چکیده

This paper presents a method for imaging the palate and extracting the palate contour from ultrasound images. Ultrasound does not usually capture the palate because the air at the tongue surface reflects the ultrasound beam back to the transducer. However, when the tongue touches the palate during a swallow, the ultrasound beam is transmitted through the soft tissue until it reaches and is reflected by the palate. In combination with tongue contours, the palate contour has the potential for disambiguation of the tongue surface, registration of images within and across subjects and for calculation of phonetically important measures.

What role does the palate play in speech motor control? Insights from tongue kinematics for German alveolar obstruents

By means of simultaneous EMMA and EPG recordings we investigated tongue tip kinematics and tongue palate contact patterns for four German speakers in order to compare production strategies of alveolar stops with fricatives. We assumed that the central nervous system integrates the palate in the speech motor control process and that tongue palate contact patterns influence the kinematic properti...

Spatial and dynamic aspects of retroflex production: An ultrasound and EMA study of Kannada geminate stops

This study investigates the production of geminate retroflex stops in Kannada using a combination of ultrasound and articulography. Data obtained from 10 native speakers of the language show that the retroflex gesture is dynamically complex and asymmetrical, involving an anticipatory retraction of the tongue tip, followed by the raising of this articulator towards the hard palate, and subsequen...
