Some Considerations in the Cinefluorographic Analysis of Tongue Movements during Speech

摘要

This paper discusses techniques in the application of cinefluorography to the study of speech and presents sample data to illustrate such techniques. The data pertain to movements of the tongue, jaw, and hyoid bone in the midsagittal plane. In the case of the tongue, small radiopaque markers were attached to the midline of this structure; and the cineradiographs were used to record the planar displacement patterns of the markers. The primary objective of the analysis methods is the investigation of the intrastructural and interstructural relationships in lingual articulation.
