Some speech coding schemes are described 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 on the speech signal. 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 succesfully be used for coding speech.
