Welcome to our interactive International Phonetic Association (IPA) chart website! Clicking on the IPA symbols on our charts will allow you to listen to their sounds and see vocal-organ movements imaged with ultrasound, MRI, or in animated form. To find out more about how our IPA charts were made, click on the buttons on the left-hand side of this page. The website contains two main resources: - An introduction to UTI, MRI vocal tract imaging techniques and information about the production of the articulatory animations. - Clickable International Phonetic Association charts links to UTI, MRI and animated speech articulator video. You can find UTI films with lip video for the production of single words and connected speech for a range of world-wide English accents, on our sister website, Dynamic Dialects.
