Sixth European Conference on Speech Communication and Technology
In this paper we compare
several ADPCM schemes with nonlinear prediction based on neural nets with
the classical ADPCM schemes based on several linear prediction schemes.
Main studied variations of the ADPCM scheme with adaptive quantization
(2 to 5 bits) are:
-forward vs backward
-sample adaptive vs block adaptive.
