Near-optimum linear predictive speech coding

[Proceedings] GLOBECOM '90: IEEE Global Telecommunications Conference and Exhibition, 2002
A near-optimum linear-predictive speech coding scheme is proposed. Near-optimum performance is defined in terms of minimizing a perceptually weighted mean-squared-error distortion measured directly between the original speech and the reconstructed speech.

Continuous representations in linear predictive coding

[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991
A major source of audible distortion in current low-bit-rate speech coding algorithms is an inaccurate degree of periodicity of the voiced speech signal. If the correlations between neighboring pitch cycles are accurately reproduced, these audible distortions can be reduced significantly.

A Survey of Linear Predictive Coding: Part I of Linear Predictive Coding and the Internet Protocol

Foundations and Trends® in Signal Processing, 2010
Linear prediction has long played an important role in speech processing, especially in the development during the late 1960s of the first low bit rate speech compression/coding systems. The approach, which eventually became known as linear predictive coding (LPC), coincidentally came to fruition at the right time to be adopted as the speech ...

Efficient codebook structure for code excited linear prediction coding

The Journal of the Acoustical Society of America, 1997
A speech communication system using a code excited linear prediction speech decoder. The decoder using a first codebook containing a first digital value sequence selected from the set of binary values {0, 1}. The decoder also using a second codebook containing a second digital value sequence having values selected from the set of binary values {−1, 0}.

Relaxed Code-Excited Linear Prediction (RCELP)

2017
While code-excited linear prediction shows good performance for bitrates above 8 kbits/s, the quality of the speech-specific waveform coding scheme drops noticeably at lower rates. At such low rates, all information included in the waveform of the speech cannot be correctly coded.

Linear Prediction Techniques in Speech Coding

1991
Recent advances in speech coding algorithms and techniques based on the use of linear prediction now permit high quality voice reproduction at remarkably low bit rates. This paper reviews some of the main ideas underlying the algorithms of major interest today. The concept of removing redundancy by linear prediction is reviewed, first in the context of
