title: Characterization of attractors in speech signals.
abstract: It is shown that speech signals can have attractors with fractal dimension. A method for estimating this dimension is given. The existence of this attractor suggests that statistical models for speech may be inappropriate. Moreover, the dimension of this attractor is a lower bound on the order of a linear prediction model.
