Background: This manuscript, the sixth in a series, discusses an investigation into production of lingua-alveolar stop consonants /tʌ/ and /dʌ/ by a person with congenital aglossia (PwCA), and the specific anatomical and physiological properties and kinematics involved.
Methods: In this study, a modified barium swallow study was performed to analyze the PwCA's oral and pharyngeal tract, in addition to a video speech recording made during a series of imitative tasks isolating specific English phonemes (/tʌ/ and /dʌ/). Researchers evaluated the PwCA's vertical and horizontal range of motion (ROM) of the mobile articulators (i.e., mylohyoid, tongue base, lower incisors, hyoid) during /tʌ/ and /.. View More»
