From real-time MRI to 3D tongue movements
2004 (English)In: INTERSPEECH 2004: ICSLP 8th International Conference on Spoken Language Processing / [ed] Kim, S. H.; Young, D. H., 2004, 1109-1112 p.Conference paper (Refereed)
Real-time Magnetic Resonance Imaging (MRI) at 9 images/s of the midsagittal plane is used as input to a threedimensionaltongue model, previously generated based onsustained articulations imaged with static MRI. The aimis two-fold, firstly to use articulatory inversion to extrapolatethe midsagittal tongue movements to three-dimensionalmovements, secondly to determine the accuracy of thetongue model in replicating the real-time midsagittal tongueshapes. The evaluation of the inversion shows that the realtimemidsagittal contour is reproduced with acceptable accuracy.This means that the 3D model can be used to representreal-time articulations, eventhough the artificially sustainedarticulations on which it was based were hyperarticulated andhad a backward displacement of the tongue.
