A Visual Language Learning Tool. University of British Columbia

This site is for everybody who is interested in language and speech sounds. Thanks to the development of ultrasound technology, we are able to observe what is happening inside the mouth when you articulate speech sounds. This site was born out of a collaboration of the Department of Linguistics and the Department of Asian Studies, so that linguists could apply ultrasound technology to test biovisual feedback in the context of the language learning, and Japanese instructors could provide students with video materials to help them to improve their pronunciation outside the class. Our tech team developed ultrasound overlay videos, in which ultrasound images of tongue movements in speech are superimposed on videos of a face, so you can see how the facial muscles and tongue muscles coordinate with each other. 

We invite you to explore our website and learn more about our pronunciation teaching resources and research projects on the use of ultrasound in pronunciation instruction.
