Title: What the Ear Doesn't Hear: Representing the Articulators
Abstract: Each spoken language has its own acoustic footprint, the sounds and sound
patterns that characterize the way the language sounds. The distinct sounds are
created by the exquisite temporal coordination of different
configurations of the articulators (tongue, lips, etc.). Until recently, most
of our understanding of the movements of the tongue came indirectly, from
interpreting the audio signal. However, in recent years, linguists have begun
to explore lingual articulation through the use of ultrasound imaging.
Ultrasound imaging for speech presents a number of data management issues, from data extraction to storage to analysis. The work presented here, a collaboration with Ian Fasel (SISTA), lays out some of the these issues and our approach to solving them.
