Using Arai's Vocal Tract Models for Education in Phonetics

Terri Lander, Takayuki Arai

Dr. Arai's vocal tract models are used for instruction in a three-day Acoustic Phonetics short course taught at Northwest Christian College in Eugene, Oregon, as a part of the year 2002 Oregon Summer Institute of Linguistics. Arai's vocal tract models, designed as educational tools, are found to help students grasp basic concepts in acoustic phonetics, particularly source filter theory. A perceptual experiment investigates human perception of the output of the models at a fine phonetic level. A questionnaire reveals that students used the models to improve vowel discrimination during the perceptual experiment, and a written exam reveals students' solid understanding of the interaction between source and filter, both of which are fundamental concepts in source filter theory. Finally, we examine the students' label selections for the perceptual study and discuss implications for speech annotation.
