Kirshenbaum, sometimes ASCII-IPA is a system used to represent the International Phonetic Alphabet in ASCII. It was developed for Usenet, notable the newsgroups sci.lang and alt.usage.english. It is named after its creator, Evan Kirshenbaum.
Like the more common SAMPA, the system uses lower case letters to represent the directly correspending IPA character. However, the mapping used to represent other characters often differs. For example -
|turned open o||O||O|
|turned script a||Q||A.|
|turned open e||3||V"|
