Abstract

The paper analyses how variations of the parameters of the Liljencrants-Fant (1985) model of glottal flow influence the speech spectrum, in order to determine the spectral relevance of these parameters. The effects of small parameter variations are described analytically. This analysis also gives an indication to what extent the LF parameters can be estimated reliably from the speech spectrum. The effects of larger parameter variations are discussed with the help of figures. Results are presented for a number of sets of estimated glottal-pulse parameters that were taken from the literature. The main conclusion is that the LF model, which, given the fundamental period, is a three-parameter model, actually operates as a one- or a two-parameter model.
