International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: M. Berouti J. Makhoul Bolt Beranek and Newman 슠Inc. Cambridge MA USA
In embedded multirate speech coding, it is desired to have a transmitter/receiver system that operates efficiently over a wide range of channel transmission rates. We are currently investigating a system based on adap... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: Y. Kobayashi Y. Niimi Department of Computer Science Kyoto Technical University Kyoto Japan
The pitch contour plays an important role of marking syntactic boundaries in the natural language. In order to improve the continuous speech recognition system we have developed, we have carried out experiments on how... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: R. Wiggins J. Parry Central Research Laboratories Texas Instruments Inc. Dallas TX USA Department of Electrical Engineering University of Arizona Tucson Tucson AZ USA
Inverse filter parameters may be determined from estimates of the autocorrelation or covariance of a sampled signal by methods which admit corruption of partial results and generate subsequently optimal values for the... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: S. Maitra S. Foster C. Davis Systems Control Technology Inc. Palo Alto CA USA
linear predictive coding of speech has traditionally used a least mean square (LMS) criterion for determining the optimal filter parameters. Auto-regressive (AR) models using LMS are in wide-spread use for low bit rat... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: R. Wohlford A. Smith M. Sambur ITT Defense Communications Division San Diego CA Defense Communications Division ITT San Diego CA USA
This paper presents results of research on the enhancement of speaker independent wordspotting in conversational, telephone bandwidth speech from a variety of talkers. The research involved the comparison of five LPC ... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: C. Hodges T. Barnwell D. McWhorter School of Electrical Engineering Georgia Institute of Technology Atlanta GA USA
This paper presents a unique approach for the implementation of the speech synthesis portion of a LPC vocoder. The implementation uses eight LSI-11 microprocessors operating synchronously around a time division multip... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: J. Olive Bell Telephone Laboratories Inc. USA
In previous papers we discussed a speech synthesis by rule scheme where segments obtained from natural speech were linearly concatenated. These segments included the consonants and the transitions from consonants to v... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: J.-P. Adoul J.-L. Debray D. Dalle Communication Research Center University of Sherbrooke Sherbrooke QUE Canada
This paper explores the intermediate solutions between fixed prediction and forward adaptative prediction in ADPCM which consists of using a finite number, L, of preselected linear predictors of order M. The design pr... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: J. Tribolet R. Crochiere Bell Laboratories Murray Hill New Jersey Bell Laboratories Murray Hill NJ USA
The purpose of this paper is to describe a scheme for low-bit-rate transmission of speech. The scheme consists of a cascade of a codec with a post-processor. The codec is based on a modified version of the LPC Vocoder... 详细信息

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)
作者: P. Papamichalis T. Barnwell School of Electrical Engineering Georgia Institute of Technology Atlanta GA USA
For many sounds, the successive frames of a speech signal do not differ significantly, and they can be represented by the same set of parameters (PARCOR coefficients). This paper examines the possibility of transmitti... 详细信息
