PLN: Antimoon IPA Although the site advertises itself as an english-learning site, the tool I found is much more specific, applying directly to English Diction and IPA. For anyone struggling with diction class, or who wants to learn their American IPA, this is an excellent tool. Especially for future choral conductors or vocal coaches. IPA symbols are the symbols we use to convey exact pronunciation, especially exact vowel sound. On the page, you will find every american IPA symbol, along with a few examples of words containing them, and the option to listen to the proper american pronunciation.
