Abstract [en]

This paper presents an evaluation method for statistically basedspeech inversion, in which the estimated vocal tract shapes are classified intophoneme categories based on the articulatory correspondence with prototypevocal tract shapes. The prototypes are created using the original articulatorydata and the classifier hence permits to interpret the results of the inversion interms of, e.g., confusions between different articulations and the success in estimatingdifferent places of articulation. The articulatory classifier was used toevaluate acoustic and audiovisual speech inversion of VCV words and Swedishsentences performed with a linear estimation and an artificial neural network.
