ArtSpeechMRIfr database
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
Tracking speech articulators in MRI films
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
Examples of articulatory copy synthesis
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
Synthesis of voiced/unvoiced fricatives
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
Mucus influence on the vocal folds
Aim The production of voiced sounds is essentially linked to the auto-oscillation of the vocal folds. This phenomenon is the result of a fluid-structure interaction between the airflow coming from the lungs and the vocal folds’ elastic tissues (Figure 1). The … Continuer la lecture
SIBILANT FRICATIVES : /s/, /f/, etc.
From a physics point of view, sibilant fricative sound production is generally described as noise produced due to the interaction of a turbulent jet, issued from a constriction between the tongue and the hard palate – i.e. the sibilant groove … Continuer la lecture
