ericsson Radio Systems Audio and Visual Technology Sweden
This paper describes an 8 kbit/s ACELP speech coder with high performance for both speech and non-speech signals such as background noise. While the traditional waveform matching LPAS structure employed in many existi... 详细信息
