Visual Learning 2: Pronunciation App Using Ultrasound, Video, and MRI

Kyori Suzuki, Ian Wilson, Hayato Watanabe


We demonstrate Visual Learning 2, an English pronunciation app for second-language (L2) learners and phonetics students. This iOS app links together audio, front and side video, MRI and ultrasound movies of a native speaker reading a phonetically balanced text. Users can watch and shadow front and side video overlaid with an ultrasound tongue movie. They are able to play the video at three speeds and start the video from any word by tapping on it, with a choice of display in either English or IPA. Users can record their own audio/video and play it back in sync with the model for comparison.
