We describe in this paper a code-excited linear predictive coder in which the optimum
innovation sequence is selected from a code book of stored sequences to optimize a given …

Traditional parametric coding of speech facilitates low rate but provides poor reconstruction
quality because of the inadequacy of the model used. We describe how a WaveNet …

For low bit rate speech coding applications, it is important to quantize the LPC parameters
accurately using as few bits as possible. Though vector quantizers are more efficient than …

An in-depth treatment of algorithms and standards for perceptual coding of high-fidelity
audio, this self-contained reference surveys and addresses all aspects of the field. Coverage …

Speech and audio compression has advanced rapidly in recent years spurred on by cost-
effective digital technology and diverse commercial applications. Recent activity in speech …

This paper describes an effective and efficient time domain speech encoding technique that
has an appealing low complexity, and produces toll quality speech at rates below 16 kbits/s …

Linear predictive coding (LPC) parameters are widely used in various speech coding
applications for representing the short-time spectral envelope information of speech [1]. For …

A Practical Handbook of Speech Coders offers in-depth treatment of the basics of speech
coding plus the innovations to the basic methods that make the coders useful and efficient. It …

Prediction error filters which combine short-time prediction (formant prediction) with long-
time prediction (pitch prediction) in a cascade connection are examined. A number of …

Voiced speech is interpreted as a concentration of slowly evolving pitch-cycle waveforms.
This signal can be reconstructed by interpolation from a downsampled sequence of pitch …
