Some speech coding schemes are descripted in this paper. They are based on concepts related to the fractal theory. Although algorithms for compressing signals have already appeared in the literature, none of them is concentrated to the speech signal in particular. It is useful, instead, to take advantage of the knowledge concerning classical schemes of speech coding. The described algorithms are based on the fractal interpolation and on signal modeling by fractal related parameters. It will be shown that fractal techniques can successfully be used for coding speech.

Keywords: fractal interpolation, fractal dimension, speech coding.
