Bauer on ultrasound in linguistic research

Matt Bauer (Illinois Institute of Technology) will be giving  a special presentation the use of ultrasound  in linguistic research at 10:30am on May 11, 2009 in the Landahl Center for Linguistic Research. A short description of this presentation is given below:

The use of ultrasound in linguistic research represents a non-invasive, easy to use, portable, and (relatively) inexpensive tool to study speech-related anatomical structures, such as the tongue, hard palate, and larynx. Ultrasound is particularly well suited for directly measuring ‘slow’ lingual gestures, such as those for vowels and liquids, as opposed to ‘fast’ gestures, such as the ones for flaps and trills. Laryngeal height can be measured indirectly through the movement of the hyoid bone. This talk will cover the basics of ultrasound technology, recording procedures, data analysis, and advantages and disadvantages of using ultrasound in linguistic research.
