This is a unique resource that shows how most common speech sounds are actually produced. Most other resources use animations and diagrams, but this is the frist I see which show actual MRI scans. This is truly fascinating for anyone interested in phonetics, but also useful as a complement to other courses in pronunciation for Mandarin learners (including my own course). Click "IPA charts" for all the sounds, then click the sounds to see videos.

This online resource is a product of the collaboration between researchers at six Scottish Universities: the University of Glasgow, Queen Margaret University Edinburgh, Edinburgh Napier University, the University of Strathclyde, the University of Edinburgh and the University of Aberdeen.
