Illustrations of the International Phonetic Association map

The International Phonetic Association publishes illustrations of the sounds of languages throughout the world. A map has been created documenting the breadth of analysis across the world: https://richardbeare.github.io/marijatabain/ipa_illustrations_all.html. The map enables people to find the IPA illustration journal article (green markers) as well as download the sound files for each language. It is a useful resource.
