The ArtSpeechMRIfr database contains  real-time films ((rtMRI) as well as static magnetic resonance images (3D MRI)  of the vocal tract. The database contains also processed data: denoised audio, its phonetically aligned annotation, articulatory contours, and vocal tract volume information, which … Continuer la lecture →

The extraction of the speech articulator  contours  from real-time magnetic resonance images is a nontrivial task due to the presence of artifacts manifesting in form of blurring or ghostly contours. In this work we present results of automatic tongue delineation … Continuer la lecture →

This page shows a few examples of copy synthesized French utterances. The aim of copy synthesis is to simulate speech from films of the vocal tract. The geometry of the vocal tract is defined via an articulatory model derived from … Continuer la lecture →

The possibility to model a glotal chink is also important to simulate fricatives, and especially voiced fricatives [1]. Indeed, voiced fricatives require both a voiced source, generated by the oscillating vocal folds, and a sufficiently large volume velocity through the … Continuer la lecture →
