Title
Evaluation of a system for concatenative articulatory visual speech synthesis
Abstract
A method for concatenative articulatory visual speech syn- thesis has been evaluated. The method consists in using concatenatedunitsofarticulatoryparametertransitionsfrom the middle of one phoneme to the middle of the next as in- put to a 3D parametric tongue model. The units were cre- ated by segmentation of the Electromagnetic articulography (EMA) measures in a database of 460 phoneticallybalanced sentences collected at the University of Edinburgh. The evaluation was made against the EMA database on which the movements were based and against X-ray films of three other speakers. The results show that the model replicates the natural movements globally, but that the rare units in the concatenation database may cause large differences be- tween the synthesized and the natural utterance and that the tongue root and tongue tip movements are too restricted in the model.
