Abstract : Acoustic-to-articulatory maps based on articulatory models have typically been evaluated in terms of acoustic accuracy, that is, the distance between mapped and observed acoustic parameters. In this paper we present a method that would allow for the evaluation of such maps in the articulatory domain. The proposed method estimates the parameters of Maeda's articulatory model on the basis of electromagnetic articulograph data, thus producing full midsagittal views of the vocal tract from the positions of a limited number of sensors attached on articulators.
