Abstract

Acoustic-to-articulatory mapping is the determination of the parameters of a model of the vocal tract so that its first few eigenfrequencies agree with a set of observed formant frequencies. The article presents an analytical method for acoustic-to-articulatory mapping, which is generic. The plausibility of computed vocal tract shapes is examined and methodological problems as well as possible applications are considered.
