Combining MRI, EMA and EPG measurements in a three-dimensional tongue model

Using linguopalatal contact patterns to tune a 3d tongue model

The six articulatory parameters of a three-dimensional tongue model were adjusted to replicate linguopalatal contact patterns measured with Electropalatography (EPG). The tongue model is based on artificially sustained articulations measured with MRI and the EPG data provides one possibility to tune the parameters to dynamic speech. A 3D model was generated of the palate and the electrode distr...

Making the tongue model talk: merging MRI & EMA measurements

Electromagnetic articulography (EMA) data collected with the Movetrack measurement system has been used to set the parameter values in a three-dimensional tongue model dynamically. The outputs from four of the receiver coils are used in the parameter control; the data from the coil on the lower incisor for the jaw height parameter and the three coils on the tongue, T1-T3, for the parameters of ...

Modeling the Talking Tongue

Electromagnetic articulography (EMA) and Electropalatography (EPG) data has been used to adjust the shape and the movement of a three-dimensional tongue model to follow the articulations of the reference subject. The EMA data was used to control the dynamics of the parameters of a three-dimensional tongue model, whereas the EPG data was used to tune the six articulatory parameters to replicate ...

Are static MRI measurements representative of dynamic speech? results from a comparative study using MRI, EPG and EMA

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-toelectropalatographic mapping and demonstra...
