Do You See What I’m Saying?: Ultrasound Technology As A Tool For Pronunciation Instruction
Abstract
Ultrasound technology aids pronunciation training because it makes visible what ordinarily is not. Ultrasound technology produces a real-time visual image of speech articulations that take place inside of the mouth; thus, it contributes visual input to an instructional context. This chapter first reports on investigatory applications of ultrasound within the context of second language instruction. Two pilot studies have been conducted which, although they did not return statistically significant results, pointed to high potentials for pedagogical efficacy in instructional settings. Ongoing use of the ultrasound in language classrooms at the University of Arizona underscores the ultrasound’s applicability to pronunciation training settings. In light of the positive results in the language classroom, the implications for ultrasound applications to speech language pathology are considered. Two broad areas of potential application are diagnosis and treatment practices. Challenges facing ultrasound-enhanced pronunciation instruction are subsequently discussed, and future directions are suggested for continued research into ultrasound technology as an instructional aide.
