The Wikipedia article on electropalatography makes strange reading if, like me, you think of that technique as something developed for research in phonetics. The article is very dull, and makes no reference to phonetics, covering only the commercial exploitation of EPG for therapeutic purposes. No pictures and no data. It really needs some illustration from the many studies that have been carried out using EPG for phonetic research. I hope I can do something to improve it, but it would be good if others could contribute.
