Lingual ultrasound imaging is essential in linguistic research and speech recognition. It has
been used widely in different applications as visual feedback to enhance language learning …

Reviewed here are methods developed for following (ie, tracking) structures in medical B-
mode ultrasound time sequences during large-scale motion. The resulting motion estimation …

Correlation filter-based trackers (CFTs) have recently shown remarkable performance in the
field of visual object tracking. The advantage of these trackers originates from their ability to …

Abstract The term “Silent Speech Interface” was introduced almost a decade ago to describe
speech communication systems using only non-acoustic sensors, such as …

One application of medical ultrasound imaging is to visualize and characterize human
tongue shape and motion in real-time to study healthy or impaired speech production. Due …

For speech research, ultrasound tongue imaging provides a non-invasive means for
visualizing tongue position and movement during articulation. Extracting tongue contours …

Analyses of the human tongue motion as captured from 2D dynamic ultrasound data often
requires segmentation of the mid-sagittal tongue contours. However, semi-automatic …

The goal of this study was to characterize errors involved in obtaining midsagittal tongue
contours from two-dimensional ultrasound image sequences. Toward that end, two basic …

Ultrasound imaging is becoming a practical tool in silent speech recognition. It is a
challenge to accurately extract tongue contours due to the soft tissue characteristics of the …

Ultrasound technology is safe, relatively affordable, and capable of real-time performance.
Recently, it has been employed to visualize tongue function for second language education …
