Fun with Vowel Formants

From somewhere on the internet I managed to find a table of numbers showing the formant frequencies for various vowels for the voices of men, women and children. Suddenly I wanted to use my discovery of WebAudio API to actually hear these sounded out. So I did this page.

Move your mouse over the different colored buttons and see if you can recognize the sounds of the vowels.
