Enhancing Acoustic-to-EPG Mapping with Lip Position Information

This paper investigates the hypothesis that cues involving the positioning of the lips may improve upon a system that performs a mapping from acoustic parameters to electropalatographic (EPG) information; that is, patterns of contact between the tongue and the hard palate. We adopt a multilayer perceptron as a relatively simple model for the acoustic-to-electropalatographic mapping and demonstrate that its performance is improved when parameters describing the positioning of the lips recorded by means of electromagnetic articulography (EMA) are added to the input of the model.
