Combined analysis of real-time three-dimensional tongue ultrasound and digitized three-dimensional palate impressions: Methods and findings
Steven M. Lulich · The Journal of the Acoustical Society of America · 2014
Vocal tract and articulatory imaging has a long and rich history using a wide variety of techniques and equipment. This presentation focuses on combining real-time 3D ultrasound with high-resolution 3D digital scans of palate impressions. Methods for acquiring and analyzing these data will be presented, including efforts to accomplish 3D registration of the tongue and hard palate. Findings from an experiment investigating inter-speaker variability in palate shape and vowel articulation will also be presented.
