ASPI - Audiovisual to Articulatory Speech Inversion. European FET Project. [ASPI - Audiovisual to Articulatory Speech Inversion. European FET Project.]

ASPI has been an European FET project involving LORIA (France), KTH (Sweden), TUA (Greece), ENST (France) and ULB (Belgium). Audiovisual-to-articulatory inversion consists in recovering the vocal tract shape (from the vocal folds to the lips) dynamics from the acoustical speech signal, supplemented by image analysis of the speaker's face. The design of audiovisual-to-articulatory inversion involves two kinds of interdependent tasks. The first is the development of inversion methods that successfully answer the main acknowledged difficulties (non-unicity of inverse solution, a possible lack of phonetic relevancy of inverse solutions, impossibility of using standard spectral data), and the second is the construction of an articulatory database that comprises dynamic images of the vocal tract together with the speech signal uttered, and that for several male and female speakers.
