Based on the recently developed chaos and fractal theories
this paper introduces new methods for speech signal processing.A novel phase space reconstruction algorithms is proposed for speech signal
the distributions of the maximum Lyapunov exponent and the fractal dimension of speech signal are tested and analyzed statistically
and a new low bit rate speech coding method based on fractal code excited linear prediction is presented.The results of this study indicate that chaos and fractal theories have great potentials in the field of speech signal processing.
