Animated X-ray Analyses of Speech

 

  

By Christine Ericsdotter

ABSTRACT

The goal of this project is to investigate 12 speakers with the x-ray equipment at Danderyd Hospital, that is especially calibrated for synchronous registration of articulatory movements and sound. Each subject is recorded for 20 seconds at 50 images per second. The x-ray films are of high quality, which facilitates the phonetic interpretation. The analysis is made frame by frame by tracing the speaker's vocal tract profile and by feeding the information from the different parts of the vocal tract profile (jaw, mandible, pharynx, tongue contour and lips) into the APEX model. At present, we are investigating how the movement of the tongue is modified when the tongue blade gestures for dental and retroflex stops interact with the tongue body motion for various VCV contexts

 

Present3D now supports CLUT with DICOM Volumes!

As part of the ongoing Joint Medical Visualisation Project with Aberdeen University, Present3D has now been updated to use Hounsfield Units and allow Colour Look Up Tables (CLUT) to be used. A full version of the above clip in side x side stereo can be downloaded from here:
