Abstract
Presents evidence to support the claim that the space of trajectories of speech exists and may be approximated by a four-dimensional manifold which is nonlinearly embedded in both a space of LPC coefficients and also in a filter bank space. The authors also investigate the possibility that there are different dimensions for different phonetic categories, but find no evidence to support this hypothesis. The dimension is of interest since it is the smallest number of independent parameters needed to specify speech.<>
