A refinement is made in the nonlinear dynamic modeling of speech signals. Previous research successfully characterized speech signals as chaotic. Here, we analyze fricative speech signals using multifractal measures to determine various fractal regimes present in their chaotic attractors. Results support the hypothesis that speech signals have multifractal measures. {copyright} {ital 1996 American Institute of Physics.}
