摘要：

Fractal geometry, a relatively young branch of mathematics, offers new ways of evaluating the irregularity of the physiologic and acoustic aspects of speech. The validity and reliability of a box-counting method for estimating the fractal dimension (DF) of the period and amplitude of vocal signals were demonstrated, and the method was applied to sustained vowels produced by four men and four women. Mean DF of the fundamental period was 1.46; DF of the amplitude records averaged a slightly, but significantly, higher 1.54. The potential of DF as a research and clinical tool is considered. © 1990 Raven Press, Ltd., New York.
