Visualization for improving foreign language pronunciation

Speaking coherently in a second language requires knowledge and execution of pronunciation. Often, pronunciation training is seldom emphasized in language learning. However, explicitly teaching pronunciation can increase confidence and attitudes towards pronunciation in learners. We present a visual feedback system for vowels using a speaker calibrated vowel chart. The demo includes vowel chart calibration, an interactive tutorial for learning how to read a vowel chart, and a practice page for three vowel minimal pairs.
